INAUGURATION recoating EN ROUTE 1

novel recoating It opened to prevent reflection of concrete joints Route 1 and the new roundabout Playa Pascual.

On June 3 took place in the vicinity of the Playa Pascual new roundabout Route 1 in the opening of the section by Tracoviax between the km 67. Access and attended the same Minister Victor Rossi, the Director of Highways, Leonardo Cola, senior officials of the Municipality of San José, the staff involved in the project and as friends and colleagues at DNV and other construction companies.

The new roundabout built is the largest in the country, with circulation dual carriageway and various security features. In addition to both sides of the road sidewalks for pedestrians, accessibility ramps and bus stops were built. Furthermore, both vertical and horizontal signaling, being provided in the near future replacement of existing lighting redesigned.

As for the retreading of concrete pavement it stands IRI achieved which is below 1.2 m / km. This was achieved by a skate composed of a 6 m long and 3 sonic sensors leveling sensor (BIG-MULTIPLEX-SKY), coupled to the paver and a multilayer system, at various stages retreading as reported in the Bulletin # 94 June 2018. First a sand asphalt SAMI 2, 5 cm, then a leveling layer CAD-12 4 cm type, and finally the surface layer with an open mixture F-10 3cm. modified asphalt was used in all these layers BITAFLEX AM3. We thank the company provided confidence in providing it.

As for the retreading, to improve the IRI on the stretch of Route intervened and asphalt layer to achieve high durability, safety and user comfort slab repair work and potholes then apply three asphalt layers were made:

1) A layer of sand asphalt as stress relieving membrane (SAMI) modified asphalt made with BITAFLEX AM3.

2) A regularization layer on the gauge with a CAD-12 type modified asphalt mixture made with BITAFLEX AM3.

3) A surface layer with an open mixture F-10.

Among other topics discussed at the meeting they had presentations as "Current Status of Structural Policy", "Bolivian Seismic Design Guide", "Structural Concrete for Large Works" or "Sustainable Urban Mobility".

There was a significant presence of students in the last semesters of Civil Engineering which showed a very good technical level and interest in the issues.

INAUGURATION OF LOW RIDE IN BUENOS AIRES

Under the Walk is a 7.1 kilometer road corridor connecting the Illia and Buenos Aires-La Plata highway.

We had the opportunity to tour the recently opened Paseo del Bajo works, construction facilitating cross the city of Buenos Aires in just ten minutes already benefit some 12 thousand vehicles per day, between heavy and light. We invite you to read the note to know the details of the various stages where we were present and see pictures of such a work of engineering.

At the junction of the 25 de Mayo and Ricardo Balbín highways (Buenos Aires-La Plata), this work begins, which, although it had been planned since the 1980s, had never been carried out. The project consisted of about 7,300 meters in total length, in viaduct typologies, level sections, semi-covered trenches and open pit. The work was built in three sections (A, B and C) by 4 construction companies, IECSA, COARCO, GREEN and CEOSA. Section A consists of a viaduct and in particular was divided into two sections: A-South, which connects with the Buenos Aires-La Plata and 25 de Mayo highways, and A-Norte with the Illia highway. Sections B and C are mostly low level. Transversal crossings between Microcentro and Puerto Madero were also installed through several streets, and together with the 60,000 m² of new green spaces of squares and parks, the historical barriers that separated Buenos Aires from the Río de la Plata were eliminated. The terms of the work were 17 months for section A and 28 months for sections B and C, at an approximate cost of US$650 million.

The configuration of the highway is two lanes in each direction of traffic, each lane approximately 11 meters wide, with New Jersey TL5 concrete guardrails. The rolling course in the viaduct sections consisted of a fine leveling layer of asphalt sand with modified asphalt type AM3, about 3 cm, followed by a 7 cm layer of SMA 19. In the low-level sections, a 7 cm layer of conventional asphalt added to another 7 cm of SMA 19. Some 832 beams were placed in the viaduct sections, of which 796 were manufactured in the plant, with a double T section and lengths between 21 and 26 meters, in all alleged cases. Then there were 36 special beams which break down as follows:

- nine beams 36 meters long, 1.90 high and 120 tons, manufactured in situ, post-tensioned and mounted on spans of 36 meters above the Illia highway.

- two beams 42 meters, 1.90 tall, made in situ post-tensioned and mounted on a branch access.

- 25 beams 42 meters, height 2.5, 180 tons of which 6 were manufactured in situ, post-tensioned, and 19 which were prefabricated segments (7 segments per beam) to be assembled and tesaron in the trace. These beams were mounted on the main boards where will the lower rail level.

All the special beams were assembled by means of two frames that ran along tracks perpendicular to the layout. The beams were moved to the assembly site with an innovative traction buggy system, where they were raised and mounted above the spans. Placing the beams for the viaduct presented great challenges. We had the immense pleasure of witnessing the placement of the monumental piece of 42 meters and 180 tons, as can be seen in the photos.

Like any project of this magnitude, the work on Paseo del Bajo had other challenges, which had to be resolved with fair schedules. Among other factors, they had to work in very confined spaces, always allowing (although with difficulties) traffic at all times. In addition, when working in the vicinity of the Río de la Plata, it was also important to take into account the water table when excavating for the trenches, and also to consider sanitation services with large pipes that had to be avoided. Despite these complications, the work was completed in a timely manner, being inaugurated on the 27th of last month.

We congratulate all the professionals responsible for carrying out this magnificent work of engineering and we appreciate the kind invitation to witness a project of this nature.

in: News,Pro Bitum 2019,Travels,roads

The most important conference on asphalts Russia is held annually in St. Petersburg.

We had the pleasure of participating in the 8 Conference "for BITUM" which was performed on 4 and 5 April in St. Petersburg. More than 600 specialists from the sectors of oil refining and road from different countries gathered at the Hotel Corinthia St. Petersburg to discuss industry trends, introduce modern technologies in production and establish new contacts.

The conference was organized by Gazprom, Rosneft y SIBUR with the support of the Federal Highway Agency and the State Company Avtodor.

On the first day of the conference, an intersectoral event was held with the signing of trilateral cooperation agreements between the Federal Highway Agency, the Russian State Highway Company and the companies organizing the Conference for the application of innovative and high-quality technologies and materials. quality by increasing the durability of roads and improving the regulatory framework. The conference then became a platform for the exchange of international experiences where experts from Sweden, Germany, Colombia and the US spoke about the latest technologies and trends in the industry.

The proposed interest of Russians to sign cooperation agreements between all players in the industry of road construction is important because not only manufacturers of asphalt, designers, contractors, customers, but also the representatives of the constituent entities of the Russian Federation and municipalities are present in a dialogue platform.

According to the chairman of the board of Group of Companies AvtodorVyacheslav Petushenko, it is important to cooperate both road builders at different levels as all manufacturers of bitumen. "Road users are already seeing the results of their joint activities", Señaló Vyacheslav Petushenko.

The Director General of Gazpromneft, Dmitry Orlov indicated that "Only in unity can we solve all the problems and meet the challenges that currently exist in the development of national industry“.

“Through communication and exchange of experiences in the industry, effective management system that is not imposed from above, but is produced by industry professionals created. Without the active participation of the expert community, which has colossal intellectual resources, it is impossible to expect a successful solution of the tasks facing the industry "Said Nikolai Bystrov, permanent moderator of the conference.

According to conference participants, project implementation "safe and high-quality roads"It has a significant impact on the domestic market for road construction. Experts say the continued growth of the industry. In 2018, asphalt production totaled 6.5 million tons, the weighted average capacity utilization of industry enterprises exceeded 63%. At the same time, events like the FIFA World Cup 2018 clearly they demonstrated an improvement in the quality of roads and road infrastructure in Russia.

The use of modified asphalts with SBS Russia It has more than doubled in recent years. In 2018, the production of modified exceeded 400 thousand tons. According to experts, the growth in consumption of modified bitumen in the Russian market was 18%. In 2018, the proportion of use of modified / conventional in road construction exceeded 6%, while four years this figure did not exceed 4%.

During the two-day conference they showed that participants in the event discussed problems responsibly industry, which depends not only on the morning of bituminous binders, but also for road industry.

The Interindustrial 9th Conference "PRO BITUM“ It will be held in St. Petersburg 2 to 3 April 2020.

BAUMA 2019

The biggest event of the construction broke records of participation and exhibitors.

For the third consecutive year BITAFAL group traveled to the city of Munich to participate BAUMA. This event, held every three years, was the biggest in its history and where more than 3700 companies presented their products and services. During the 7 days of the fair, from 8 to 14 April, 620,000 visitors came from 200 countries to learn about the latest advances in technology in both civil construction and road.

This time, the fairgrounds, opened new areas reaching 614,000 m2 of exhibition, fair really an eyesore.

From Uruguay several technicians and businessmen were present to meet new products and to incorporate these technologies in our country. We can proudly assure how many construction equipment companies mention Uruguay as a benchmark in innovation and incorporation of the latest trends in equipment and techniques. This is thanks to the joint work that many of the actors in the road family have been doing in recent years.

The world's leading trade fair for construction machinery, building materials machinery, mining machines, construction vehicles and construction equipment, generated the best results in the exhibition's 65-year history. The number of visitors increased by around 40,000 over the total for the previous event in 2016. More than 250,000 visitors came from countries outside of Germany. The top 10 visiting countries after Germany were: Austria, Italy, Switzerland, France, the Netherlands, Russia, Sweden, the Czech Republic, Poland and Great Britain. The fair also saw a strong increase in the attendance of foreign visitors. China, Australia and Japan made significant gains in this group.

The most impressive stands were again the Liebherr, Caterpillar and Wirtgen. These exhibitors have whole sheds or buildings built exclusively for the fair, with exhibition equipment, meeting rooms, restaurants and shows to showcase the latest innovations.

Overall trends in this latest edition were hybrid engines for construction equipment, the 4.0 generation equipment, wireless technology for many applications and automated almost completely equipment.

Another interesting experience is the virtual reality that is being used for operator training and for different applications such as security awareness at work or even see the finished project from within.

During our visit to the city of Punta Arenas, they took us to the first and continuous kilometer zero of the southern hemisphere on the rock of Puerto Bulnes, a fortification built by the Chilean government in order to maintain the military presence in the area.

Our adventure continues and from there we pass through the Strait of Magellan until we reach the city of Ushuaia where we disembark and in a regional walk we effectively reach the first true KILOMETER ZERO in the world, with the interruption of the Beagle Channel only, but after crossing the following 17,500 kilometers we can say that the longest road in the world was traveled.

Our adventure continues and from there we pass through the Strait of Magellan until we reach the city of Ushuaia where we disembark and in a regional walk we effectively reach the first true KILOMETER ZERO in the world, with the interruption of the Beagle Channel only, but after crossing the following 17,500 kilometers we can say that the longest road in the world was traveled. Complete mistake, the roads were made by men and only in less than 100 years we managed to have that impressive network of communication and development that we need to live better every day, that is why when we arrived at KILOMETRO CERO we certified that a road was already working on Ushuaia, another in the Andes and another in Alaska at the same moment to unite like a great umbilical cord and thus be all users of that wonder.

RECYCLED CEMENT AND TMT ROUTE 15

Molinsur trust GROUP BITAFAL for the implementation of technical TMT on recycled with cement made in Route 15.

Adjusted dosing and construction conditions, has been developed excellently recycled TMD on cement. The combination of these two techniques provide a unique opportunity to build synergy routes in our country.

Recycling Portland cement is carried out very rapidly on which an emulsion is applied IRRIGATION BITAFLEX 65 P25 with sand as curing irrigation. TMD is then applied with 14 to 19 mm and gravillín stone 2-6 mm with posterior irrigation fog, all run on the same day and with the same emulsion BITAFLEX IRRIGATION 65 P25.

The surface quality of TMT shows great cohesion of the whole package, without loss of aggregates and large voids content serve several functions. For one drain water towards the shoulders reducing the "Spray" effect and leaving a proportion of feasible to be filled by binder and thus prevent any errors dose or overlap that can result in air exudates.

The results are already more than validated on Route 15 in other sections own previously executed. It is expected durability of these jobs that we hope will be adopted by more manufacturers in the short term.

NEW TECHNIQUE FOR CEMENT CRACKING CONTROL

Serviam has developed an interesting team to prefisurado recycled with cement.

Drawbacks consabidos generating shrinkage cracks of cemented materials are subject to attack because they can reduce the life of the pavement by water ingress. Usually in our country it has incorporated the technique with a heavy microcracking to mitigate these effects but there are other alternatives globally with specific equipment Compactor.

Serviam company developed a computer adapted to perform a Bobcat injecting the emulsion prefisurado IRRIGATION BITAFAL 65 at a depth of 20 cm each 4 m crosswise.

After initial compaction of the recycled material prefisurado this is done then continue working, leveling and final compaction. Of note is the use of technology to achieve grade project controlled by RF motoniveladora.

Subsequently curing the same emulsion BITAFAL IRRIGATION 65 is performed with quarry dust is released and traffic. By far the results are very good and it shows on the go using technology to control IRI. In the next few weeks they will be starting tasks paving asphalt hot mix in 5 cm surface layer.

We will see the behavior of this technique prefisurado in the future. For now, in every induced cracking and the asphalt it is necessary to prevent water ingress so hopefully a lifetime of work done.

The equipment developed by Serviam has a storage tank emulsion, a positive displacement pump, a wedge (shark fin type) of 25 cm which leaves a pipe 20 cm and a solenoid valve for controlling the dosage from Bobcat.

The fin makes a wedge about 2 cm wide in advancing the equipment is filled with emulsion BITAFAL IRRIGATION 65. Then the material of the side itself closes the wedge and leveling and compaction are performed normally. It can be seen watering cured, made with 1L / m2 of IRRIGATION 65 and 6 L / m2 of dust, marks prefisurado every 4 m in the photos below.

RECYCLING AND CAPESEAL ROUTE 60

The works mentioned in previous bulletins (Bulletin # 98 NOTE: Capeseal on Route 60) Have come to an end and the result is really very good.

The recycling works Portland cement and the Capeseal provided as wearing course have culminated in this work quality that carried out Serviam. Aesthetic and functional completion of the section is excellent and we recommend those not familiar with the technique of Capeseal visit the section from Sugarloaf to the city of Minas.

It is for the group BITAFAL proud to have been involved in the whole process, from the dissemination of the aforementioned techniques in lectures, conferences and in our book "High Performance Surface treatments"To see it come true with the quality achieved. Thank provided Serviam confidence in our products and services in each of the construction phases of the stretch.

UNIFORMITY AND QUALITY

Asphalts new terminal opened last October (Bulletin # 98) It allows great homogeneity of asphalts basis for the manufacture of emulsions and modified asphalts.

With these investments and operational changes in plant we are achieving consistent quality of our products. The new terminal allows we to emulsify asphalt batch of some 320 tons each that are constants in quality and consistency batch after batch of emulsion.

With asphalts available in Uruguay (AC30 and 150/200) we achieved a "Blend" that meets the requirements for emulsions classified by performance for our country exceeding 61 ° C in Grade Performance testing AASHTO M320 to prevent exudates in time summer.

Since November 2018 penetrations waste our emulsions for surface treatments are between 60 and 70 dmm and softening points above 50 ° C constant and predictable. We have also improved the quality of viscosities and emulsion to standardize the process of emulsification and the size of the stocks of finished product.

Today as never before BITAFAL has full confidence in the superior quality of its emulsions over other emulsions present in the local and regional market.

After liberation of the base to emulsify BLEND, ensuring PG having a suitable batch emulsion between 30 and 90 tons are performed according to the type of emulsion. We have duplicates for each type of emulsion allowing us to quietly release the batch laboratory prior to loading tanks.

The new tanks have agitators and load filters to remove any impurity or cream that may arise.

We have also implemented a system control content and temperature of all tanks of the plant that allows us to accurately adjust stocks and forecast production and delivery.

Laboratory incorporated a dynamic shear rheometer (DSR) and a large battery of additional tests to determine the quality of emulsions, not only as specified in the tender documents and the IRAM 6698 but for new global trends.

We have a stereo microscope to see the quality of emulsification and micelle performance level.

We are moving the way for emulsions level of performance (EPG) which will be the specifications of the future.

These great efforts are BITAFAL we have a commitment to national roads and we want things done right because that is our responsibility.
