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.

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.

It IS NOT WHAT THEY SAY ...

During February we conducted two tours of much of the country to see how surface treatments behaved during the summer.

After having traveled more than 2800 km were able to verify that the problems of exudation that both resonated in the press and in the environment, are actually a small part of what has been done in recent months across the country.

We could risk to quantify the problem areas and we do not exceed 2 or 3% of total executed.

Exudation is fully controlled and are the result of a sum of different errors, based not only attributable to asphalt emulsions. We have traveled sections executed with national emulsions, RC2 or imported emulsions, and in all cases there exudates sections. A common denominator of most of them is running during the winter without the necessary precautions.

The emulsions BITAFAL ALWAYS comply with the current specification DNV which includes a penetration range of 50 to 200 dmm and we subdivide into soft, medium and hard to adjust to the realities of each work.

Every summer we adjusted basis or hard asphalts media but from now on is the quality of asphalt base will maintain throughout the year. Only order will manufacture soft asphalt emulsions that way unless there is a variable in the appearance of exudates.

You can read some recommendations to reduce the appearance of exudates below:

To prevent exudates is essential to work in good weather conditions to ensure proper curing of the emulsion without risk of premature detachment and redo work force overdosing asphalt.

If you have to work during the closure take the precautions mentioned in note below.

Other factors are very soft exudation base surface allowing penetration of the aggregate A treatment and reducing the proportion of several necessary. The same applies to well-graded aggregates that fill the gaps for the asphalt emulsion.

The lack of a suitable dosage criteria, use the same "recipes" for all treatments running and lack of calibration of equipment are key components for the job fails.

Aggregates with high dust content are also a problem because the reduced active adhesion usually increase the dosage asphalt irrespective of subsequent consequences.

Must professionalize dosage calibration, the release of the basis for treatments and especially the aggregates used.

Treatment well executed, even with soft emulsions, may not have bleeding problems ... and many kilometers executed last winter with soft emulsions which did not have problems when they reached the heats.

DOUBLE OPENING VIA ROUTE 8

Last December 12 took place in the vicinity of Route 8 to Route 82 the opening of the recent doubling of Route 8 and Route 11 between Pando by COLIER S.A.

They were 30 months of effort by the company to achieve the stated objective of doubling the route, make a new bridge and an upper passage and meet the highest standards of road safety.

14 km were retreads with modified asphalt BITAFLEX AM3, que le brindarán al tramo construido una gran durabilidad frente a las cargas que por allí circulan. Agradecemos a la empresa por confiar en Grupo BITAFAL el suministro del asfalto modificado para tan importante obra.

The inauguration was attended by the Minister of Transportation, Victor Rossi, the Minister of Labor, Ernesto Murro, the Mayor of Canelones, Yamandú Orsi, high-ranking national and departmental authorities, members of colleague companies, the MTOP, suppliers and residents of the area. During it, Hebert González was honored and remembered with anecdotes, phrases and emphasizing the capacity for work and love for what is done, which were the identity of the recently deceased director of the company. Later, Colier's direction through Eng. Juan Echeverz paid tribute to the "patron" and friend that filled all those present who were lucky enough to meet him with emotion.

Work on Route 8, Juan Antonio Lavalleja, consist of: the construction of two new traffic lanes 3.6 meters wide each, with an inner shoulder of one meter and two meters outside. Also, a bridge over the Pando stream, with a length of 166 meters, with 9.2 of road width plus a cycle track, and a railway underpass in Splice Olmos 22 meters long was constructed. The tasks required an investment of 52 million dollars.
