LATU again in the more than 350 players in the Uruguayan roads were present to exchange and learn about the latest developments in local infrastructure, maintenance, mobility, road safety and artwork, among other topics.

The same Bitafal Group participated in the exhibition presenting the new rheometer (DSR) of CITEVI well as new products supported by this equipment as are the HIMA, the PG 70-28 and new level of performance emulsions (EPG) . Technical presentations were linked to the performance of the above products and the recently published book "High Performance Surface Treatments".

The opening of the Congress was delivered by President of the AUC, Ing. Gerardo Fernandez, Minister of Transport, Víctor Rossi, Director of Mobility of the IMM, Pablo Inthamoussú, the Director of LATU and IDB representative for Uruguay.

Special conferences were given by Ing. Maria Mar Colas, from CEPSA and ATEB(Spain) “Surface treatments with asphalt emulsions for low-traffic highways”, by Mr. Jorge Setelich (Undersecretary of Transport and Public Works, Uruguay) “Central Railway Project – Uruguay in progress”, from Ec. Gonzalo Márquez (Municipal Government of Montevideo, Uruguay) “Electric Mobility in Montevideo: Where are we and where are we going?”, by Ing. Fabián Schvartzer (Independent Consultant, Argentina) with “Contribution of high-performance geocells in the calculation of pavement structures” and Dr. Ing. José Ramón Marcobal (SACYR, Spain) “Contributions to pavement engineering in Uruguay: a look towards the future”

In addition a thematic table "Proposals of Political Parties for the sector" where representatives gave their vision of how we are and proposals for the next period of government was conducted.

Within the thematic blocks, more than 30 technical papers on Transport, Road Safety, Structures, management and maintenance as well as pavements are presented.

The BITAFAL Group participated with four technical papers on "Surface treatments High Performance", "Advanced study of mixtures using different asphalts", "New asphalt emulsions level of performance" and "Recycling with cement and multiple treatments locked" together with the DNV.
At the close of the Congress there was a distinction as the best work of the Congress "Implementation of a mechanistic-empirical method for pavement design in Uruguay" of Ing. Martin Scavone and Gerardo Flintsch.

The novelty of the exhibition was that the outdoor showed new Wirtgen KMA 220 recent acquisition of CVC for recycling mixtures using foamed bitumen.
We look forward to the next Congress of Roads Uruguaya that possibly be done with the IBWC XXI.

NEW INDUSTRIAL PLANT

Bitafal group expands its installed capacity by acquiring the plant Urupema

The new plant, located in Barros Blancos at km 27 of Route 8, is the new commitment to develop the local market with new products and reach the regional market with high quality products and technical level.

They are more than 5 ha in area with 2000 m2 of roofed warehouses, plant chemicals advanced and more than 1000 m3 tank where we will develop a new generation of modified asphalts and other products for road maintenance.

He is currently performing a set point and the installation of equipment, an integral vehicle scale and adapted for handling asphalts waiting to be conducting the first tests in tanks next July.

Urupema was a processing plant plasticizers for PVC industry and other chemicals, being a plant that elaborated products both domestically and regionally. The whole plant is functional and adaptable to the preparation of other types of chemical compounds advanced for road maintenance.

CITEVI is working intensively on the development of a new range of innovative products that will be available commercially in the coming months and correspondingly present at events and fairs to participate.

We will keep you informed of developments in the next editions of "Making Roads".

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.

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.

The next edition will be held from 4 to 10 April 2022 at Messe München also in the beautiful city of Munich.

En el mismo, 6 diferentes productos estabilizantes de suelos van a ser evaluados en su desempeño en el tiempo respecto a un par de tramos testigo sin aplicación de ningún producto. La Facultad de Ingeniería está haciendo una evaluación mensual del tramo para ver su evolución.

The inauguration was attended by representatives of OPP, the Mayor of Paysandu, the Director of Works of the Government of Paysandu (IDP), representatives of the Faculty of Engineering and applied products. The Telégrafo_28 / 09 / 2017_VER - for the same conditions of application of the products with the IDP, the commitment of all suppliers and adverse weather conditions that have plagued the section (over 650 mm of rain) highlighted LINK –

Assessment being conducted by the Faculty consists of a measurement by laser Profilograph IRI, counting potholes and regularity of the transverse profile.

The IDP will intervene only in sections witnesses until one of the applied products fail more than acceptable, at what will be the end of their useful life. At the end of this experiment you will have a comparison between durability of each type of stabilizer along with its estimated cost and about not implement anything.

Hopefully excellent performance of cement stabilized as road engineering has proven worldwide for decades and thankfully is being applied in our country regularly.

We will keep you informed of developments thereof.

VISIT TO THE UNIVERSITY OF MONTEVIDEO CITEVI

For the third consecutive year we visit students of Civil Engineering at the University of Montevideo in our facilities. The activity is part of the course of Civil Laboratory III specifically on aggregates, binders and asphalt mixtures.

In the same an approach is given to building materials pavement comprising an asphalt mixture, testing quality control thereof, the design criteria of the mix, an evaluation of its mechanical properties and details of the activity laboratory practice compared to those who represent its future activity, such as road builders.

The activity is focused on the design of an asphalt mixture according to the Marshall method. In principle, a theoretical review of the method and national regulations was carried out. Subsequently, asphalt mixtures with different asphalt contents were made in the laboratory and test methods were evaluated to determine the characteristics of the mixture and of the aggregates that were being used. Once the capabilities of each of the systems were determined, the students processed the information and interpreted the results.

In addition to performing conventional tests, as wear LA or mixtures dosing by the Marshall method, seek to bring students to new technologies and assays as Microdeval comment on other methodologies existing dosage.

During the day also made visits to industrial plant Bitafal Special Asfaltos and other technologies are discussed road maintenance to complement seen in the laboratory.
