OPENING OF ROUTE 50
Serviam inaugurated the section linking Route 1 with Tarariras
From the 25 to the November 29th He was held at the Performing Arts Center of Guadalajara a new edition of the most important congress in the world of asphalt. This time more than 800 technicians from 27 countries were present to show progress in binders and asphalt paving technology.
The strong presence of Uruguay was to ratify the realization of the XXI IBWC in the city of Punta of the East in November 2021. The launch was performed by a campaign of expectation during the Congress with a stand of Uruguay, an information campaign through leaflets and finally the announcement at the closing ceremony along with a video prepared for the occasion.
Organized by the AMAAC (Mexican Association of Asphalt), the WHAT XX It was held in conjunction with the Expo Asphalt Mexico and consisted of 5 days of intense knowledge sharing and closer ties between the different actors in the world of asphalt.
They presented more than 150 technical papers in various forms such as plenary lectures 2 auditoriums and simultaneous presentations in the same room with multiple screens and in which participants approached according to topics of interest.
There were also six lectures by prominent experts who spoke on asphalt mixes, infrastructure, design methods and auscultation of pavements.
Uruguay was present with 10 technical papers presented of which 7 were performed oral presentation format. Bitafal group He presented on emulsions degree of performance on mixtures with highly modified asphalts and on agile trials DSR (rheometer) to determine characteristics of asphalt mixtures. Serviam presented a paper on the design and implementation of a foamed bitumen recycling by Ing. Faustina Keuliyan and also on the rehabilitation of Route 60 with the Capeseal technology by Ing. Rodrigo Tejería and Pablo Carranza.
Furthermore Eng. Oscar Giovannon (Arg.) Presented the thesis of Ing. José Luis Martucci on recycled foamed performed in Route 3 and James Kröger presented thesis Ing. Gerardo Fernandez on primer emulsions.
He Tuesday in the afternoon, in a special session, Bitafal Group presented his book "High Performance Surface Treatment" of which were delivering copies of the same to all participants and which had an excellent reception.
The week was full of hard work broadcast next IBWC to be held in Punta of the East, first with the dissemination of material on Uruguay and customs, then on our natural beauty and closing Tipped East and an express invitation to participate in the XXI IBWC to be held in 2021 with a promotional video. We're on track and we will fulfill the expectations of all "cileros".
Nuevamente "one more!"
The consortium has six work fronts are doing widening platform, recycling with cement existing pavement 20 cm and placing an asphalt mixture with modified bitumen 4 cm.
Asphalt selected by the Consortium is a modified asphalt type PG70-28E supplied Bitafal. It is a AM2 according to IRAM 6596 standard but very close to a AM3. We invite you to know details of progress.
The excellent quality of the cement asphalt type PG70-28E it has been shown in a recent study of different mixtures were made in the 12th Congress of the Road Uruguaya. The same improvement was obtained 3 times in both the resistance to permanent deformation as compared to fatigue over conventional asphalt type AC-30. This classified as asphalt for heavy traffic (Extremely Heavy) AASHTO T350.
We had the opportunity to visit the front CVC work of the company, where they could see the different stages of the reconstruction of Route. A first cleaning stage and widening strip, then the recycling train with portland cement to which was followed by a curing irrigation Emulsion Bitafal Riego 65 and finally applying the front paving asphalt mixture with PG70-28E.
In the other sections we visited this time we see the company Frivial focused on clearing embankments to improve longitudinal profile of the route but turn has a front cleaning, widening and recycling and the company Emilio Diaz Alvarez preparations to start recycling and near the intersection with Route 5. the front paving of this company is doing the stretch peach-Trinidad at a good pace.
We want to highlight the incorporation of technology from different companies, 4 m rules for Pavers, automatic motor grader control systems, oscillating roller compactors, among others, as well as safety and tidiness of the works.
We thank the Consortium and contractors the confidence provided for supplying important input as is the modified asphalt and emulsions both common or modified. We are already preparing to visit the remaining work fronts from the city of Trinidad to Mercedes so keep you posted shortly.

Addition was performed on the sections still had good structural condition but any sign of surface damage, a micro cold emulsion BITAFLEX MICRO P25 62 with excellent quality implementation. We commend the company for work performed and the confidence provided.
The inauguration took place in Pueblo Rincón in the presence of the Minister of Transport, Victor Rossi, the Director of Roads Leonardo Cola and other members of the MTOP. In turn participated the mayor of Vergara, representatives of the Treinta y Tres, colleagues and friends.
A detail of execution and the new control technique mentioned cracking may be found at: https://bitafal.com.uy/nueva-tecnica-de-control-de-fisuracion-para-cementados/
Tracoviax, Meliter and Colier were in charge of the rehabilitation and widening of carriageway to reach a total width of 11 meters. where recycling was performed with cement to increase the bearing capacity. As for the surface layer double bituminous treatment was conducted with watering fog in the driveway of 7.2 meters. and then banquinas simple bituminous treatment. Contractors trusted BITAFAL supplying the modified emulsions BITAFLEX P25 and P40 IRRIGATION 65.
In addition to work on the route they were made extensions and reinforcements of bridges over streams and Mansavillagra El Potrero and a layout correction in Reboledo making a bypass to such people.
The opening last September 19 was held and attended by Transport Minister Victor Rossi, the Director of Roads Leonardo Cola, elected officials and representatives of the Municipality of Florida and Lavalleja and several colleagues from other road companies of the MTOP and suppliers.
It was carried out in 4 stages: First in Cerro Colorado (Alejandro Gallinal) the Tracoviax company made the ribbon cutting of its section, then a toast was made at the San Pedro del Timote farm, then the opening of the Meliter section was held along with the inauguration of the two bridges mentioned above. Finally, late in the afternoon, the inauguration of the Colier section was held, with the presence of the Mayor of Lavalleja, Adriana Peña.
The work done in this particular stretch, which involved an investment of 530 million pesos, in addition to the sections already opened in Fraile Muerto (along with a new bridge) and between Casupá and Reboledo few years ago. On the other hand these same companies are working in two tranches more to the north of the newly opened. It is estimated that by the end of this year Route 7 will find 80% in very good condition.
We invite you to know details of the work done on the link below: https://www.presidencia.gub.uy/sala-de-medios/videos/ruta-7-mtop-victor-rossi-rehabilitacion-530-millones-pesos-invertidos
The new generation Hima asphalts (Highly Modified Asphalt) high content of polymers in its structure, allows for a significant increase in performance of the processed mixtures, used for traffic routes highest, or thickness substantially decreasing or way for implementing urban mixtures without losing workability conditions.
In the recent sections carried out on Route 101 together with the COLIER company, we achieved different combinations of asphalt in the base layer and in the tread layer and even with reduction of thickness in the sections with HiMA. We are happy to see that the behavior in the mixing plant and during its application is carried out at temperatures similar to the mixtures with AC 30. In the laying and compaction operations a very good densification is noted with just 2 to 3 passes of a smooth roller. The drivers were satisfied with the ease of the operations, especially in compaction.
The sections executed are located on Route 101 in front of the Science Park, between the roundabout of said park and the traffic lights of Colonia Nicolich. There a base coat was made in different alternatives. With the planned solution of 12 cm with AC30, then a section with HiMA in 12 cm and to finish a section in 10 cm. Then in the tread layer it was complemented by combining the previous ones with two asphalt, the AM3 foreseen by the project and the HiMA itself. This layer in single thickness of 5 cm.
Therefore we will have a test track with AC30 in base and HiMA in rolling, HiMA in all the thickness (and a section with reduced thickness) and HiMA in base and AM3 in rolling. This experience so close to our plant will allow us to monitor their evolution over time and draw conclusions.
We can anticipate, due to the results that we obtained in the laboratory and that were presented at the last Uruguayan Highway Congress, that great durability and performance are expected from the sections that have HiMA, which are also supported by experience worldwide.
Regarding the handling of this asphalt in the plant and on site, substantial improvements are achieved due to the low mixing and compaction temperatures, similar to those of conventional asphalt. We invite you to see some photos of the experience.
