ROUTE OPENING 18

Last October 10th Serviam inaugurated the work carried out on Route 18.

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.

OPENING OF ROUTE 7

They rehabilitated three sections to complete more than 82 km of Route 7 between Reboledo and Jose Batlle y Ordonez.

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.

NEW STRETCH WITH ASPHALT HiMA

Different experimental sections were carried out on Route 101 to evaluate the long-term performance of this new asphalt.

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.

12th CONGRESS OF ROADS URUGUAYA

On 25, 26 and 27 September, the biannual conference of the Uruguayan Association of Roads was performed.

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.
