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.

INAUGURACION ROUTE 8 melo-Aceguá

the section built by the company CVC on Route 8 connecting Melo with the Brazilian border was opened.

On 10 September the ribbon cutting took place in the village Isidoro Noblía found in the newly renovated section. The ceremony was attended by Minister Victor Rossi, the Mayor of Cerro Largo, Pablo Duarte, representatives of the company, DNV and other national and local authorities as well as colleagues and friends.

The section was recycled in 9 m and then a road of 7.2 m was conducted in double bituminous treatment with fog. In some sites existing sewers widened and conditioned with asphalt some sections as traversing Noblía.

Recycling cement was performed in 25 cm depth giving a great bearing capacity to stretch. irrigation curing is then performed with

Recycling cement was performed in 25 cm depth giving a great bearing capacity to stretch. irrigation curing is then performed with Emulsion IRRIGATION 65 which allowed the release to traffic during last winter without problems. Bituminous simple treatment was performed on the 9 m wide while the fog twice using only road always Emulsion IRRIGATION 65 P25.

Exudation problems that appeared last year were already controlled in January and hopefully a good pavement performance this season and next summer following. The sealed surface texture was evenly across the entire width making resemblance to a asphalt.

We commend the company for having completed all the sections in very good condition and high quality. It is expected durability and enjoyment for users who can circulate in a safe and comfortable route.

FIRST TRANCHE OF ASPHALT IN URUGUAY HiMA

the first experimental section using highly modified asphalt (HiMA) was performed in Uruguay

The new highly modified asphalt (HiMA) developed by sion, He was executed by Necklace last August in the widening of Route 101. The section in question consists of 600 meters above prior to entering the roundabout junction Nicolich (direction Montevideo) outside lane. The aim of HIMA provide durability to asphalt, primarily because of its outstanding resistance to cracking and permanent deformation.

The original project consists of a black base with conventional AC-30 asphalt 12 cm on which a road surface with 5 cm AM3 is then applied. Colier was proposed, with the approval of the MTOP, 600 m replace the AC-30 HIMA of which 300 m in thickness was reduced to 10 cm (17% reduction).

Asphalt (17)

And extracted with witness samples of the asphalt plant will proceed to perform tests of dynamic modulus, and fatigue loaded in four-point beam wheel. With structural package information and research, it will proceed to use mechanistic empirical design programs, such as BackViDe (IMAE) to predict their behavior.

We appreciate the confidence Colier MTOP and apply technology to allow himâ for the first time on our roads. The research results will be presented at the XII Congress of the Road Uruguaya on 25, 26 and 27 September and the XX IBWC Mexico 25-29 November.

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.

New equipment for slip resistance CITEVI

Release Pendulum TRRL (British Pendulum Friction) to determine the coefficient of slip resistance in path 102.

Following the course Walkways assessment of the AUC, Measuring the skid resistance on asphalt Route 102 was made recently built by company C.V.C. with the British Pendulum CITEVI.

Slip resistance assesses the non-slip characteristics of a pavement surface and is directly related to the micro-texture of the aggregates used. The test consists of measuring the energy loss experienced by a pendulum fitted at its end with a rubber shoe, once it touches the surface to be tested. This loss of energy is registered by a mark on the graduated plate that contains the equipment.

Citevi Archives - Page 2 of 3 - Grupo Bitafal

With respect to the study section, said coefficient was determined in the new and in the old asphalt layer. In both cases, the test gave a value between 60-65, with a high repeatability in the measurement. Sections of the Carrasco Airport and the Interbalnearia were also tested, exhibiting similar values. Magdalena Pastorini and Nicolás Vaz from the MTOP were present to evaluate and discuss the results obtained.

Teachers consulted the University of Rosario, Marta Pagola and Oscar Giovanon, confirmed that the value found is good. They also clarified that the value tends to decrease with the level of traffic, and if it remains, it may be due to a not very good Los Angeles wear value, to the extent that the particles suffer small detachments (recovering their microtexture) when At the same time they tend to be polished. Finally, Marta comments that as an example, the Olavarría granite in the Province of Buenos Aires, has an initial value before polishing of the order of 65, and after polishing of 40. That final value of 40 is reached in 5 , 10 or 15 years depending on traffic and dirt conditions on the road.

As a final observation we conclude that the pendulum is very sensitive to the texture: if the mixture was kneaded, but still with exposed aggregates can give similar values. Therefore, to fully assess the slip resistance, it is advisable to supplement it with the patch of sand.

We must pay attention to these factors as they influence the behavior of the tire with the pavement, especially in wet conditions. Laboratory sion It has the equipment available to evaluate this parameter.

Capeseal technology tendered by MTOP on routes 12 and 108.

Capeseal technology takes hold in Uruguay with the first project awarded in this mode by the MTOP.

The company Emilio Alvarez Diaz S.A. it's found rehabbing a stretch of 32 km of Routes 108 and 12 in the Department of Canelones. The work consists of a charge in some areas and then performing a site recycling in 20 cm depth with 3% Portland cement and subsequent Capeseal treatment involving the execution of a simple treatment and bituminous cold microsurfacing above.

In this case the application of simple treatment is performed with emulsion IRRIGATION BITAFAL 65 at between 1.2 and 1.4 L / m2 and a gravel 14-20 mm applied between 13 and 15 L / m2. Once cured, the treatment is swept and the company R & K Engineers applies a cold emulsion microsurfacing BITAFLEX MICRO 62 P25 at a rate of about 14 kg / m2. The aesthetic completion of the work resembles an asphalt binder and provides an excellent Macrotexture giving greater security to the pavement.

There are several sections already implemented this technology as Route 55 or Route 69 successfully suggesting that the development of the same in the coming years will grow. So soon in the coming months the company Served S.A. You will be running a section of Route 60 Route 12 and in the Minas with Capeseal.

We believe that it is essential to make a good stable base for the Capeseal will play as a surface treatment lasting many years both in function and waterproofing in adherence with the tire without losing the aesthetic quality.

The use of modified emulsions for both simple treatment as for microsurfacing use should be binding as the adhesion achieved with much higher aggregate in respect to unmodified emusiones. In turn the selection of aggregates for both treatments should be carefully performed for an appropriate duration.

We hope to inform them about future works Capeseal in the coming months and leave you with some pictures of the work done.

Opening exchanger Route 1

04 April 2018
in: DNV,Bitafal group,Molinsur,Top,News,route 1

The company Molinsur He opened last March 22 Exchangers Route 1 Camino Camino Cibils and Tomkinson.

The inauguration was attended by the current Minister of Transportation and Public Works, Victor Rossi and his predecessor, Enrique Pintado, as well as other DNV authorities, construction companies and friends. During the ceremony, the great challenges involved in a work of this magnitude and investment, estimated at over $260 million, were highlighted. The highlights were the large volumes of natural material moved to optimize the construction of both interchanges as well as the various inconveniences encountered in the execution of a work with a traffic greater than 12,000 vehicles/day but that has solved an enormous traffic junction that had been generated in recent years due to the proliferation of industrial and logistics projects in the area.

La obra en la intersección de la Ruta nacional Nº1 con Camino Cibils consiste en una solución a desnivel donde la circulación en la ruta se realiza en forma superior, manteniendo Camino Cibils y las ramas auxiliares su nivel original. La elevación de las calzadas de Ruta 1 se realizó con un puente de hormigón armado y los terraplenes de acceso correspondientes. La rasante de la ruta se eleva unos seis metros respecto a su cota actual, dejando un “gálibo libre” bajo el puente de 5,5 metros.

El puente consiste en una estructura compuesta por muros de apoyo extremos y un apoyo intermedio de cuatro pilares y la correspondiente viga. El cruce se complementó con la construcción de dos semi rotondas que facilitan la distribución del tránsito para efectuar las diferentes maniobras posibles.
