SURFACE TREATMENT COURSE WITH THE AUC

The Uruguayan Association of Roads conducted the course on Surface Treatments with 50 professionals from the sector in June and is preparing its repetition for the first days of July.

Last June 14th The Surface Treatments course taught by Ing. Ignacio Kröger was carried out in virtual mode, one of the courses within the Diploma program for Road Works Technician (DTOV) taught by the AUC. On this occasion, specific topics of material selection, design, construction and good practices were discussed, in front of an audience of 50 people, including engineers, assistants, foremen, laboratory workers and students.

The objective of this course, in addition to training in these specific topics, proposes to eliminate several prejudices that still exist at the national level about the efficacy of surface treatments, and to convince that instead of "cheap" and that "they require a lot of maintenance" are the options more cost efficient for road maintenance.

Due to the great interest in this subject, the AUC plans to repeat the course on the day July 5th, also in virtual mode. Registration closes this week and there are limited places. If you are interested in participating, write before Friday to Ana Damonte in secretaria@auc.com.uy

9TH TECHNICAL DAY OF ASPHALT

The biannual event of the Uruguayan Association of Roads was held in online format

The virtual activity co-organized with the Permanent Asphalt Commission (CPA) and the Argentine Highway Association (AAC) had a great attendance of almost 450 people from all over the world.

In this edition, emphasis was placed on modified asphalts for asphalt mixtures such as the new highly modified asphalt (HiMA), which we have already delved into in previous editions (Nota HiMA) and novel experiences with AM3 such as the recapping of Route 1 carried out by Tracoviax (Note route 1).

We hope to continue having such an active participation in person as well as virtually in future editions.

The conferences were held on the 22nd and June 23 through the AAC platform. They began with a conference of the Ings. Rafael Lopes Martins and Gary Fitts from the Kraton company doing an "Introduction to high performance modified asphalt (HiMA)", technology introduced in Uruguay by GRUPO BITAFAL with the support of the Kraton company in the development and Colier in the execution of the section test. This technology has been extensively studied at CITEVI and is part of the degree thesis of BITAFAL Engineers, Carlos Pfeiff and Ignacio Kröger (Thesis Note: https://bitafal.com.uy/novedades/desempeno-de-asfaltos-altamente-modificados/).

Then for the CPA, Eng. Alejandro Bisio, who until a few months ago was in charge of the Research and Development Quality Management of the National Highway in Argentina, made an excellent overview of the “Asphalt mix design methods”.

He Tuesday June 23 opened the day the Ings. Diego Larsen and Lisandro Daguerre with “Solutions for high performance pavements” where they detailed the 200 km project with HiMA asphalt carried out in Argentina on Route 9 (Rosario-Campana) and other sections with high modulus asphalt.

For the closing, Eng. Marcelo Borrelli detailed what the Tracoviax company had done in the "Rehabilitation in asphalt mixture of Route 1 double track between accesses to Montevideo and Santiago Vázquez" where modified asphalt was used BITAFLEX AM3 for the three layers of the overcoat, an asphalt sand to delay the reflection of cracks, a semi-dense one for leveling and an F10 for rolling. For more information about this work you can see in our BLOG (https://bitafal.com.uy/novedades/arena-asfalto-con-am3-en-ruta-1/) or in the presentation of the day.

The presentations are available on the AUC and AAC websites (http://www.aacarreteras.org.ar/noticia-jornada-asfalto.php).

Day VIII Asphalt

The Uruguayan Association of Roads He organized the eighth edition with a large turnout of audience.

A new edition was held at the Holiday Inn Hotel on August 13 Asphalt Technical Seminar, Event held biannually in our country.

The Permanent Commission of Asphalt (CPA) of Argentina actively participated, as usual, with three technical presentations area recognized the road as Ing. Hugo Bianchetto, Ing. Adrian Nosetti and Ing. Mario Jair. Of Uruguay they presented the Ing. Faustina Keuliyan on modified asphalts and Qco. Santiago Kröger presenting the new practical technical "Gravillados in Uruguay" manual.

En esta edición se hizo bastante hincapié sobre el control de los áridos usados en mezclas asfálticas así como otros temas de interés para el sector. La sala elegida estuvo colmada durante toda el día ya que participaron mas de 150 técnicos vinculados a la vialidad nacional y de Argentina. Esperamos seguir teniendo una participación activa en próximas ediciones y en los demás eventos que se organizan en nuestro país. Los invitamos a conocer los temas tratados en el siguiente enlace.

Course Assessment Roadways

Bitafal said this in the course of UNR graduate of Argentina organized by the AUC in Uruguay.

In the last month, from 26 to 29 June, the Evaluation Course Walkways was performed by professors Marta and Oscar Giovanon Pagola, Institute of Applied Mechanics and Structures (lower) At the University of Rosario.

The course starts demonstrates the commitment that exists in the national road on these issues and attended by representatives from Grinor, CIEMSA, Serviam, CVC and MTOP officials, OPP and IM, in days of intense participation.

Among the topics discussed it is highlighted:

The objective of auscultation of pavements.
Analysis of the different parameters of pavement evaluation: longitudinal deformation (IRI), transversal deformation (rutting, sinking), cracking, bumps and surface defects (exudation polishing aggregates).
Review of the most commonly used for evaluation of these parameters equipment. Exposure of the most modern methods.
combined deterioration indexes: Index state Serviciability Present Index (PSI), Pavement Condition Index (PCI).
Importance of tire adhesion road (Macrotexture and coefficient of friction).
structural monitoring of roads (Benkelman, Lacroix, FWD, LWD).

In conclusion, the importance of assessing roadway stands, both structurally and superficially, to determine the prioritization of improvement projects and efficient maintenance of our roads.

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.
