ASPHALT TECHNICAL WORKSHOP 7th.
Monday July 4 took place in the Crystal Tower Hotel Montevideo 7th Asphalt Technical Seminar organized by the Uruguayan Association of Roads in conjunction with the Standing Committee of Asphalt Argentina. It was attended by nearly 110 national road technicians who listened and participated in conferences exhibitors from Uruguay, Argentina and Chile.
The talks were on current issues of technology paving Uruguay from the use of Capeseal, the bitumen stabilized materials as those used in Route 3, to the performance of thin asphalt mixes F10 type, such as that in Ruta Interbalnearia recently.
Mr. Paternostro began with “Cape Seal: General concepts, national specifications and local examples” showing the results of the first sections carried out in Uruguay, both in its good macro-texture and in its impermeability, as well as the specifications currently used. Then, Dr. Ing. Fernando Martínez (Argentina) from IMAE presented "Prediction models of the rheological properties of asphalt binders", in which empirical tests such as penetration, softening point and Brookfield viscosity are used to predict rheological properties of asphalt binders. asphalts quite tightly without the need to use an expensive rheometer (DSR).
Eng. Rosana Marcozzi and Dr. Francisco Morea (Argentina) from LEMIT presented us with “Experiences in Argentina with warm asphalt mix technologies. New tests applied to the characterization of its performance ”, showing the good behavior of this type of mixture in the experiences carried out and opening the debate on its application at the regional level. In Uruguay, only one section was completed in 2012 but we are working from BITAFAL to repeat the experience and draw better conclusions.
During the afternoon Ing. Germán Bavdaz (Argentina) told us about the "evolution of physical parameters of asphalt mixtures after 14 years of service", focused on the performance of such thin mixtures F10 on the Autopista del Oeste, one of the busiest in Argentina.
For closing Eng. Joaquim Kemp (Germany) made an interesting presentation on "BSM -Materials bitumen stabilized. Current state of technology ", a technology that is already being implemented in Route 3 and has a very promising future in Uruguay.
