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.
