UPDATE SEMINAR FOR ABC (BOLIVIA)

GRUPO BITAFAL present at the Seminar organized by the Franz Tamayo University of Bolivia

The seminar organized by the Franz Tamayo University and the Bolivian Highway Administration (ABC) was held in 4 days from 14 to July 27th Through the Zoom platform where more than 100 ABC engineers were able to learn first-hand about the latest technologies related to modified asphalt and emulsions.

Speakers from various universities in Argentina, Brazil, Bolivia and Peru as well as CAF, Instituto Panameño del Asfalto y Vialidad Argentina presented on various topics related to the use of modified asphalt as well as primer emulsions and modified emulsions for treatments. Grupo Bitafal presented on "High performance asphalt emulsions" commenting on the latest trends in specifications by degree of performance and other recent developments.

STEEL SLAG AS AGGREGATE

We continue to bet on the circular economy using waste from other industries in paving

After several months of tests and adjustments in the way of classification, we were able to carry out the first section using steel slag as aggregate for surface treatment.

The most important steel mill in Uruguay, Gerdau-Laisa, generates around 10,000 tons of slag per year that ended up being buried in a landfill. With the approval of Dinama for use in road construction, it is possible to use a very valuable residue with good properties for surface treatments.

The material has excellent shape and high wear resistance in both the Los Angeles and Microdeval tests. The granulometries achieved fit very well with those we propose in the Book "High Performance Surface Treatments" achieving ranges of 2-6mm, 6-10mm, 10-14mm and 14-20mm. In terms of adhesion by Vialit plate, it exceeds 90%, complying with what is required.

The quality of the treatments carried out depends largely on the possibility of having resistant, cubic and well classified aggregates as is the case with this material. We leave you some photographs of the section made where you can see the quality of the aggregate used. We continue to take steps on the circular economy and caring for the environment in all our products and related techniques.
