Bitafal was a keynote speaker in the virtual course of the Ministry of Communications and Transportation (SCT) of Mexico and the Mexican Asphalt Association (AMAAC).

Grupo Bitafal held the inaugural conference of the "Refresher Course in Periodic Road Maintenance Techniques", a Mexican event with more than 500 participants. Below we delve into the content of the course and a free tool for the selection of surface treatments.

Organized by the SCT of Mexico and AMAAC, the course on conservation techniques aimed to update the knowledge of Mexican administration professionals. The event took place over three days, each covering a particular theme. The first day the theme was "Periodic Conservation Techniques" and Bitafal gave the first lecture by Ing. Ignacio Kröger, who dealt with the detection of opportunities and limitations in the evaluation of pavements as well as the correct selection of surface treatments. The first day was completed by important exhibitors, such as Eng. Salvador Fernández Ayala, General Director of Highway Conservation of the SCT and Dr. Adriana Vargas, researcher of the North American National Center for Asphalt Technology (NCAT).

The session on the second day dealt with the theme of "Good practices in conservation treatments" with presentations on gravel, microagglomerates, sealing and caulking of cracks. The presentation by Ing. Jorge Alarcón on his experience in the reuse of milled material (RAP), the different recovery techniques and the configurations of asphalt plants for a greater incorporation of RAP was highlighted on that day.

On the third day, “Asphalt mixes as conservation techniques” were studied in depth, commenting on the good practices of milling, patching and discontinuous mixes. Eng. Francisco Ramos commented on the guide on "Road Conservation Procedures and Techniques" developed by the SCT and detailed the highly recommended "Conservation Treatment Selection Tool" available for free at .

We thank the SCT and AMAAC for the invitation and for having the initiative to share crucial issues for the sustainable development of Latin American roads. Follow us on social networks to find out when the videos of the course are published.
