TRASUTRA (Surface treatments for quick open to traffic) are an excellent solution to renew the surface properties of pavements. The European regulation UNE-EN 13108-9 allows combining different requirements and select categories for different properties. In this article you will find out more about the used criteria to formulate ultra-thin mix technology as well as the lab test results.
This work is presented as sample of the collaborative work between two companies and a university, within a cluster formed by the PADECASA-UAX cathedra and the Kao company, being in the first stage of this research for the development of Asphalt Ultra-Thin Layer (AUTL) mixtures for its manufacture with conventional binders with additives allowing to reduce temperatures.
In addition, numerous tests are currently being carried out on these mixtures in the ROADLAB SACYR-UAX laboratory, with the purpose to verify and validate performance and environmental impact of TRASUTRA compared to current AUTL techniques
