Contribution to the non-destructive evaluation of bituminous mixes by electrical measurements

The incorporation of additives into bituminous mixes is a very important technique for improving the mechanical and electrical properties of the pavement body. The purpose of this work is to present and interpret the different results of the tests carried out in the laboratory; such as FENIX direct tensile test and electrical resistivity test. In this work, we will present comparative studies between the mechanical and electrical characteristics of bituminous mixes based on conductive additives (steel fibers and graphite powder). This comparison makes it possible to classify these resulting materials as materials that have the ability to respond to different multifunctional applications.
