The skid resistance of road pavements is dependent on mineralogical properties the aggregates, as well their ability to resist polishing over time. This defined aggregates wear tires. It characterized in laboratory by using a test called "PSV: polished stone value", allowing give, from coefficient, an assessment quality view friction action vehicle Our study consists analysing and modelling based SEM XRD analysis. Three analytical techniques formed basis this : nonlinear regression, principal component analysis artificial neural network. For these purposes, six quarries covering different Algerian area were chosen, 28 samples with two for each quarry used determine value results found shown that composition doesn’t play key role initial aggregate micro-texture, but very strong correlation exists between tested according calculation sum squared residual normalized error. was also be most reliable robust technique estimating resistance.
