The present models for the calculation of the adhesive coefficient of friction between tire and rubber in wet conditions only consider the direct contact between the rubber and the basalt surface . To concretely analyse the adhesion phenomena occurring it is necessary to incorporate the contribution of the adhesive forces arising from the

2018-4-18The extent to which a given aggregate is considered suitable is determined largely by its petrological examina-tion. In this analysis rock type geological and chemical properties texture and mineralogy of ballast particles are examined. After suitable rock types have been determined durability testing is conducted. Individual particles are

High friction surfacing HFS bonded to a road surface at high risk locations has been shown to significantly reduce road fatalities and serious injuries i.e. HFS saves lives. Calcined bauxite is the preferred aggregate for use in HFS systems due to its unique ability to resist polishing and abrasion by vehicle tires. Calcined bauxite is expensive negatively impacts the environment due to
