Simulation of the influence of mineral materials' homogeneity on the stability of asphalt concrete mixes grading

Abstract

The article analyses the homogeneity problem of asphalt concrete mixture (ACM) used in road pavement. The average values of an ACM lot composition and physical-mechanical parameters shall comply with the requirements of the project and standards. Another important factor is that the amount of components in separate ACM batches influencing on the homogeneity of the lot's structure and characteristics would fluctuate within the minimum narrow interval. The variation interval of coarse aggregate, fine aggregate and fillers' amount in ACM and its grading in the lot is influenced by the stability of the materials' grading used when producing the mixture [...].
