The Effect of Heavy-Duty Pavement Concrete Mix Composition on its Physico-Mechanical Properties

Abstract

This article examines the differences in strength and porosity throughout the entire thickness of the upper and lower layers formed by the vibratory compaction of a cement-concrete pavement mixture with a non-optimal composition. Research has also been conducted to determine the effect of the sand content in the aggregate on the physical and mechanical properties of concrete mixtures for roads designed for heavy loads. Based on these studies, recommendations have been developed for optimizing the composition of road concrete and determining the integral service life of cement-concrete road pavements.
