PROPERTIES OF ASHPHALTIC CONCRETE COMPOSITION FOR DYNAMIC TRAFFIC LOAD APPLICATION

Abstract

The performance and service life of asphalt pavements are significantly influenced by the dynamic loading imposed by traffic. Understanding the response of hot mixed asphalt to dynamic loading is significant for designing resilient and long-lasting road networks. To design a lasting asphaltic pavement, the properties of the constituent’s elements must be checked for adequacy. Hence, this paper presents the physical properties such as AIV, Bulk densities, ACV, Specific gravities and some other properties of the Bitumen. With the preliminary/physical tests conducted so far, the materials demonstrated high possibilities of usage for road pavement because of their strength observed from specific gravities values of 2.40 and 2.65 for dust and fine aggregates, bulk densities of 1.86g/cm3 for dust, 1.68g/cm3 coarse and 1.46g/cm3 sand. The aggregate impact value was found to be 8.78% and crushing value of 20.06%
