Effect of Aggregate Proportion and Skeleton on the Strength of Porous Asphalt Mix

Abstract

Investigating the skeleton behaviour of dry aggregates and the characteristics Of Indirect Tensile Strength (ITS) of various open-graded bands is the prime focus of this study. The skeleton band has an impact on mechanical characteristics. To make porous asphalt mixes’ skeletal strength greater, aggregate proportion studies are necessary before evaluating its performance. So, the current research on how the gradation band behaves concerning aggregate proportions is studied in this paper. The coarse and fine aggregate percentages on the gradation that affect tensile strength values vary in this paper. The coarse content effect on the ITS value lower side and fine proportion on the gradation significantly affect and indicates the compacted sample’s binding property. In this paper, different couple conditions also effect the ITS values. The porous asphalt mixture’s main mote is to improve air void content and drainage facility while improving durability and strength parameters.
