Design Construction and Performance of Porous and Rubbrised Asphalt Pavement

Abstract

Moreover, porous asphalts have volumetric and surface characteristics (e.g., acoustic absorption, drain ability, texture, and friction). These characteristics are influenced by both intrinsic (such as gradation and bitumen content) and extrinsic (such as traffic load) variables, and the complex phenomena and processes that give rise to them determine how they change over time. Deterioration, which consequently impacts budget, noise, and safety. Despite the deterioration of so many different and intricate qualities over time, there aren’t any standards for synergistically improving the pavement system. So, the goal of this study is to establish and validate a design methodology that, when applied to the most important characteristics of friction courses as a component of a pavement structure, works in concert. The aforementioned method is based on extensive literature analyses as well as experiment conducted in a lab and on-site over a period of time to assess how the major surface and volumetric qualities degrade over time.
