Reclaimed Waste Materials in Sustainable Pavement Construction

Abstract

This chapter provides an in-depth but brief overview on the possible use of various waste materials for sustainable pavement construction. It compiles a literature review on the research done on such materials and highlights the current issues. IntroductionPavement construction involves consumption of large quantity of construction materials. Some of these construction materials are available in natural form and some are manufactured (from naturally occurring raw materials). Due to the rapid growth of infrastructure, naturally available good quality construction materials are gradually becoming scarce. Consequently, there is an increase in the transportation cost for acquiring good quality materials. Thus, there is a need to develop or search for alternative materials for road construction.On the other hand, large quantity of byproducts are generated from agricultural, construction and demolition, industrial and domestic sources (Aravind and Das

Estimation of Appropriate Filler Quantity in Asphalt Mix from Microscopic Studies

“…are being utilized as alternative to conventional fillers (Sharma et al 2010;Das and Swamy 2014;Huang et al 2009;Karasahin and Terzi 2007;Kuity et al 2014;Mills-Beale and You 2010;Sargin et al 2013;Taha et al 2002;Xue et al 2009). Given that the specific gravity values of some of these alternative fillers may significantly be different than the conventional ones, use of weight proportioning may result in application of undesirably low or high quantity of filler in the mix.…”

Effects of moisture on warm mix asphalt containing Sasobit

“…The asphalt industry has incorporated reclaimed asphalt pavement and other industrial by-products and waste materials into asphalt during the past few decades [1]. Over the last decade, Warm Mix Asphalt (WMA) tech-nology has emerged, which lowers greenhouse gas emissions, reduces exposure of workers to asphalt fumes, and minimizes the use of natural resources [2].…”
