Study on the Performance of Bituminous Mixes for Road construction using Non conventional Materials

Abstract

Pavements made with plain asphalt mixtures are subjected to premature failures due to the newlineexposure to moisture. This paper focuses on the effect of some selective non-conventional newlinematerial in bituminous mixes. In this study steel slag, fly ash, waste glass powder, CENEX newlineand Crumb rubber is utilized for preparation of bituminous mix. In this investigation the newlineeffects of these materials on the performance of asphalt mixes for road construction is newlinestudied. In this study VG30 binder is modified with CENEX and Crumb rubber polymer newlineat different percentages such as 0%, 2%, 4%, 6%, 8%, and 10% by the weight of the binder. newlineThe optimum CENEX and Crumb rubber contents are 6% and 8% respectively as er the newlinestorage stability test. Based on the Marshall Mix Design, the optimum amount of fly ash newline(FA) and glass powder (GP) is 60% and 30% respectively in lace of stone dust. newline
