Effect of Grades of Binder on Properties of WMA Mixes

Abstract

WMA(Warm Mix Asphalt) technology is an emerging technology in today modern world which gives us better results as compared to traditional hot mix. In this an additive/chemical is added(Bitubuild WM) to the mix which gives us higher density and high strength. A total of 56 samples were made and various properties were studied such as Voids Filled With Bitumen(VFB),VMA(Voids in Mineral Aggregate), Marshall Stability Value, Flow value etc. As it requires less production temperature and lesser mixing time as compared to conventional hot mix consumption of fuel is reduced Also it produces less carbon emissions thereby making it eco friendly.
