A Study On Use of Cement, Lime and Stone Dust as a Filler in Bituminous Concrete Mix

Abstract

Pavement constructed with bitumen, aggregate and filler is known as flexible pavements. Bitumen is used as a binder material; aggregates provide appropriate strength and filler is used to fill the bituminous layer void. Mainly we use cement as filler nowadays, as it is essential for better environmental conditions to utilize the waste materials as filler but it is also mandatory that material also fulfils the desired design characteristics. In this study we used of materials as filler to give better outcomes with the help of concern laboratory examination. The filler used in this study are cement, lime and stone dust. The test conducted were Ductility, Penetration test, Viscosity, Softening Point, Flash Point test and Marshall Test. From Marshall test optimum binder content (OBC) was determined. The test result obtained showed that stability value for lime and cement was maximum at 5.5% of bitumen.
