Cement Grouted Macadam : A Review

Abstract

The new pavement construction is the need of an hour in all over the world and it can be seen through various researches which is being carried out. The present work consists of a surface course which consists of semi-flexible material. This provides advantages to other pavement like concrete pavement and conventional bituminous or asphalt pavement. Such type of pavement is good resistant to percolation of water to the foundation as the surface layer becomes impermeable. Such type of pavement is called as grouted macadam. This macadam should be properly studied in order to use it for economical pavement construction. It was observed by the researcher that Stiffness is mostly related to the volume of bitumen used in grouted macadams, increasing with a reduction of the bitumen volume. Fatigue performance of grouted macadams is not affected by small variations in the binder content.
