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.
