Design and performance characteristics of cement grouted bituminous mixtures - a review

Cement grouted bituminous mix (CGBM) is a composite type of pavement surfacing prepared by injecting cementitious grouting material in porous asphalt mixtures under the effect of gravity. Over the past few decades, CGBM is gaining attention due to its numerous advantages over flexible and rigid pavement. Several researchers conducted various laboratory and field studies on CGB mixes using different grouting materials. A comprehensive review of the aggregate gradation, binder type, composition of grouting materials, their effect on the mechanical properties and performance characteristics of CGB mixes, micro-mechanical analysis of CGBM, effect of reclaimed asphalt pavement (RAP) on CGBM are summarized.
