摘要：	Both flexible and rigid pavements are linked with various advantages and disadvantages. So to overcome the disadvantages of both conventional pavements, a new type of composite pavement Cement Grouted Bituminous Mix, is being acknowledged. Cement grouted bituminous mix consist of high voids open graded bituminous mix (with suitable aggregate gradation, bitumen type, optimum bitumen content) compacted with suitable number of blows so that there are 25 to 35% air voids in them, interconnected with each other, the cementitious grout with high workability and high strength is then poured into the open graded bituminous mix so that all the voids are filled and to achieve full depth penetration. The bulk density, porosity can be determined for open graded bituminous mix. The fluidity using Marsh cone funnel method and compressive and flexural strength of cementitious grout can be determined at different water content. The cementitious grout at optimum water content with high flowability and high strength is taken to fill the voids of open graded high voids bituminous mix. The prepared samples with full depth penetration of cementitious grout for Cement Grouted Bituminous Mix can be tested for Marshall Stability, Retained Marshall Stability, Indirect Tensile Strength, Retained Indirect Tensile Strength, Resilient Modulus, Compressive Strength, Flexural Strength, Skid Resistance, Abrasion Loss Resistance, Marshall Immersion test, Freeze-thaw splitting test, Moisture Susceptibility, Hamburg wheel tracking test, Three Point Beam bending test, Four Point Beam bending test for Low temperature crack resistance, Resistance towards oil induced damages as per various research papers. CGBM shows better results than conventional BC mixes, thus can be used in the place of BC wearing course in terms of the studies done by various researchers.
