In the post globalization era, India is witnessing significant growth in every sector which is evident by rapid growth in infrastructure developments. The country is building a huge network of expressways, national highways and rural roads and improvement programs involving large investments. The durability of the road surfaces depends largely on the type and quality of bitumen used and quality control exercised in the production, transportation, mixing, and compaction, to cope up with ever changing rapid growth of laden vehicles with time posing heavy stresses on roads. It is the prime responsibility of researchers, contractors to use such material which modifies the properties of Bitumen and imparts additional strength, elasticity and other beneficial properties to make it better able to withstand high traffic loads, extreme weather conditions and other forms of stresses. Previous studies on CRMB 55 for moderate climatic areas suggest that use of it leads to excellent pavement life, driving comfort and low maintenance. In this present study, initially paper deals with scientific analyses physical properties for crushed stone aggregate for Dense Bituminous Macadam (As Per MoRTH Table: 500-8). Properties are carefully accessed of CRMB 55 with and without addition in small doses of Chemical Zycosoil to fulfill the basic requirements of standard codes. Different mix design characteristics were determined out using Marshall Method for Dense Bituminous Macadam using CRMB 55 with and without addition in small doses of Chemical Zycosoil.
