In a review of the environmental implications of mineral aggregate resources, Poulin and others (1994) identified two sources of aggregate materials: (1) sedimentary sand and gravel deposits, and (2) crushed bedrock. Such a ca- tegorization omits another important source of sand- and gravel-sized material, that is, weathered bedrock.

Crushed rock sand (CRS), industrial by-products (IBP) and recycled fine aggregates (RFA) are different types of alternative fine aggregates. The economic, sustainability and social benefits increases utilizing into concrete.

Aggregates are a broad category of construction materials. In terms of tonnage and number of quarries and mines world-wide, aggregates represent the largest mineral production tonnage excluding energy minerals. Range of grain/rock sizes. Concrete sand and asphalt sand have a grain size of 4.75 mm (0.18 inch) to 0.075mm (0.003 inch).

M-sand is crushed aggregates produced from hard granite stone which is cubically shaped with grounded edges, washed and graded with consistency to be used as a substitute of river sand. Leading architects and engineers recommend. India's most advanced sand. Building material must be free from traces of human body or animal.

According to the four test schemes in section 1.2, igneous rock aggregate and SBS modified asphalt are compounded to study the stripping rate of SBS modified asphalt on the surface of moderately weathered igneous rock aggregate under different boiling time and different anti stripping measures. The test results are shown in Table 4.
