In concrete pavement, it was found by the CCAA (2012) that the free silica limit used in the selection of natural sand to provide good skid and abrasion resistance to concrete pavement does not necessarily apply to manufactured sands. A sand durability test, based on the Micro-Deval abrasion test method, has been found to be effective in

Manufactured sand provides an opportunity to control the particles'' mineral content, in contrast to natural sand, which often contains undesirable minerals and clays whose effects on concrete quality can be very harmful. Another reason for using manufactured sand is the growing shortage of natural sand.

The manufactured sand has required gradation of fines, physical properties such as shape, smooth surface textures and consistency which makes it the best sand suitable for construction. These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary.
