Abstract


Crushed or ordered inert particles obtained from the materials that are used in road are known as recycled aggregates. The objective of this research is, to conclude and relate the maximum dry density, optimum moisture content and California Bearing Ratio (CBR) of Granular Sub Base (GSB) and Wet Mix Macadam (WMM) by means of different percentages of recycled aggregates. This study was carried out by using CBR for total of 5 batches of mixes prepared in which 0, 20, 30, 40, 50 and 60% are replaceable to that of fresh aggregate by recycled aggregate at optimum moisture contents. The maximum dry density of recycled aggregate was up to 30% and replacement level was about 0.02 g/cc. The CBR of recycled aggregate was up to 30% and replacement level was about 1.5%. The reduction of strength causes due to lower strength of recycled aggregate as in compare of the fresh aggregate.
