Abstract
In the present study, limestone (famous as Kota stone) mining waste reformed into aggregates of size between 19 mm and 0.075 mm were used to make bituminous concrete (BC) and dense bituminous macadam (DBM) by replacing conventional (Basalt) aggregates. Properties of LSW as aggregates was evaluated on the basis of physical parameters and mix performance. The mixes were evaluated on the basis of strength, durability, resistance to moisture and rutting. Results indicated suitability of LSA (Kota stone aggregates) as pavement material. Up to 50% replacement of conventional stone (CS) by LSA in BC mixes and 25% in DBM gave satisfactory results for moisture susceptibility, resistance to rutting and low temperature cracking. It was recommended to use LSA for making medium to low traffic roads.
