The wearing course of an asphalt pavement is compacted to density of 2.395 g/cm3 using 5.5% asphalt content by weight of total mix and specific gravity =1.04. Assuming that the absorbed asphalt equal to 0.8%by the weight of aggregate, and the bulk specific gravity of the aggregate is 2.66, determine if the compacted pavement is suitable for durability requirement or not?
A highway of 85 Km length, it is required to be paved by 4 cm wearing course. The width of this highway is 12 m. For requirement of the asphalt concrete mix plant manager, determine the quantity by weight for each type of aggregate and asphalt if the specific gravity of asphalt concrete mixture is 2.35 and the optimum asphalt content = 5.3%? • Details of aggregates Sieve Size (in) % Passing by Weight % Retained 3/4 100 0 1/2 95 5 3/8 83 12 1/4 59 24 No. 4 43 16 No. 30 13 30 No. 200 7 6 Pan 7
