Homework Work the following problems tonight: 15 … Macadam is a type of road construction pioneered by Scottish engineer John Loudon McAdam around 1820, in which crushed stone is placed in shallow, convex layers and compacted thoroughly. A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a cement or bituminous binder to keep dust and stones together. The me…

When it is expressed in the basic SI Unit of mass (kg/m 3 ), it is usually referred to as density, but when expressed in terms of weight (kN/m 3 ), it is usually referred to as unit weight. Density (kg/m3) = Mass (kg)/Volume (m3)
Webd = density of asphalt, kg/m 3 (lb/ft 3). K′ = conversion factor, 1000 kg/Mg (2000 lb/ton). θ = duration of test run, hr. (i) The volume (V) of asphalt charged shall be measured by any means accurate to within 10 percent. (ii) The density (d) of the asphalt shall be computed using the following equation: WebUnit weight of asphalt kg/m3:- Unit weight of Asphalt ranges from 2,200 to 2,400 kg/m³ (or approximately 138 to 150 pound per cubic foot). The higher the density of the asphalt, the more durable it is. In general practices, we used 2,400 kg/m³ as the density to give a conservative estimation.
