Learn MoreThe maximum unit weight is sometimes called the "solid density". This value is based on the asphalt mixture's maximum specific gravity – also known as the Rice value or G mm in Superpave. The maximum unit weight is determined by multiplying the Rice value by 62.4 pounds per cubic foot (PCF). For example, 2.500 is a typical Rice value. 2

Learn MoreThe mechanical rap asphalt mainly depends on the original type of asphalt pavement type, the degree of processing, and the method utilized to recover the material. A compacted unit weight of rap asphalt decreases with the increasing unit weight. The maximum dry density value recorded ranges from 1600 to 2000 kilogram per cubic meter.
Learn MoreBasic HMA weight-volume relationships are important to understand for both mix design and construction purposes. Fundamentally, mix design is meant to determine the volume of asphalt binder and aggregates necessary to produce a mixture with the desired properties (Roberts et al., 1996 [1]).). However, since weight measurements are typically much easier, they are typically taken then …
Learn MoreMaterials: Aggregate (crushed stone or gravel and manufactured sands), asphalt binder (with modifiers) Information: Open-graded HMA can be more expensive per ton than dense-graded HMA, but the unit weight of the mix when in-place is lower, which partially offsets the higher per-ton cost. The open gradation creates pores in the mix, which are
