Asphalt Binders and Mixtures

Asphalt binders are subsidiary products procured during the refining process of petroleum while manufacturing gasoline, diesel, and similar petroleum products. Asphalt binders are obtained from the residue that remains after the distillation of petroleum, this residue is further subjected to steam distillation and oxidation to remove the traces of gas oil present in the residue. Certain additives or modifiers are also added to asphalt binders to alter them to suit different applications.

2. What is your recommendation for the maximum size of coarse aggregate for the following situation? A continuously reinforced concrete pavement cross section contains a layer of No. 6 reinforcing bars at 6-inch centers, such that the steel is just above mid-depth of a 10-inch thick slab. Cover over the top of the steel is therefore about 4 inches.
In proportioning a concrete mix, the coarse and fine aggregates had the following properties respectively; Coarse: Dry weight: 800lb, 3,2% MC, 2.0% AC, Fine: Dry weight 350 lb, 1.2% MC, 2.9% AC. How much should the water be adjusted to account for the agregate moisture?
