A 25 km long, 8.001 km wide, 2-lane highway is to be paved with 6.00cm thick layer of asphalt.A fleet of 4 dump trucks are to be employed each with an empty mass of 22metric tons and a carrying capacity of 26 cubic metres. Asphalt with a density of 2.322g/m^3 will be used. Determine a) The number of dump truck loads required b) If it takes 4 hours for each truck to deliver a load, how long in day and hours will it take the trucks to deliver all the asphalt? C) The gross mass of each truck.

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.
