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.

The static level of water table in an unconfined aquifer was 30 m above the underlying impermeablestratum. A 150 mm diameter well, penetrating the aquifer to its full depth, was pumped at the rate of20 liters per second. After several weeks of pumping, the drawdown in observation wells 20 m and 50m from the well were 3.5 m and 2 m respectively, and the observed drawdowns were increasing veryslowly (B.Sc., DU, 2012).a) Assuming equilibrium conditions, estimate the hydraulic conductivity and transmissivity of theaquifer.b) Estimate the drawdown just outside the pumped well.c) What will be the yield of a 300 mm diameter well which will produce the same drawdowns justoutside the well and at the 50 m distance observation well in (2)? What would be the drawdown at anearer observation well?
