Period #14 Notes: BITUMINOUS MATERIALS (I)

While asphalt is essentially a product of petroleum, tar is a product that derives from distillation of coal. While coal tar was once quite commonly used as a binder in paving materials, it used less often now for a number of reasons: 1. It ages/oxides more rapidly than asphalt does, hence its service lifetime is shorter.
