Bituminous Materials

The word 'bituminous' in Bituminous materials come from the word bitumen, which is popularly known as 'asphalt' in the United States. Asphalt is a heavier substance that is obtained by the fractional distillation of crude oil, after removing the lighter components such as gasoline and diesel. Asphalts are known to have good adhesive and waterproofing properties. Depending upon the grade needed, asphalt may be refined several times in the fractional distillation column.
