This remark attributed to Henry Ford might well be used to describe the asphalt materials which are chosen to surface the majority of roads and other paved areas despite the fact that eventually under traffic and weathering the natural colour of the In preparing these products asphalt cement is mixed with either a petroleum diluent to produce cutback asphalt or with emulsifiers water and sometimes petroleum diluent to produce emulsified asphalt Once the liquefied asphalt cement is applied durin Research Project 0-6615.
