Bituminous Products Guidelines & Documents Trevor Distin RPF May 2008

Background Best practice documents for design, construction & maintenance of roads are in a state of obsolescence Ascribed to loss/migration of skills from Public sector Form the basis of sound engineering practice aimed to optimise provision & maintenance of our road network Springboard for new entrants into the roads industry to benefit from decades of experience

Incisive action In response Sabita increased its investment in technology development to: –ensure the sustainability of the road building industry –stem erosion of skills from road authorities –ensure a well informed bituminous products materials industry
