This interim certificate covers the use of GB5 High Modulus Asphalt System when used as a base or surfacing pavement layer for light and heavy traffic loading situation on new or rehabilitated pavement in all areas of South Africa.GB5 High Modulus Asphalt System is a high-performance asphalt mix paved in a conventional manner. It consists of graded crushed aggregate Styrene-Butadiene-Styrene (SBS) modified bitumen filler and reclaimed asphalt (RA) up to 25%.
It is applied as a base or surface pavement layer (with due consideration given to expected functional properties such as macro texture/skid resistance as well as fatigue properties based on total pavement structure and expected traffic loading).
