Queensland Department of Transport and Main Roads via an infrastructure services provider Ventia, needed to remove the existing failing asphalt on Springbrook Road, a high trafficked tourist road set in a challenging mountainous terrain.
The existing pavement was worn, slippery and dangerous. The requirement was to replace the road with a durable high skid and fatigue resistance asphalt.
A small-stone Stone Mastic Asphalt (Carbonmastic 7mm) was modified using Entyr’s recovered carbon black (eCB) and created using tyre-derived hydrocarbon (eTDFO). In addition to the replacement criteria, the asphalt solution improved sheer road strength, increased colour duration, noise reduction and environmental benefits.
