This section defines the topmost, wear-resistant layers of the road. It addresses prime coats, tack coats, surface dressings, and asphalt concrete mixes. It dictates Marshall stability parameters, bitumen binder grades (such as 60/70 or 80/100 penetration grades), aggregate polished stone values, and laying temperatures. Material Engineering Standards
Includes over 1,150 definitions, contractor site establishment requirements, traffic accommodation, and environmental protection measures.
: Establishes standard terms for road infrastructure, such as the Road Reserve (expanded to 60 meters under the later Roads Act).
