Sealed Pavement Major Patching program

About this project

Our Major Patching program is developed annually to repair small-medium localised pavement failures across our sealed road network. These works are sometimes conducted one to two years in advance to prepare roads for routine resurfacing works or as identified to address isolated defects. Our Sealed Pavement Rehabilitation Program targets roads that have sections with numerous failures and significant roughness and require full-width reconstructions.

Why was this project undertaken?

The ‘pavement’ of a sealed road refers to the various layers of crushed rock, gravels and natural material which exist under the black sealed surface. This sandwich of compacted materials provides the structural base of the road that supports the traffic while the thin bitumen surface acts as the waterproofing layer to prevent the pavement from getting excessively wet and falling apart.

Over a road's life, traffic slowly breaks down the pavement materials until they can no longer support the traffic loads, which causes them to deform and ultimately fail.

What is the impact of these works?

These works helped create safer driving conditions by addressing a number of defects and improving the road surface.
