Resurfacing a road is like maintaining your house. If you don’t regularly repaint your house the sun, wind and rain will damage the structure and you will need to make repairs.
The environment oxidises the bitumen in the road and can cause it to become brittle and crack. This lets water into the base layers of the road which leads to the gradual formation of potholes.
The constant flow of traffic on a road wears the surface down and packs it smooth. This smooth surface can be slippery during periods of rain. This is most evident when slowing approaching intersections and roundabouts or when taking bends on roads.
Traffic noise increases with the increase of traffic volume and types of traffic using the roads. Resurfacing can reduce the noise generated from a road.
Other issues that can be addressed in the resurfacing process are:
- An improvement in ride quality from patching
- Removal of an old linemarking scheme
- Removal of glare on rural roads
The two key improvements when resurfacing works are carried out are waterproofing the road (pavement life extension) and improving skid resistance (motorist safety). With the selection of a specific treatment, traffic noise from the road surface can be reduced.
