Microwave Road Repairs

An Auckland company is using microwave technology to repair tarseal roads.

The microwave pavement heating unit is mounted on a truck that travels at a very slow 75-600 mm per minute. The unit heats the road surface and the tarseal patching. This produces a hot bond that is water-resistant, making the patch last longer.
