Alternatively a hot bitumen Chip and Spray can also be used. The procedure of application is the same except that hot bitumen spray equipment is needed. If applied within 24 hours of the stabilization priming is not necessary. One or more layers can be applied.
Typical application rates are:
• Chipped Stone from 20 to 40 kg per m2 per layer
• Bitumen from 5 to 15 litres per m2 per layer
Chip and spray options are very fast to construct, require minimum skill are durable and cost effective solution for surfacing of roads.
