The surface dressing process is as follows:

• Clean and dry road is sprayed with appropriate rate of bitumen binder
• High quality stone chippings of the appropriate size are spread
• The surface is rolled ideally with Pneumatic tyred, multi-wheeled rollers to embed the chippings
• Traffic use road at reduced speed
• Road back swept to remove any loose stone chippings

Reasons for Surface Dressing

• To seal the road surface against ingress of water
• To arrest the deterioration of the road surface
• To provide a skid resistant road surface with the resultant benefits of reduction in accidents
• To reduce spray

Due to the properties of Bitumen successful surface dressing requires warm dry weather, and as a result work is carried out from May to July.
