Surface dressing also known as Tar and Chip is a traditional surfacing method and our specialty here at Norfolk premium driveways which involves spraying hot K170 bitumen emulsion or Polymer modified k190 bitumen, via tanker spray unit directly over a deteriorated asphalt concrete or road plain surface. Then, either washed 6-10mm gravel or granite chippings are broadcast over the hot liquefied bitumen, forming a complete coat of aggregate. The newly laid surface is then consolidated with a steel drum roller the give it an eye catching finish.
