For 30 years the Barker family have paved their way through the Sydney region

Asphalt Machine Paving

Asphalt paving of carparks, roads and schools.

Maintenance

This includes the use of saw cutting, potholes/patching, removal of soil, tipping, excavation using bobcats and profiling machines and trenching.

Driveways

Driveways involve a process of prior excavation and removal of spoil. Then road base is carefully laid at a minimum thickness of 100mm to support a rock hard surface. This occurs prior to the asphalt being laid on top. The road base in then compacted with a two tonne Waker Nuseson double drum roller vibration. This road base is crucial to an asphalt job as it determines its longevity. 

After the road base is prepared a liquid bitumen is sprayed over the entire area. This will bond to the asphalt when laid. 

Finally, hot mix (~160 degrees celsius) is laid on top of the glue at an average thickness of 30-50 mm depending upon light or heavy vehicle traffic. This requires rolling, use of compaction machines and various hand tools to tidy up edges or hard to reach edges. 

Speed Humps

Speed humps involve laying asphalt over existing surfaces. 

Two Coat Seals

Two coat seal is a process of preparing a job the same as asphalt with use of road base. Then liquid bitumen is sprayed and a 10mm stone is applied evenly on top of the glue. This mixture is then rolled and compacted. The process is then repeated with a smaller stone which binds into the larger stone before one last roll. The completed work will have a 10% loose stone finish.
