SC-70,SC-250,and SC-800 Road Oils

Liquid asphalts are a mixture of asphalt and diluent to promote penetration.

The advantage of liquid asphalts are a resilient wear surface. Excellent water shedding ability and erosion control. The ability to be applied to existing soils, or for longer lasting results to base rock. Roads and adjoining areas should be graded to promote water drainage. Compaction is recommended, especially when heavier traffic is expected. A few hours prior to application, watering the road bed to promote permeability is recommended. However any standing water on the surface will produce negative results.

With the current situation of crude oil asphalts tend to cost more per application and cost less in the long run.
