CP-2 is an extremely flexible base course that can be used for new construction of existing gravel roads or over existing, but severely deteriorated roadways. The material is designed to provide a flexible base course material on low ADT roads—roads where a rigid Hot Mix can not be successfully used.
The roadway is re-profiled by a paver placing #57 aggregate at an average depth of 2 inches, followed by penetrating the aggregate with 1.50 Gals/SY with a soft asphalt emulsion. An application of #8 aggregate is applied to choke in the #57s. Typically, a CP-2 Bituminous Binder Course is then followed by a Double Chip Seal which waterproofs the binder and provides an inexpensive flexible wearing surface.
The open textured base course allows water to pass laterally through the bottom layer of the CP-2 without fear of frost damage due to the high air void and asphalt content of the material. For this reason, it can be used for roadways which exhibit poor drainage.
