One of the major causes of pavement failure is water within the pavement. To prevent pavement failure, the engineer needs to give due consideration for adequate drainage during the design. Another drainage issue is damage caused by frost heave and subsequent thaw. Among the damange caused by frost heave is the cost of repair and maintenance, possible restrictions on vehicle weight, and even complete closure of roadways.
Roadrain is the solution to problems associated with roadway drainage. By providing excellent drainage, Roadrain greatly extends the life of the roads and reduces maintenance costs. Plus, Roadrain is easy to install and readily available. It's engineered solution to improve drainage and/or reduce frost heave potential incorporates a compressive resistant, void-maintaining system in the pavement structure. Roadrain has great compressive stiffness to support traffic, rapid fluid transmission characteristics equivalent to a free-draining base, significant air void to provide a capillary break, and high tensile strength allowing for increased reinforcement and subgrade restraint.
