Description
The asphalt interlayer that delays cracks.
The Strata® reflective crack relief system protects existing pavement structures from water damage and delays reflective cracking in new surfaces. It includes a highly flexible, impermeable hot mix asphalt interlayer and a recommendation for the hot mix asphalt overlay with improved binder technology.
One of the many problems facing today’s highway engineers is reflective cracking of hot mix overlays over concrete and composite pavements. The cracks lead to a much more serious problem as they allow moisture to infiltrate and deteriorate the underlying pavement structure. The result is loss of pavement structural strength and in some cases, a decrease in the pavement's rideability.
The innovative Strata system answers the need for protecting overlaid pavements. An impermeable interlayer prevents moisture from deteriorating existing pavements, delays reflective cracking in the overlay. Using conventional HMA equipment and procedures, Strata construction is faster and easier than other crack relief methods and rehabilitation, minimizing user delays. The Strata system extends paving dollars, while helping preserve the existing pavement structure.
