CPP and CPR techniques include slab stabilization, full- and partial-depth repair, dowel bar retrofit, cross stitching longitudinal cracks or joints, diamond grinding and joint and crack resealing.
[1] Due to rising oil prices, these methods are often less expensive than an asphalt overlay and last three times longer in addition to providing a greener, more sustainable solution.
The process can also be used to address faulting at joints or cracks, roughness, polished concrete surfaces exhibiting inadequate macrotexture, wheel path rutting, unacceptable noise levels, permanent upward slab warping and inadequate transverse slopes.
[5][6] Dowel bar retrofit (DBR) is a process that re-establishes load transfer capability on joints and cracks by installing epoxy-coated, round steel dowels into existing concrete pavement across transverse joints and/or cracks.
The entire road is often diamond ground to remove bumps or dips and provide a safe, quiet riding surface.
