Cape Seal Roadway Surfacing Treatments
Equipping you to apply soil stabilization and modification treatments with confidence & success.
General Parameters & Advice
Since cape seal is a combination treatment and due to the fact that the bottom layer is a chip seal treatment, the site selection for chip seals should govern. Chip seals are designed for application on pavements that have adequate structural capacity. If a pavement is displaying structural distress, a different treatment should be selected. If a pavement is experiencing active rutting and/or shoving, it is not a candidate for chip sealing.
Site Selection for Specific Distresses
Although Cape Seals are widely used in the preservation of good roads, the treatment may also be used to address specific pavement distresses early on. Thus solving pavement problems early and avoiding more invasive measures that may be required later on. For Cape Seals, we are looking for chip seal candidate roadways due to that being the primary treatment used to address the existing roadway surface distress.
LOSS OF FRICTION: cape seals increase the skid resistance of the roadway. If there is a roadway that has low friction numbers, a cape seal can increase those friction numbers due to the excellent friction numbers slurry seal or micro surfacing can give a roadway.
MINOR CRACKING/WATER INFILTRATION: chip seals address minor cracks, less than ¼ inch (0.6 cm). Remember that water is our number one enemy and anything we can do to keep the water out is good.
