A strike-off spreader box lays a uniform smooth mixture of slurry over an existing asphalt concrete pavement. A thin, hard, dense asphalt concrete paving surface results after curing of the asphalt. Slurry seal is applied in thin monolayer when the ambient temperature is above 50oF and when there is no danger of rain. Cold temperatures or wet conditions slow and sometimes stop the curing process. Slurry seal should be restricted to structurally sound pavements that are subjected to moderate volumes of traffic.
Slurry seal can fill small cracks in most pavements, but there are limitations.
Small surface cracks on sound pavements can be successfully treated. If cracks are due to an inadequate pavement structure or excessive pavement movement generally reflective cracks will eventually reappear. When properly designed and applied slurry seal will significantly extend the pavement life. Guideline specifications for the design of slurry seal are available from the International Slurry Surfacing Association. or contact Prime Materials. This method produces an all-weather surface, renews weathered pavements, improves skid resistance, lane demarcation and seals pavement.
