Let our experts recommend and apply the best seal for your road.
RAP slurries. Premixed sealcoats you can apply yourself. Fast-drying conventional slurries. Chip seals. We have a full range of solutions.
We offer coatings solutions for every stage of the pavement lifecycle.
Chip seals and cape seals.
If the pavement condition has deteriorated to an index of 55 or 60 and you can't afford major rehabilitation, laying down a chip seal (crushed rock on hot asphalt) may be the solution. To eliminate any problems with loose rock, we often recommend a cape seal, which is a chip seal combined with a slurry.
Slurry Seals: from fast-dry conventional Type I to Type III.
According to the International Slurry Surfacing Association (ISSA), the performance characteristics of a slurry mixture make an ideal preservation treatment for hot mix asphalt pavements. Materials used to create a slurry seal include aggregate (1/4-inch or smaller), asphalt emulsion, filler (Portland cement, hydrated lime or aluminum liquid serve as stabilizing agents), and water (for workability) mixed together according to a laboratory's design-mix formula.
The emulsion serves as the binder to hold the crushed aggregate together and adhere it to the old road surface. Various emulsions and aggregates are used to meet the conditions, specifications and requirements of individual projects.
Emulsion of varying composition and setting times are mixed with one of three grades of aggregates – Type I (fine), Type II (general), and Type III (coarse). Fine aggregate mixtures are used for maximum crack penetration and sealing in low-density/low-wear traffic areas.
Type II aggregates are used on moderate-to-heavy traffic roads to seal, correct moderate-to-severe raveling, rejuvenate oxidized surfaces, and improve skid resistance. Coarse aggregate slurry mixtures are used to correct severe surface conditions and improve skid resistance on roads with heavy traffic loads.
Alternative recycled pavement products.
Pavement Coatings Co. is known for alternative pavement products produced in tandem with Reclaimed Aggregates Inc, another PRS subsidiary. These products include:
- Rap-Seal, a RAP that has been compacted and resealed with a recycling emulsion
- ReRAP, a crushed and sized RAP product that has been mixed with an emulsion before being placed and compacted
- ReNew Pavement, a RAP that has been crushed and screened into individual sizes to be blended back into a mix design that meets a specified gradation band. Performance characteristics of ReNew Pavement are comparable to conventional hot mix produced with virgin materials.
