We offer coatings solutions for every stage of the pavement lifecycle.
Fog and rejuvenating
Begin preservation when the quality is still high, with an index of 90 or above.
The PRS Pavement Coatings Company offers a range of fog and rejuvenating coatings,
and an expert team to recommend and apply them.
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
PRS's Pavement Coatings Company is becoming known for alternative pavement products
produced in tandem with our 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.
