What We Do Best
Asphalt-Rubber Chip & Cape Seals are comprised of Asphalt-Rubber binder spray applied at the rate of 0.55 to 0.65 gallons per square yard. Homogenously sized 3/8” aggregate is spread over the Asphalt-Rubber binder at the rate of 28 to 32 lbs. per square yard, followed by rollers that imbed the aggregate into the binder. The road’s surface is swept almost immediately to pick up any excess loose aggregate. In non-residential applications the Asphalt-Rubber Chip Seal is often fogged with a diluted emulsified asphalt to further lock in the chip. For residential applications, a Type II Slurry Seal is placed over the top to smooth out the surface texture. When a Type II Slurry Seal is put on top of the Asphalt-Rubber Chip Seal it is referred to as an Asphalt-Rubber Cape Seal. Both Asphalt-Rubber Chip Seals and Asphalt-Rubber Cape Seals offer long life (12-15 years) at an economical cost on roads that have alligator cracks in the 3/8” to 1/2″ range. The generously applied Asphalt-Rubber binder is flexible and is resistant to both aging and age-induced cracking. The Asphalt-Rubber membrane also seals off the road’s surface from top-down water penetration, keeping water out of the base. In Southern California Asphalt-Rubber Chip and Cape Seals are commonly referred to as Asphalt-Rubber Aggregate Membranes (ARAM) in the Greenbook.
Micro Surfacing and Slurry Seals are cost-effective preservation treatments used to maintain and extend the service life of pavements and roadways. The International Slurry Seal Association defines a Slurry Seal as “placed at one stone’s width thick”.
Conventional chip seals consist of a spray application of polymer modified asphalt emulsion followed by a layer of cover aggregate. In a double chip seal application, two layers of asphalt emulsion and two layers of cover aggregate are applied. The treatment is used to seal the existing pavement, protecting the existing surface from traffic wear and water intrusion.
Fog seal is a single application that can be used in conjunction with chip seals when the chip seal is the final surface treatment, application is typically light, made up of emulsified asphalt sprayed onto the chip seal or to an existing asphalt surface. This type of maintenance treatment will renew weathered (oxidized) asphalt surfaces and improve the surface appearance, and inhibit raveling. Sanding the fog immediately after application will reduce tackiness and allow for quicker opening to traffic.
