Product Description
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.
RSR Ranges
50-80
Product Materials
Latex modified asphalt emulsion and stone cover aggregate (3/8” to 1/2” depending on treatment)
Life Expectancy
- Single Chip Seal: 5-7 Years
- Double Chip Seal: 7-11 Years
Ideal Candidate
Chip Seals can be placed on low volume roads up to approximately 2,000 AADT. The treatment should be placed over sound structural pavement with a good profile. The pavement may be exhibiting minor to moderate surface distress (cracking, bleeding, raveling, oxidation).
Surface Preparation
Surface leveling and crack sealing should be completed as needed. Full depth patching may be required in areas of advanced deterioration. Structure adjustments, while not typically required, may be considered to damaged structures.
