Learn about the benefits of Conventional Slurry Seal Treatments
Similar to healthy living, taking preventative measures is of the upmost importance for the longevity of roadways. One of the most common pavement preservation methods is a conventional slurry seal, which is a mixture of asphalt emulsion, aggregate, mineral filler, water and other additives accurately proportioned, mixed and uniformly spread over a properly prepared surface.
At an average cost of $2.50 per square yard, conventional slurry seals allow for a life extension of roughly 5-7 years for a quarter to a third of the cost of major road reconstruction. In addition, the seal prevents moisture and air intrusion in the pavement and improves skid resistance.
Conventional slurry seals are most often used on state highways, rural roads, county roads and even airport runways due to their high friction coefficient.
Conventional slurry seals are not recommended where ruts are greater than ⅜” or unsealed cracks of a ¼” are present.
Conventional slurry seals are less expensive, more convenient for travelers, require less time and are also eco-friendly. According to a study performed by BASF Corporation on the environmental impact of slurry seals, they are less harmful than other methods like hot asphalt mix.
- Use a prepared mix design.
- Clean pavement prior to applying seal.
- Patch and level as needed.
- Seal cracks ¼” or greater.
- Calibrate mix paver to ensure proper mix.
- Ensure the mix consistency is neither too dry nor contains excessive liquid.
- Control traffic until sufficiently cured.
