That's where slurry seal comes in. And while slurry seal has a cost, it is estimated that it is still almost 14 times cheaper than needing to replace your asphalt prematurely due to poor maintenance. Make the right decision and maintain your asphalt using slurry seal so you save long-term money, time, and stress.
The slurry seal mixture shall contain an emulsion content of 10 – 20% by weight of dry aggregate which shall be determined in the laboratory by an approved mix design process. The residual asphalt content shall be 5 – 15% based on weight of dry aggregate. Tests on CQS Emulsion Minimum Maximum Test Method
Slurry seal is a mixture of aggregate, asphalt emulsion, and filler, which are mixed together according to a laboratory's design-mix formula. water is also added for workability. Asphalt emulsions serve as a binder, holding the crushed aggregate together and adhering the new slurry surfacing to the old surface over which it is being applied.
