What is the difference between micro surfacing and slurry seal?
The major difference between slurry seal and microsurfacing is in how they “break” or harden. Slurry relies on evaporation of the water in the asphalt emulsion. The asphalt emulsion used in microsurfacing contains chemical additives that allow it to break without relying on the sun or heat for evaporation to occur.
How much does surface treatment cost?
Cost: $4 per square yard ($70,400 per mile) A surface treatment in which the pavement is sprayed with asphalt and then covered with aggregate and rolled. Chip seals are used primarily to seal the surface of a pavement with non load-associated cracks and to improve surface friction on low volume streets.
What is blacktop slurry?
A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. The placement of this mixture on existing pavement is the “seal” as it is intended to seal the pavement surface.
When did Valley Slurry seal company start making emulsion?
For over 50 years now the name Valley Slurry Seal Company has been synonymous with high-quality asphalt emulsion applications. In 1978, VSS established its first emulsion plant in Redding under the name of “Morgan Emultech” and began to build it into the premier West Cost emulsion Company.
What makes up the Slurry seal on asphalt?
Slurry seal is a cold mix coating consisting of fine crushed aggregate, emulsified asphalt, additives and water applied to roadways. Emulsion serves as a binder to hold the aggregate together and to adhere to the roadway. It is a very economical way to maintain asphalt roadways but has no structural value.
How long can Slurry seal be used for?
Slurry seal is very economical and extends the life of pavement up to 7 years. It’s a no-brainer to use it to keep your parking lot, driveway, or roadway in great condition and looking great for years. There’s just one catch. Slurry seal is used to correct minor defects only.
How is a Slurry seal different from a seal coat?
It is not the same as seal coat and was developed in the 1930’s in Germany. Slurry seal is a cold mix coating consisting of fine crushed aggregate, emulsified asphalt, additives and water applied to roadways. Emulsion serves as a binder to hold the aggregate together and to adhere to the roadway.
