Bituminous Surface Treatments - Pavement Interactive

A bituminous surface treatment (BST), also known as a seal coat or chip seal, is a thin protective wearing surface that is applied to a pavement or base course. BSTs can provide all of the following: A waterproof layer to protect the underlying pavement. Increased skid resistance. A filler for existing cracks or raveled surfaces.

HOT MIX ASPHALT PAVEMENT DESIGN GUIDE

A tack coat of asphalt (usually emulsified asphalt) is applied to ensure bond between the existing surface and the asphalt overlay. It should be applied in an even,thin coat at a rate of application of .05 gallons per square yard with a tolerance of.01 gallons per square yard. Excessive tack coat can cause slippage or can flush to the surface.
