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.

Research - Review of Hot Bituminous Surface Treatments in ...

27-2-2019· This report reviews the construction and performance of 11 hot bituminous surface treatment (HBST) projects installed between 2014 and 2017. The HBST used AC-15P binders and either 3/8” to No. 8 or 3/8” to No. 4 aggregates pre-coated with PG binder. The pre-coated chips are dropped onto the hot binder and rolled with a series of pneumatic rollers which are followed by a steel

Road surface - Wikipedia

Bituminous surface treatment (BST) or chipseal is used mainly on low-traffic roads, but also as a sealing coat to rejuvenate an asphalt concrete pavement. It generally consists of aggregate spread over a sprayed-on asphalt emulsion or cut-back asphalt cement. The aggregate is then embedded into the asphalt by rolling it, typically with a rubber-tired roller.
