Asphalt seal-coat treatments are mainly a preventive maintenance procedure applied to the asphalt pavement surface to prevent or delay costly corrective measures (figure 2) Asphalt seal coats are surface treatments designed to seal and protect the asphalt pavement from harmful environmental conditions such as sunlight, rain, and snow.
Section 2: Functions of Surface Treatments and Seal Coats Anchor: #i1000132 General A surface treatment is placed on a crushed stone base to provide a roadway with the least expensive permanent type of bituminous surface It seals and protects the base and provides strength at the road surface so that the base can resist the abrasive and.
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 courseBSTs can provide all of the following: A waterproof layer to protect the underlying pavement.
Liquid Road is a polymer-modified, fiber reinforced asphalt emulsion coating that is job-mixed with specially graded aggregate and applied to the pavement surface The result is a highly durable, slip-resistant surface treatment that greatly extends pavement service life.
(See figure 12) The grooves increase pavement macrotexture, providing a path for bulk water drainage Grooving is a surface treatment that can be used when it is undesirable to apply any topical treatment to the pavement surface (eg, bituminous surface treatments) or to remove any of the pavement surface (eg, milling or diamond grinding).
A double bituminous surface treatment is a method of pavement construction that involves two separate applications of asphalt binder material and mineral aggregate on a prepared surface Double bituminous surface treatments are used for surfacing roads and streets, parking areas, open storage areas, and airfield shoulders and overruns.

Surface treatments may be applied to the base course of a new road or to the surface of an old road as a method of repair Surface treatments are grouped into three categories: sprayed asphalt, sprayed asphalt with cover aggregates, and asphalt-aggregate mixtur Sprayed Asphalt Surface Treatment Sprayed asphalt treatments contain no aggregat.
Sep 03, 2015· Finley crews applied Liquid Road Bituminous Surface Treatment at the Gunston Cove HOA in Lorton, VA.
The use of bituminous surface treatment (BST) as a road surface is a technique commonly accepted and understood by most provincial and territorial highways departments, but for the average engineer or municipality, it may be nothing more than the squirting of some oil on a road surface and covering.
The freeze-thaw cycle in cold climates will dramatically accelerate pavement deterioration, once water can penetrate the surface If the road is still structurally sound, a bituminous surface treatment, such as a chipseal or surface dressing can prolong the life of the road at low cost.
Surface Treatments In addition to the previously mentioned type of plant mix asphalt pavement or black top, there is another type of pavement performed by our company called Surface Treatment, also known as “tar and chip” or “chipseal” This type of road surface is used by VDOT on secondary roads that do not have a high traffic volume.
