Seal coating asphalt driveways, parking lots, and other paved areas is the process of applying a liquid product over an existing asphalt pavement in a manner that seals the surface and fills small voids and cracks as protection against the elements. Left unsealed, sunlight, wind, and water will gradually cause asphalt to harden and oxidize, and as it becomes more brittle, cracking can occur.

CHAPTER Chipseal Selection

coat seal or prime coat under the hot mix should be used with caution. The bitumen in a first coat seal will heat up when hot mix is applied to it, and then may migrate up into the thin layers of asphalt. This bitumen can saturate the mix (decreasing the % of air voids) leading to shoving and rutting (defects which are explained in Section 3.11).


Elastomeric coating is an above-grade exterior wall or roof coating that is approximately 10 times thicker than paint. It forms an incredibly thick yet flexible coating that helps waterproof the exterior of a structure. Unlike other types of coatings or paints, it can bridge hairline cracks to complete an airtight waterproof seal.

The refinery was never built but VDOT has stayed with emulsified asphalts (asphalt cement liquefied by suspending it in water) for surface treatment (chip seal), slurry seal, tack and prime applications ever since. Is a prime coat necessary? At one time it was thought that a prime coat was an essential element of good pavement construction.


The discussion of pros and cons between coal tar-based and asphalt-based seal coat materials is once again the hot topic within the industry. We find ourselves debating long-held industry tradition and a deserved feeling of "it it's not broke don't fix it" with the reality that technologies exist that can actually improve on a good thing.


In a chip seal road, a thin layer of asphalt is laid down before layers of crushed stone and aggregate are compacted on top of the asphalt. Chip seal is also known as macadam, named for a Scottish pioneer for paved roads. The engineer John McAdam invented the revolutionary crushed stone layer roads with binders in the early 1800s.
