Title:
HOT APPLIED TACK COAT
Document Type and Number:
WIPO Patent Application WO/2011/106562
Kind Code:
A3
Abstract:
A method of applying building a pavement structure using a polymer modified hot- applied tack coat is disclosed. This polymer modified tack coat is non-adhesive at ambient temperatures, and, thus, also non tracking. The tack is applied while hot, but cools quickly. The subsequent application of hot mix asphalt results in a superior bond between the asphalt layer and the tack layer. It is particularly well suited to bonded friction course applications since it removes the necessity of specialized spray paving machinery and allows the use of conventional asphalt distributors and pavers.
