Hot applied tack coat
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.

METHODS AND APPARATUS FOR TREATING BITUMEN MIXTURES
Disclosed are methods for preparing a high-viscosity non-hazardous bitumen composition for transportation in a railcar, wherein the method may include: (a) providing to a fractionator system a low-viscosity bitumen composition previously residing in a pipeline having a first viscosity and comprising a miscible blend of hydrocarbons, which blend was prepared by mixing a first diluent composition with a first bitumen composition; (b) heating the low-viscosity bitumen composition in the fractionator system at an operating temperature of from 170 C to 232 C to provide a first light fraction and a first heavy fraction; (c) removing at least a portion of the first heavy fraction from the fractionator system, wherein the first heavy fraction has a second viscosity that is higher than the first viscosity; (d) forming a high-viscosity non-hazardous bitumen composition from at least a portion of the first heavy fraction; and (e) directing the high-viscosity non-hazardous bitumen composition to a railcar.

A SELF-ADHERING BITUMINOUS SEALING ELEMENT WITH IMPROVED BONDING AT LOW TEMPERATURES
A sealing element includes: a waterproofing adhesive layer having first and second major surfaces, an adhesive layer covering at least a portion of the first major surface of the waterproofing adhesive layer, and a carrier layer on the side of the waterproofing adhesive layer opposite to the side of the adhesive layer, wherein the waterproofing adhesive layer is composed of a self-adhering bituminous composition and the adhesive layer is composed of a non-bituminous pressure sensitive adhesive. The sealing element is used as a waterproofing, roofing, vapor barrier, vapor retarder, or a fa?ade membrane, or as a waterproofing, roofing tape, or fa?ade tape.
