An asphalt base pressure-sensitive adhesive includes asphalt, an elastomer, residual pitch, as well as isoflour and optional oil and other inert fillers. The amount of elastomer is reduced by incorporating the residual pitch product which acts as an extender of the elastomer. Further, the isoflour further acts as an extender, and is compatible with the residual pitch. In a preferred embodiment, the pitch product is pine pitch.

A solid thermal balancing composite material with lightweight is formed by a reinforced composite material pressured by a molding machine after going through a powder filling equipment. The reinforced composite material is a mixture of inorganic filler powders and polymer adhesives after granulation. The specific gravity of the solid thermal balancing composite material is no greater than 2.0. In addition, the present invention is adjustable in different shapes for various applications of heat dissipation.

A pavement repair system is provided utilizing solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.

A partially hydrogenated block copolymer of the present invention includes: a polymer block (A) containing a vinyl aromatic monomer unit as a main component: and a polymer block (B) containing a conjugated diene monomer unit, wherein in a differential molecular weight distribution (B) of a degradation product of the partially hydrogenated block copolymer obtained by an ozone degradation method, a distribution of degree of hydrogenation H, which is given by a maximum peak height in a region of a molecular weight of 800 or more and 3,000 or less, is 0.01 to 0.5.

A roofing system includes a roofing membrane. The roofing membrane has a surface energy of 40 mN/m or less. The roofing system includes a roofing substrate. The roofing system includes an adhesive disposed between the roofing membrane and the roofing substrate. The adhesive includes a styrenic block copolymer. The styrenic block copolymer is present in an amount of 0.5 wt. % to 30 wt. % based on a total weight of the adhesive. The adhesive includes asphalt. The asphalt is present in an amount of 70 wt. % to 99.5 wt. % based on the total weight of the adhesive. A ratio of the styrenic block copolymer to the asphalt in the adhesive is 1:11 to 1:3.

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.
