A method for applying a high friction surface roadway treatment and composition used therein is disclosed. The method comprises the steps of: providing a binder composition, comprising: 10-99.9 wt. % of a resin; 0.1-70 wt. % of an elastomer; heating the binder composition to a sufficient temperature to obtain a molten binder composition; applying a layer of the molten binder composition; and applying a layer comprising aggregate having a nominal maximum size of at least 1 mm, and an embedment depth of at least 30% in the molten binder composition layer. The resin is selected from hydrocarbon resins, alkyd resins, rosin resins, rosin esters, and combinations thereof.

A coated rubber composition includes a rubber composition coated with a liquid refresh agent selected from the group consisting of one or more liquid terpenes, limonene, carvone, pinene, pine needle oil, citral, orange oil, C.sub.9-C.sub.15 aliphatics, C.sub.9-C.sub.15 cycloaliphatics, ethyl lactate, dipentene, 1,8-cineole, eucalyptol, citronellol, geraniol, citronellene, terpinen-4-ol, and combinations thereof. A method of application and a coated rubber composition are also disclosed.

The present description provides esterified fatty acid and/or tall oil compositions and their use as alternative plasticizers in adhesives formulations. These esters demonstrate similar or improved performance over adhesives industry standard plasticizers. The description also provides methods of manufacturing and using the same, for example, to improve or modify the performance of adhesive materials, such as, hot melt pressure sensitive adhesives and hygienic adhesives.

The inventors have discovered hot melt adhesive compositions that can be formulated to have a high percentage of environmentally conscious components and still provide performance over a broad temperature range.

The invention features a hot melt adhesive composition including from 5% by weight to 50% by weight of a thermoplastic polymer, from 10% by weight to 80% by weight of a bio-based tackifying agent, and from 2% by weight to 50% by weight of an environmentally conscious aliphatic plasticizer having a cyclo-aliphatic content of no more than 2% by weight as tested by .sup.1H-NMR Spectroscopy.

Adhesive tapes are described which find particular application for sealing joints or regions between adjacent panels such as rigid foam insulation panels. Also described are methods of using the sealing tapes and systems of sealed panels using the sealing tapes.
