The disclosed retroreflective element includes a polymeric core that is loaded with a plurality of first beads and second beads distributed at the perimeter of the core. The first beads are different than the second beads. Because of the beads in the core, the retroreflective element remains useful for returning light even after portions of the core begins to wear away. Further, when the retroreflective elements get wet, water will settle to the bottom of the perimeter of the core. Therefore, using the second beads with a refractive index suited for wet conditions, while the first beads have a refractive index suited for dry conditions allows the retroreflective element to be useful in both wet and dry conditions even while the retroreflective element wears during use.

This invention, in embodiments, relates to non-asphaltic coatings for roofing materials, to roofing materials made therefrom and to methods of preparing such coatings and roofing materials. By blending thermoplastic polymers with appropriate fillers and/or recycled materials, a composition is produced that can be pressed into a desired shape, or that can be additionally mixed with oils, resins and/or waxes to provide a liquid that can be poured onto an appropriate substrate.

A method for generating a shingle roof coating is described. The method includes receiving an asphalt feedstock and separately proceeds to mix an elastomeric polymer and an asphalt flux to generate a first concentrate. The first concentrate is then heated separately from the asphalt feedstock. The method then mixes the first concentrate with the asphalt feedstock and heats the combined first concentrate and the asphalt feedstock to generate the shingle roof coating. The amount of elastomeric polymer in the first concentrate is adjusted based on the type of asphalt feedstock such that the resulting shingle roof coating includes 0.5% to 6% by weight of the elastomeric polymer.

An asphalt composition for use as a shingle roof coating is described. The asphalt composition includes a first asphalt feedstock and a first concentrate. The first concentrate includes an elastomeric polymer and an asphalt flux. The asphalt composition includes 0.5% to 6% by weight of the elastomeric polymer. The elastomeric polymer includes a styrenic block copolymer. The first concentrate includes 3% by weight to 25% by weight of the styrenic block copolymer. The first concentrate includes 3% by weight to 15% by weight of one of an ethylene polymer and an ethylene propylene copolymer. The first concentrate has a penetration of at least 100 dmm.
