摘要
Asphaltic concrete surfaces are protected from undesirable changes by applying a composition comprising a diorganopolysiloxane containing rod- shaped styrene-n-butyl acrylate copolymers which are obtained from the free-radical copolymerization of said monomers in the presence of the diorganopolysiloxane onto an asphaltic concrete surface and thereafter crosslinking the diorganopolysiloxane composition to form an elastomeric coating thereon. The asphaltic concrete surface may be coated with a primer prior to the application of the crosslinkable diorganopolysiloxane composition in order to improve the adhesion of the resultant crosslinked elastomer containing the rod-shaped copolymers. These asphaltic concrete coatings are especially useful in, for example, hydraulic engineering.
