Abstract
Abstract Surfacing compositions are provided which comprise a mixture of mineral aggregate, the residuum of a bituminous emulsion and a silane of the formula R.sup.b -- R.sup.a -- Si -- X.sub.3 wherein (a) X represents halogen or alkoxy, (b) R a represents alkylene and (c) R b represents amino, aminoalkylene amino, gamma-glycidoxy, hydrocarbyl, acyloxy or mercapto.
