Research And Application Of The Disposal Technology For Exposed-aggregate Cement Concrete Bridge Deck Pavement

With the cement concrete bridge deckpavement widely applied in the superhighway, how to improve its anti- slippery ability and anti- slip of durable is to a problem to be soluted urgently. There are lots of shortage in the traditional surface's handling construction methods .Those influenc the anti- slippery ability and anti- slip of durable of bridge deckpavement. The disposal technology for exposed-aggregate cement concrete bridge deckpavement as a kind of new construction method, is studied at home and abroad. Through the research on function of gathering and anticipating exposed-aggregate cement concrete deckpavement, it is proved that this method has excellent usage function. But there is something else studying on gather and anticipate exposed-aggregate cement concrete bridge deckpavement of technique request and construction craft characteristic and road deckpavement function evaluation,and there is nothing about systematic theory concerning gather and anticipate exposed-aggregate cement concrete road the deckpavement.In this paper,with spraying retarder to exposed-aggregate and measuring the resistance with instrument on cement concrete penetration, it is established the relation between penetration resistance and flushing.Through controling the magnitude of penetration resistance to flush, the problem of hard flush clear is solved. It supports the application on outside exposed a great area .As a result,it is well for using this method to carry on the instruction in the practical construction.
