Title: New cement concrete pavement technology in Meihe expressway in China
Abstract: Meihe expressway has been completed in two years constructions.It takes three months in cement concrete pavement,in which there are more than five new technologies applied:(1)broken stone bed course is constructed all the way as a constructive layer to solve the problem of different settlement in mountain terain.(2)priming oil,seal oil and stone chip are used together on top of base to improve washing-resistant capacity.(3)dowel bar inserted(DBI) technique is applied in every transverse joint,with which Meihe is the longest express way as so far.(4)high position and asymmetry continuous slip-from technique is used first time interior or abroad between cement concrete pavement and steel and steel fiber reinforced concrete deck.(5)zero position slip-form technique is applied first time interior to steel fiber reinforced concrete pavement in six tunnels,about 5843 meters.There are also some other new techniques used,such as too high temperature cement use in hot weahter.
