Cement Emulsified Asphalt Concrete Pavement Materials Research

The cement-emulsified asphalt is a wildly used material in roads construction and protection. Because influenced by the quality of the asphalt , it uasal causes some diseases of the roads surface. To sovle this problem, some abroad roads institutes applied a useful method thatadding cement into emulsified asphalt concrete , which improved the applacation fuctionroad in road of this material.This text primarily discussed the test method that adapt to the specification and ability of cement-emulsified asphalt concrete , it recommended the test method and adding in proper order that the fit admixtrue corrects Mstthus test furtherly , then , it brought up the best match of cement-emulsified asphalt concrete through the test, and explained the influence of heat stability with earlier period strength when adding a certain rate of cement into emulsified asphalt concrete , finally studied fisrt the strength of that material to become the principle with technique economy analysis.
