Abstract


With the development of modern transportation of highway asphalt pavement early damage is very widespread, serious impact on pavement life . The reason , in addition to the unreasonable design of the pavement structure , mainly pavement structural design , materials, design and construction of the three -phase bridge the gap between traditional asphalt pavement in the implementation process , and , especially in the design and construction of pavement materials failed to achieve one of control and management is not adequately reflected in the construction , design ideas based on the use of the properties of the material . Therefore, to make the life of asphalt pavement material design and construction of integrated research has important practical significance for the mitigation of the asphalt pavement diseases , improve the pavement quality . In order to solve the problem of highway pavement material gap between design and construction , architecture based the pavement PCI0 design and construction of integrated research ideas . Basis meaning of PCI0 , analysis the definition and impact factors of the full life of asphalt pavement PCI0 explore the relationship PCI0 material design , construction and integration ; according to Tosi - copper highway engineering , pavement layers bit division of , respectively the top layer in the surface layer based on low temperature performance , based on high-temperature performance , the following layer based on the fatigue properties of structural layer materials design and construction integration level judge based on the integration of design and construction of the mechanical properties of materials , as well as semi-rigid base . Pavement structural layer materials design and construction of integrated implementation process , the establishment of integrated evaluation method based on pavement performance PCI0 the same time meet the integration requirements of the structural layer construction technology ; influencing factors analysis based PCI0 use the layer bit weighted theory PCI0 amended West - copper high-speed , and the West - copper high-speed life test Road and other sections of the structure layer materials design and construction integration based the PCI0 individual penalty points list were evaluated.
