Experimental Investigation On The Strain Of The Reinforced Concrete Deck And Asphalt Concrete Pavement

This thesis elaborated on the basic concept, characteristic and the development of usage ofdeck pavement in domestic and foreign country, as an important part of bridge structure.Integrated with the problems which have encountered in the deck pavement, the reasons of itsdestruction and the problem of quality are detailed discussed.In this thesis, behavior of steel and reinforced concrete bridges are summarized first. Thenthe unique characteristic of deck pavement different from ecumenical road pavement isanalyzed. Thereafter, the inner strain test of the cement concrete deck asphalt concretepavement is constructed pertinently.The inner strain of cement concrete deck asphalt concrete pavement is very difficult tomeasure through experiment because of several restricts. By combining experiment test withANSYS analysis, this paper proved that it is a feasible way to measure the inner strain ofcement concrete deck asphalt concrete pavement under normal operating conditions. And then,the behavior of C30+AC-13I and AC-20I+AC-13I is compared and analyzed under static-loadand dynamic-load. This is also the emphasis of this paper: first, two types of specimenC30+AC-13I and AC-20I+AC-13I are chosen, and gradation design was constructed ofAC-13I and AC-20I one and another. The inner strains of two kinds of mixture understatic-load and dynamic-load are measured by use of strain gages, and then series ofconclusions are summarized. At last, proposal is suggested for the further research of theinner strain of cement concrete deck asphalt concrete pavement henceforth.
