Comparison between New RCC Structure (Bridge) and Old RCC Structure (Bridge) By Using Load Tests and NDT Tests

Abstract

Now a days, cement concrete plays a major role in constriction industries in which strength of concrete is given the at most importance. There will be depreciation in strength increases which leads to spalling of concrete. The spallings of concrete means leads to the reduction of the strength. In this case study, an old bridge & new bridge constructed in the same location are assessed. The load tests and NDT tests were conducted on new bridge pile foundations, where as NDT tests were conducted on old bridge and new bridge. After assessments if proper measures values were not achieved then accidents will be inevitable. Using this load tests and NDT tests we find out strength of concrete, finding cracks and voids, settlement ect. So these load tests and NDT tests is lowing the broad sense to refer the material of concrete and examined also. The load tests & NDT tests are carried out on new bridge, NDT tests were conducted on old bridge which are located at NH-16 (old NH-5) Ch.655+573. The type of load tests is vertical load test, lateral load test, dynamic load test, integrity testing is done on pile foundation and the NDT test are done i.e. Ultrasonic Pulse Velocity (UPV) test, Rebound hammer test, core cutter test, profometer test on various components of New and old Bridge. My ultimate aim is the comparison between new and old bridges by using load test and NDT test
