Abstract:

Non-destructive test is the best method for evaluate the different parameters of the pavements. In destructive testing taking core or make destruction to the pavement is time consuming. And difficult to carried out in heavy traffic area. Non-destructive test are carried out on various pavement to determine the test parameters. Modulus of Elasticity, Poissons’s ratio and deflections of pavements are evaluated by using NDT instrument. Determination of strength of pavement and revised loading criteria for design of pavement. Test equipment use for to carry test on rigid pavement is Rebound Hammer and for flexible pavement is Falling weight Deflectometer. Test data collected from the tests for various pavement is used to evaluate, maintain and upgrade existing pavement systems to meet today's traffic demand for higher magnitudes of loading and frequencies.
