【 摘 要 】

The study of possible use of a non-destructive method of testing, based on reflection and transmission of sound waves, for measuring thickness of asphalt and concrete layers, is presented. The described theory of response of multi-layer structures to low-energy point impact has been confirmed through measurements on samples and test section. It has been established that measurement of thickness of asphalt and concrete layers is possible, with limitations relating to testing temperature and differences in acoustic impedance of layers.
