For the need of controlling the subgrade construction quality of Zhengzhou to Minquan Highway, a more systematic research of the application technology of using portable falling weight deflectometer （PFWD） in testing the silt subgrade modulus of elasticity is studied, and a comparative analysis with traditional bearing plate method is done. The research results show that using PFWD is able to achieve this goal： rapid non-de- structive testing and effective control of silt subgrade construction quality. PFWD is a lightweight, easy testing and alternative method, related research and development of this testing technology has an important role in guiding of efficient and accurate detection and evaluation of the subgrade construction quality.
