Paper Abstract

A kind of detection method based on principle of cone penetration test is put forward in order to rapidly get synthetical factors and section distribution curves of strength of the roadbed layer which is being measured. An on-vehicle roadbed strength testing equipment with this method is developed successfully. A computer controls the detection process and completes the data processing automatically. By the high speed of detection, online detection can be reached easily, therefore the entire course of construction of roadbed of highway and railway can be supervised to make sure quality of construction. It is proved by industrial experiment that the testing results reflect the reality of detected roadbed and potential quality problem under the surface of roadbed can be found quickly by the section distribution curve of strength of the roadbed layer. The testing equipment has passed through the technical appraisement organized by Railway Ministry.
