The dynamic Cone Penetration Instrument (DCP) is a lightweight and lightweight ground-soil in-situ test probe. with advantages of fast, simple, and free from site constraints. It is suitable for the evaluation of the bearing capacity of the construction site or the old roadbed. The dynamic conical penetration instrument can effectively overcome the shortcomings of sand filling, ring cutter, irrigation and electric earth borrower by quickly detecting the penetration degree of soil foundation. It is a new generation of ground-based compaction performance rapid detection equipment; There is a good correlation between the California Road Bearing Ratio (CBR) and the rebound modulus, which can be used to evaluate the strength of the subgrade.
The Power Cone Penetration Instrument (DCP) has accumulated the relationship between the penetration value and the corresponding soil index in foreign countries. Its penetration value has been related to the elastic modulus of soil, CBR, and unconfined compressive strength. In South Africa, the penetration value has been used as a parameter for pavement design.
