Model: DCP-TRL
Standards: ASTM D6591
The DCP Dynamic Cone Penetration test has good relations with CBR and resilience modulus, thus can be used to evaluate the roadbase strength. Features quick, easy to operate, no limited to filed conditions. The DCP is developed by the TRL As per AASHTO standards, the DCP has below relations with CBR: CBR=405.3/PR1.259
Wherein the PR is the penetration rate(mm/strike times), CBR, %.
