The Dynamic Cone Penetrometer – DCP – determines empirically the CBR% or California Bearing Ratio of soils of the road, without destroying the road structure. Very useful and fast test procedure to find the field CBR of road constructed using TerraZyme, enzyme based low cost eco friendly roads The procedure is very simple. The test is conducted by driving a cone shaped probe into the treated road by the impact of a 8 kg hammer (See diagram and dimensions in Appendix A and B). As the penetration in millimeters (mm) of the cone tip per drop is empirically correlated with CBR% values developed in the laboratory, the capacity or road bearing strength of the treated road is measured “in situ”. The lower the DCP penetration values, the denser or stiffer the soil is and the higher the CBR%. Download DCPT Test Manual

About us
Avijeet Agencies is the pioneer to get enzyme based road construction technology into India. We have successfully executed rural roads in India which have performed exceptionally well to tune of 300 km in PMGSY scheme. These roads have performed exceptionally well without any problems. The roads have been used in all soil and weather conditions, including all weather roads in Western Ghats receiving over 4000mm of rainfall. We have also constructed roads successfully in Black cotton soil. We help the clients with pavement designs and provide consultancy to the clients to ensure that the project is executed as per specifications laid down.
