DYNAMIC CONE PENETRATION TEST APPARATUS (DCPT) FOR PAVEMENT

DYNAMIC CONE PENETRATION TEST APPARATUS (DCPT) ASTM D6951

Model Number : TM-2101

The Dynamic Cone Penetrometer (DCP) test is used to assess the structural properties of soil, granular materials, and pavement layers by measuring the rate of penetration of a cone under repeated impacts. As per ASTM D6951, IRC:SP:72


Compliance with following International Standards:
ASTM D6951

Applications:
The Dynamic Cone Penetrometer (DCP) is an instrument designed for the rapid in-situ measurement of the structural properties of existing road pavements constructed with unbound material. 

Features:
  • Well proven, robust design
  • Portable and easy to operate
  • Tests can be carried out in minutes
  • Results correlate well with conventional CBR readings
  • Detects layer boundaries and thicknesses
  • Ideal in locations where access is difficult (such as coal holes)

Equipment detail:
The 8 kg free fall hammer is lifted and dropped through a height of 575mm. The distance of penetration of the cone tip is then recorded and the cycle repeated. Continuous measurements can be made down to a depth of approximately 850mm or when extension shafts are fitted to a maximum recommended depth of 2 meters. Where sub-pavement layers have different strengths, the boundaries can be identified and the thickness determined.
