LIGHT-WEIGHT MANUAL DYNAMIC CONE PENETROMETERS
8 kg hammer, 57.5 cm. fall
Standard: ASTM D 6951-03
The TRL DCP (Dynamic Cone Penetrometer) is an instrument designed for the rapid insitu measurement of the structural properties of existing road pavements constructed with unbound materials. Continuous measurements can be made down to a depth of approximately 850 mm or when extension shafts are used to a recommended maximum depth of 2 m. Where pavement layers have different strengths the boundaries can be identified and the thickness of the layers determined. Correlation’s have been established in earlier work (Van Vuuren 1969, Kleyn and Van Heerden 1983, Smith and Pratt 1983) between measurements with the DCP and CBR (California Bearing Ratio) so that results can be interpreted and compared with CBR specifications for pavement design. A typical test takes only a few minutes and therefore the instrument provides a very effi cient method of obtaining information that would normally require the digging of test-pits.
Model 16-T0012/C DCP FEATURES:
• Portable, hand-operated equipment.
• To obtain a direct evaluation of the “in-situ” strength properties of road pavement layers: the DCP has been correlated with CBR (California Bearing Ratio - Kleyn 1975).
• Field calibration of a portable dynamic cone penetrometer was made to determine a penetration resistance relationship with the standard penetration resistance.
• The penetrometer has been found useful in the inspection of footing foundations and for light field exploration where the standard penetration range of limits is generally known
• One year warrantee against any manufacturing defects.
