Developed by the Army Corps of Engineers, Dynamic Cone 透度计 (DCPs) provide a low-cost, efficient test method for quickly determining in-situ CBR values of pavement base, 分基和分等级. DCPs are primarily used to determine in-place soil shear strength in road construction with CBR values from less than 0.5 to 100% 和 bearing values ranging from 430 to 10,800 psf. They can readily be used for depths from 30 inches to 6 foot with optional drive rods 和 extensions. All 洪堡 DCPs comply with ASTM D6951 specifications 和 come with a chart to compute CBR values, as well as an Excel spreadsheet template, which automatically charts the test results.
洪堡's DCPs are known for their high quality manufacturing 和 reliability, 和, are available with either threaded connections or a quick-connect design. Both 洪堡 DCPs feature our exclusive easy-grip hammer that provides a finger grip machined into the back side of the hammer flange, 这就提供了, non-slip lifting when performing a test.
洪堡 DCPs consist of a drive hammer 和 steel extension shaft assembly with a 60° hardened cone tip attached at one end. The cone tip is driven into the pavement or sub grade by means of a sliding dual-mass hammer. The diameter at the base of the cone is 20 millimeters, which is 8 millimeters larger than that of the extension shaft. 洪堡 DCPs can also quickly convert to a single- mass unit f或使用 in weaker soils having low CBR values or foundation evaluations by removing the outer sleeve from the dual-mass hammer.
