CONE PENETROMETER TESTING (CPT) The Cone Penetrometer Test is a subsurface soil exploration method that involves pushing a conical-shaped probe into a soil deposit and recording the resistance of the soil to penetration. Test equipment consists of a cone assembly, a series of hollow sounding rods, a hydraulic frame to push the cone and rods into the soil, an electronic data processing unit, and a 20 ton truck to transport the test equipment and provide thrust resistance. The Caltrans CPT apparatus is a Hogentogler electric cone penetration testing System. All Testing is done in conformance with ASTM test method D5778-95. In a CPT test, output quantities for both tip resistance and sleeve friction are simultaneously recorded in units of tons per square foot per foot of depth. The data processing unit also calculates and records the ratio of friction resistance to tip resistance (generally referred to as the friction ratio). In addition, dissipation of excess pore water pressure or seismic shear wave velocities can be recorded at discrete depth locations during testing.

California Bearing Ratio The California Bearing Ratio (CBR) test is an empirical test first developed in California, USA, for estimating the bearing value of highway sub-bases and subgrades. The test follows a standard procedure and there is little difference between BS and ASTM tests. However, there are numerous ways of preparing samples and in this respect American practice differs in detail from British Standard practice. The test can be performed in the laboratory on prepared samples or in-situ on location. It is important to appreciate that this test, being of an empirical nature, is valid only for the application for which it was developed, i.e. the design of highway base thickness. ELE offer a complete range equipment for Laboratory or In-situ CBR testing which includes: • CBR-Test 50, 50kN capacity Load frame for laboratory testing • Accessories for force and penetration measurement • CBR Moulds and Accessories • Expansion (Swell) Test Equipment • In-situ CBR Apparatus with optional Conversion Frame for Laboratory testing The full range is detailed in our New, 10th edition Construction Materials Testing Equipment Catalogue.
