Bibliography

Describes a mechanical cone penetration test (CPTM), including equipment requirements, execution and reporting. The results from such geotechnical testing are especially suited to the qualitative and/or quantitative determination of a soil profile - together with direct investigations - or as a relative comparison with other in situ tests.
