• It is used to classify the soil, by its behavior, or reaction to the cone being forced through the soil. • High ratios generally indie clayey materials (high c, low Ø) while lower ratios are typical of sandy materials (or dry desiced clays). • Typical skin friction to tip friction ratios are 1% to 10%. The ratio seldom, if ever, exceeds 15 to 20%. Sands are generally identified ...

the chart is shown in terms of the corrected cone resistance qt, it can be used equally well with uncorrected cone resistance, qc, since the difference between qc and qt is small, except in soft fine grained soils, where qc < 1 MPa. The chart by Robertson et al (1986) uses the basic CPT measurements of qc and fs and has 12 soil types, whereas the chart by Robertson (1990) uses normalized ...

Cone penetration testing (CPT) is an insitu test that is used to identify the soil type. In this test a cone penetrometer is pushed into the ground at a standard rate and data are recorded at regular intervals during penetration. A cone penetration test rig pushes the steel cone vertically into the ground. The cone penetrometer is instrumented to measure penetration resistance at .

· Utility Sand: Also known as fill sand, utility sand is rather coarse in texture and is a mix of white, gray, beige, tan, and brown particles. It's typically used underneath paving stones (, as a base material for concrete) or even to fill holes and trenches. It compacts especially well, despite the fact that it's not processed or washed. Although utility sand isn't the type of .
