What is a soil compaction test? Soil compaction happens when soil particles are pressed together, reducing pore space between them. Heavily compacted soils contain few large pores, less total pore volume, and a greater density. In the construction of high-load structures such as dams, paved roadways, and construction projects that rely on the stability of embankments, soil compaction is used […]
Read MoreDynamic Cone Penetration (DCP) testing is used to measure the strength of in-situ soil and the thickness and location of subsurface soil layers. It is similar to CPT (cone penetration testing) in that a metal cone is advanced into the ground to continuously characterize soil behavior. In DCP, however, the cone is driven by a […]
Read MoreAssessing the level of compaction of sub-surface soils can be essential to designing and validating compaction, particularly those subject to transient or cycling loads, and the DCP test is a crucial method to achieve this. Let’s look at the example of roadways. If the soil beneath a roadway is not compacted sufficiently, then the cycling […]
