The ASTM D2166 standard provides a streamlined laboratory procedure to measure the maximum axial compressive stress a cohesive soil specimen can withstand under zero confining pressure. It is specifically designed for soils like clays or cemented materials that possess enough cohesion to maintain their shape without lateral support. Why Perform the UCS Test? astm d2166 pdf
