UCS P d= u (1) 4. Point Load Test The ASTM-D5731-08 [8] code gave a clear justification for the use of the point load test. The code started its justification by giving statements about the time and money spent on performing a UCS test and recommended the use of simpler in-situ tests of which the point load test was one of them.
