Eight piles were tested using the maintained load (ML) test, Texas Quick (TQ) test and the constant rate of penetration (CRP) test. The results were compared on the basis of maximum load, load-settlement relationships, and load transfer behavior. Three piles were driven in sand, three piles were driven in clay, and two piles were driven in stratified deposits. One of the piles in sand and one of the piles in clay were instrumented steel pipe piles. No significant difference in maximum load was observed for the three types of load tests. The load-settlement curves were essentially the same up to about 60 percent of the maximum load. Above 60 percent of the maximum load, greater deformations at the same load were observed for the TQ test than for the CRP test. Even greater deformations were observed for the ML test. The center of load in the pile was at the shallowest depth for the CRP test and was observed to be successively lower for the TQ test and the ML test. /FHWA/
