Nondestructive load testing was carried out to study the behavior of roller-compacted concrete (RCC) pavements located at Moran and Conley Terminals, Boston, Massachusetts. Tests were conducted in late October 1990 with a Dynatest 8081 heavy weight deflectometer. Loads were applied at various locations on each of the 11 selected test sections. Measured deflections were first used to estimate the in situ pavement parameters. The estimated values were then used, in conjunction with a concrete pavement analysis program, to evaluate the structural performances of the pavement sections. Also, load transfer efficiency across joints and cracks was evaluated, and laboratory tests were performed on cores taken from the pavements. From the study it was found that RCC generally possessed engineering properties similar to those of conventional concrete. However, the RCC modulus of elasticity appeared to be lower than that of portland cement concrete. Large variations in load transfer efficiency were observed. The structural performance of the RCC pavement test sections in the study appeared to be adequate.
