Abstract:
The maturity method was used as an in-place technique for the determination of compressive strength during the construction of a highway bridge at the intersection of Interstate-78 and state highway 21 in New Jersey. The objective was to demonstrate the feasibility for using the maturity method in future New Jersey Department of Transportation (NJDOT) projects. The 28-day cylinder strength did not closely represent the in-place concrete strength or include the effects of placement, and curing operations, and a more rapid procedure was needed to proceed with critical construction operations. This project served as a pilot for subsequent establishment of Departmental training and procedural operations for the construction of concrete structures.
