• Abstract:
  The process of waiting for concrete to attain its desired strength for certain construction applications can pose one of two problems. The concrete strength may be overestimated, which creates a safety concern for workers and the general public. The concrete strength may also be underestimated, which incurs extensive costs because of delays due to the curing of the concrete. The maturity method takes into account the combined effects of temperature and time on the curing of concrete. Furthermore, when used in concert with accepted ASTM standards, the maturity method serves as a tool to determine when the desired strength is achieved so that appropriate testing can be carried out at that time. This investigation evaluated the maturity method for use in Maryland pavement applications and provides guidelines for its use.
