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.
