Acrobat® Reader® The use of the CRCP deltaT model shares
similarities with the JPCP deltaT model. The section used to
describe the process is the LTPP GPS section in Illinois,
17_5020. This was constructed in May 1986. The CRCP thickness is
8.6 inches, and the PCC mix used a limestone aggregate. Several
of the following inputs can be directly obtained from the MEPDG
input file: The maximum temperature and maximum temperature
range can be obtained by running the design file and deriving
this input from the worksheet titled “Climate.” For the month of
May, the maximum temperature and maximum temperature range for
this location are 89.6 and 39.2 °F, respectively. Using these
inputs, the CRCP deltaT gradient can be calculated as -1.3214
°F/inch. For the slab thickness of
