PERFORMING THE TEMPERATURE CORRECTION
Before corrections to a reference temperature may be made, the pavement
temperatures you are correcting from must first be established. These pavement temperatures
are referred to herein as the base temperatures for the modulus correction and refer to the
pavement temperatures at which the FWD deflections were taken. There are two functions
available in MTCP to establish the base temperatures. One allows you to estimate the
pavement temperature at a given FWD station by interpolating between pavement
temperatures measured at two neighboring stations that bound it.
In practice, pavement temperatures will not normally be measured at each test
location. By clicking on the Interpolate Temperatures button in the main menu, you can fill
in the missing information by interpolation from the available pavement temperature
measurements. As a minimum, pavement temperatures should be measured at the beginning
