• Abstract:
  Seasonal variations in the strength of flexible pavements are known to influence their service life, especially in the northern United States and Canada. Less is known regarding seasonal effects in a milder climate such as that of Texas. This study was undertaken in an attempt to determine where and when, in Texas, such variations exist, what their magnitudes are, and how they should be accounted for in the pavement design process. Using deflections produced by a standard loading system (the Dynaflect) as an index to strength, periodic measurements were made over one year's time at 180 test points on flexible pavements located in five widely separated areas of the state.
