Pavement Repair Strategies for Selected Distresses in FM Roadways
Expansive soil is considered one of the most common causes of pavement distresses in FM roadways. Depending upon the moisture level, expansive soils will experience changes in volume due to moisture fluctuations from seasonal variations. The objective of this research was to evaluate existing repair projects on selected FM roadways. Those roadways experienced failures in the form of fatigue and rutting in the wheel path, and longitudinal (faulted) cracking including edge cracking. The causes of those failures were mainly linked to high PI expansive soil and narrow pavement. This study involved field and laboratory testing on those projects to examine the effectiveness of the applied treatments. The projects presented in this report are examples of how TxDOT districts choose to address severe pavement conditions that lead to failure on FM roads. Some of those examples are innovative, and others are routine. These projects do not represent the only options for treatment, and each project should be designed based on its existing conditions, such as the intended design life cycle, cost effectiveness, local climate, local traffic, and available local materials.
