Abstract: A forensic study was conducted to identify the cause of the premature cracking on three recently completed projects that were built with the same design. Nondestructive [ground penetration radar, falling weight deflectometer ...

Abstract: An investigation was conducted to determine the root cause of the premature pavement failure. The premature pavement failure occurred in the form of rutting and alligator cracking. Although the affected portion was repaired ...

Abstract: A premature pavement overlay failure had occurred only 1 day after it was opened to traffic. Crescent-shaped cracks were intermittently spread over a section about 3 mi in length. Dynamic cone penetrometer results demonstrated ...

Abstract: Since reflective cracking is related to both the existing pavement condition and the overlay material, appropriate tools are needed to characterize both properties. The rolling dynamic deflectometer (RDD) was employed to ...

Abstract: The nondestructive mapping of anomalies and voids under roadway pavements is critical to highway authorities because of the potential loss of support that would lead to safety hazards. 400 MHz ground-coupled penetrating ...

Abstract: Diamond grinding (DG) has been used by various districts to improve skid resistance (reduce accidents and fatalities) and improve ride quality [reduce international roughness index (IRI)], with the added benefit of reducing ...

Abstract: This paper presents three field projects to illustrate the integrated approach to forensic investigations of roadway pavement failures used widely in Texas. In each case, the combined ground-penetrating radar (GPR) and ...

Abstract: This paper presents the results of several investigations to identify the underlying causes of longitudinal cracking problems in Portland cement concrete (PCC) pavement. Longitudinal cracking is not intended and detrimental ...

Abstract: The main objective of the most recent Mobile Load Simulator (MLS) test program was to conduct a comparative study of two rehabilitation processes, Rehabs A and B, constructed on the south- and northbound lanes of US281 ...
