Prediction of remaining life on airport pavements
The University of Texas at Austin evaluated the remaining life of Runway 17R/35L using new technologies. Previous evaluations of remaining life using the declining pavement condition index (PCI) were determined to be inadequate for busy commercial service airports on jointed concrete pavements. A Rolling Dynamic Deflectometer (RDD) was developed to provide a continuous deflection profile for the runway and taxiway. Cross-hole seismic testing, indirect tensile and fatigue testing of cores were used with a new measure of fatigue cracking to predict remaining life. Remaining life of the runway was predicted for five different failure modes: surface distress, loss of subgrade support, surface roughness, concrete fatigue, and deterioration of joints.
