Initial Performance of Asphalt Overlays on Overlaid Jointed Concrete Pavement (JCP) and on Flexible Pavements in Field Test Sections in Lufkin, Texas
This report focuses on the performance of the various rehabilitation strategies implemented in the test sections placed on US 59 by the Lufkin District. Specific chapters discuss traffic, temperture, deflections, rutting, profiles, and the effectiveness of each rehabilitation strategy. The two sets of test sections constructed for this study have served as representative sections of rigid and flexible pavements in the Lufkin District. We surveyed, measured, and recorded at set intervals the rutting, profiles, and various kinds of cracks. Deflection measurements were recorded during the three stages of construction: before miling of the existing overlay, after miling, and after construction of the new overlay. These data summarize the structural response of the different pavement systems. Backcalculating the stiffness for the different layers of each test section shows the stiffness variation under repeated traffic loads. The rut depth survey verified that a pavement that has had rutting problems in the original pavement continues to have rutting problems. It also showed that the flexible base layer does not prevent rutting, even though it can prevent some reflective cracking.
