| 摘要： | Improved methods for evaluating the quality and uniformity of hot-mix asphalt (HMA) overlays have become available over the past few years. Non-nuclear density gauges introduced to market provide rapid alternatives to nuclear gauges for field measurements of pavement density. Additionally, developed infrared imaging and ground-penetrating radar (GPR) technologies can provide rapid assessment of a project for segregation, uniformity, and overall quality, as illustrated through previous Texas Department of Transportation (TxDOT) Project 0-4126. This current project 0-4577 focused on evaluation of available non-nuclear density gauges and further refinement of infrared imaging and GPR for use in evaluating HMA overlays. |
