Evaluating Performance of Asphalt Pavement Based on Data Collect during IRP
| 项目名称： | Evaluating Performance of Asphalt Pavement Based on Data Collect during IRP |
| 摘要： | In 1999, the Arkansas State Highway and Transportation Department began an ambitious program to rehabilitate over 300 miles of Interstate in 5 years. As part of this rehabilitation program, approximately 270 miles of deteriorated concrete pavement was rubblized and overlayed. Many of these pavements constructed during this program are exhibiting a severe level of cracking. Most of these severely cracked asphalt pavements are located west of Conway on Interstate 40; while the rubblized pavements east of Little Rock on I-40 and I-30, which were constructed at virtually the same time, exhibit much less cracking. There have been several theories regarding the wide range of performance of these pavements. The most common theories include poor construction techniques, poor bonding to previous lifts, overheating of the asphalt, and poor binder quality. An evaluation of material properties, construction techniques, and other factors is needed to determine why some projects performed much better than others. |
