Book Description
Propagation of cracks from existing pavements into a new asphalt concrete overlay (reflective cracking) is a major problem for both rigid and flexible pavements. Reflective cracking in pavements compromises ride quality and reduces the service life of the pavement. Reflective cracking of the asphalt layer over jointed concrete pavement is a perennial problem in Virginia and elsewhere. State transportation agencies continue to try various available treatment methods to delay or prevent reflective cracking with corrective or restorative maintenance. Some of those treatments include using paving fabric as an interlayer. Virginia has anecdotal experience with paving fabric interlayers, but little well-documented history with which to assess performance. The objective of this study was to establish a performance baseline for fabric interlayers in conjunction with asphalt concrete overlays on existing flexible, rigid, and composite pavements by documenting the installation and initial field performance of several projects in Virginia. Two types of interlayer fabric were used. One of the interlayers needed an asphalt leveling course for placement based on the manufacturer's specifications. As expected, all of the sections with interlayers are performing well. However, most of the sections were placed in 2017 and 2018, and hence the performance data are preliminary. These sections need to be monitored continuously to track pavement distress and performance over time. The cost of using interlayers in pavement ranged from 6 .0 dollars to 8 .0 dollars per square yard, depending on the type of fabric and installation method. Long-term performance data are needed to assess the benefit-cost effectiveness of using paving fabric interlayers in pavements.

Book Description
Asphalt-rubber and engineering fabric interlayers have been used to retard reflective cracks in asphalt concrete overlays. These materials have generally performed satisfactorily in warm climates; however, performance in cold climates has been less than desirable. The asphalt-rubber and engineering fabric rehabilitation techniques have been used to retard the reflection of cracks in existing asphalt concrete and portland cement concrete pavements through asphalt concrete overlays. These rehabilitation techniques also decrease the size of cracks that reflect through, thus retarding the amount of water penetrating into the base course and underlying subgrade. Guidance is provided for using asphalt rubber and engineering fabrics to maximize performance in reducing reflective cracking. This study should result in improved performance of overlays and, subsequently, substantial monetary savings to the taxpayers.
