The effectiveness of a reinforcing mesh system for localized asphalt pavement repair
A testing program was carried out to study the effectiveness of a reinforcing mesh system in improving performance and reducing load-induced asphalt pavement deflections in localized repairs. To simulate the field condition, a concrete pipe with an 2.6-m inside diameter and a 1.8-m height was used as a soil box, within which a typical asphalt pavement section (150 mm binder and 50 mm surface) was placed over 1.2 m of soil. A 0.9 x 1.2-m opening was then cut and asphalt and soil were removed and replaced to imitate the repair process (eg utility cut). A total of eight different repair sections were studied. The parameters studied included the use of the reinforcing mesh system, varying backfill soil density, and cut geometry (straight vs T-section). It was observed that the use of the reinforcing mesh system reduced the deflections in some cases. However, it cannot be used as a substitute for good asphalt and soil compaction.
