Thermoplastic Road Repair

Abstract

The roadways pothole is one of the major problem for municipal and highway engineers. This issue is even critical for roadways in locations with extreme weather conditions. In traditional practice of potholes repairs, they are filled with an asphaltic patching materials which are a quick fix but not effective because of short service lives, especially on heavily traveled roadways. This patching materials can readily migrate due to moisture, snow, ice, and normal rainfall and tends to degrade the roadways lifespan particularly in cold weather conditions where the patch is subjected to freeze-thaw cycles. To address this issue, researchers introduced the thermoplastic road repair approach. The hot-applied thermoplastic pavement compositions with polyamide resin content has many more benefits compared to the asphaltic patching materials, such as wear-resistance, low-temperature impact, and resistance to cracking from freeze-thaw conditions. The study presents various components of this thermoplastic road repair approach. It also reports serviceability, construction cost, benefits, and limitations of thermoplastic materials for roadways.
