The paper describes an investigating into the application of a polymer concrete using a recyclable material such as polypropylene and chopped tire rubber as aggregate material to provide a durable and cost-effective alternative to the existing cold mix asphalt (CMA) pothole repair material. Three different aggregate mix designs, including traditional crusher- sand and -stone, rubber crumbs, and plastic chips, in combination with Vinyl Ester, Polyester, Polyurethane and Furan resin were combined to create 12 possible polymer concrete mixes to be used as a rapid pothole repair material. These polymer concrete mix designs were tested for common properties and characteristics typically experienced on road surfaces. These include characteristics such as compressive strength, flexural strength, and abrasion resistance. All results obtained from the various tests performed indicated that the polymer concrete mix designs exhibit enhanced physical properties compared with CMA and would thereby increase the durability and lifespan of repaired potholes when using this material.

摘要

The paper describes an investigating into the application of a polymer concrete using a recyclable material such as polypropylene and chopped tire rubber as aggregate material to provide a durable and cost-effective alternative to the existing cold mix asphalt (CMA) pothole repair material. Three different aggregate mix designs, including traditional crusher- sand and -stone, rubber crumbs, and plastic chips, in combination with Vinyl Ester, Polyester, Polyurethane and Furan resin were combined to create 12 possible polymer concrete mixes to be used as a rapid pothole repair material. These polymer concrete mix designs were tested for common properties and characteristics typically experienced on road surfaces. These include characteristics such as compressive strength, flexural strength, and abrasion resistance. All results obtained from the various tests performed indicated that the polymer concrete mix designs exhibit enhanced physical properties compared with CMA and would thereby increase the durability and lifespan of repaired potholes when using this material.
