| Description | Rubber-modified asphalt pavements have been used in Sweden and the United States since the 1970's. In these applications the ground recycled tire rubber particles (1/4 in. minus) are added to a gap-graded aggregate and then mixed with hot asphalt cement. The resultant paving mixture has been reported to have the following characteristics for cold regions: 1. Improved resistance to load-induced tensile cracking and to low temperature cracking. 2. Improved skid resistance under icy conditions. 3. Good resistance to studded tires and/or chains. 4. Reduced tire noise levels. Disadvantages include higher initial costs due to the rubber costs, the increased asphalt content required, and the unusual aggregate grading. However, these tend to be offset by the improved performance. |
