• Abstract:
  The main objective of this study was to evaluate the performance and cost-effectiveness of the tow-behind combination ; infrared asphalt heater/reclaimer patching method and compare it to the throw and roll and spray injection methods. To ; achieve this objective a national survey was first conducted to document the experience of the infrared asphalt ; heater/reclaimer users in different states. In addition, a comprehensive testing program, that included installing over 60 ; patches using the three considered methods as well as monitoring the performance and survivability of those patches, was ; performed. The results of the survey and subsequent phone interviews indicated that the infrared asphalt heater/reclaimer ; equipment can significantly improve the performance and longevity of pothole patches and can be cost-effective when proper ; installation procedures are followed. The results of testing program indicated that the infrared method had much lower ; productivity than the other two methods. In addition, the throw and roll had better productivity than the spray injection method. ; The properties and storage procedure of the asphalt mixture used in the infrared method were found to affect the ; performance of the installed patches. Improper storage of the infrared heater/reclaimer equipment also was found to cause ; problems in igniting the infrared heater, which significantly increased the patching duration. In general, most of the ; deterioration in the patches installed using the different methods occurred in the first month of installation and continued after ; that but at much slower rate. The infrared patches had significantly better performance than those installed using the two ; other patching methods. The main distress in infrared patches was raveling, while it was dishing for the throw and roll and ; spray injection patches. The results of survivability analyses also indicated that the patches installed using infrared had much ; longer expected life than those installed using the other two considered methods. The results of the cost analyses showed ; that the infrared method can be more cost-effective than the spray injection method when used for winter pothole patching. ; For short term repairs, the throw and roll method was found to cost less than the infrared method if the user cost were not ; considered. However, for permanent repairs, the infrared method can be more cost effective than throw and roll method. In ; summary, the tow-behind infrared heater/reclaimer was found to be an efficient and cost effective method for patching certain ; types of potholes as well as performing other pavement repairs. A strategy for its deployment in Ohio is provided in this ; report.
