| 摘要： | The use of foamed asphalt for stabilizing the base of roadway pavements is not a new concept. The method has been used successfully in many projects. Two projects of this kind were selected for performance evaluation under a PENNDOT sponsored research program. The two municipal, low-traffic roads are located in Pennsylvania in Cecil and Peters Townships. The deteriorated roads needed rehabilitation. Therefore, they were milled, pulverized, and stabilized with foamed asphalt bases during July and August 2001. The stabilized road provided a strong base for the hot mix asphalt overlay that was placed during September 2001. During this period, construction was monitored by the research team. The roads were inspected at different time intervals for signs of distress. Loose samples from the stabilized base material were procured at the time of construction and were characterized in the laboratory. The results of evaluation so far indicate that the roads have been performing very well. No signs of distress have been observed on either of the roads. This research project as well as several other projects has indicated that base stabilization with foamed asphalt can be a very effective and economical approach for rehabilitation of deteriorated pavements. |
