FINAL REPORT FOR POTHOLE RESEARCH
The major objectives of this study are: to compare the performance of pothole repairs made with heated and unheated stockpiled WS patching mixture, to determine the optimum amount or degree of hole preparation, to compare compaction methods and equipment, and to determine the combination of factors which will result in the most satisfactory pothole repair. Conclusions from the study include the following: the greatest number of successful pothole repairs were made using stockpiled WS patching mix which was heated before use to 200 deg F in a Porta-Patcher; pothole repairs made with unheated WS patching mix settled even though they were placed at 90 deg outside temperature, in good weather conditions, and compacted to the highest density that could be achieved with good compactors; well-compacted, heated WS mix patches without tack and seal exhibit no shoving and appear to be more stable than similar repairs made with tack and seal; all three types of mechanical compactors tested during the study were able to attain the required density with the only difference between them being the number of passes necessary to obtain the required density; manual compaction can be effective on very small potholes filled with heated mix; hole preparation did not appear to be a significant factor to the performance of the patch; and once the mix in the patch has begun to shove, the addition of new mix material to restore its level with the existing pavement did not correct the shoving problem.
