• Abstract:
  The South Dakota Department of Transportation developed project SD93-03 primarily to study the effectiveness of various techniques for determining appropriate spring restriction periods. A literature review, interviews with State agencies, interviews with users, and a series of field tests were performed during this project. The results show that temperature data are an effective means to identify significant thawing periods, which signal the need to begin load restrictions. A method for measuring the degree of freezing to which a pavement is subjected, using minimum and maximum air temperatures, was developed. The effectiveness of using speed restrictions instead of load restrictions was also studied, but no information on the benefits of speed restrictions was found. In fact, it was found that the use of speed restrictions can actually have a detrimental effect on pavements.
