| 摘要： | The objectives of this project were to identify and analyze the nighttime paving traffic control standards in other states and compare the effects of daytime vs. nighttime paving on quality, safety, costs, and construction time. Surveys of various Department of Transportation (DOTs) and local contractors were conducted. The safety issues involved with nighttime paving in South Carolina, including workers and the travelling public and "reasonable detour" concept used by other states to determine the advantages and disadvantages of the process were investigated. In addition, the cost and the quality measurements of nighttime paving vs daytime paving (e.g., core compaction data, ride quality, overall pay factors, etc.) were studied and analyzed. The construction time of nighttime paving vs. daytime paving were measured. The data were gathered from various DOT districts around the state. The findings, in general, indicated that many states pay for mixtures used during night time paving. In addition, the survey responders indicated that many states do not keep track of many aspects and important information regarding this issue. The data from all districts of South Carolina indicated that, in general, the cost of mixtures used (per ton of mix) in night time paving is higher than day time paving operations. In addition, more accidents happen during night time paving vs day time paving. |
