Pavement maintenance is broadly classified into two categories: proactive and reactive. Proactive, or planned, maintenance describes actions that are programmed to occur at a convenient time in terms of climatic conditions, traffic, availability of personnel and equipment, and so on. It may be accomplished either by contract or with in-house staff. The need for reactive maintenance, on the other hand, can occur at any time. Maintenance needs that arise during winter and must be completed to maintain the safety and serviceability of roadways may be particularly problematic. Safe operations during adverse conditions and repair material performance in winter weather are two considerations that make winter maintenance challenging. Cold weather maintenance consists of critical actions which must be done immediately to maintain the safety and serviceability of roadways. These actions include patching potholes and punch outs, removal of snow and ice, and deicing.
The objective of this synthesis is to document current state departments of transportation (DOTs) practices for performing reactive winter roadway maintenance.
Information to be gathered includes (but is not limited to):
• Roadway maintenance activities performed during the winter;
• How reactive wintertime roadway maintenance may differ from when these activities are done at the optimal time;
• Whether winter maintenance treatments are considered temporary, with plans to conduct repairs in better weather, or whether they considered as permanent repairs;
• Special considerations for the impact of snow and ice removal on winter maintenance performance;
• Material selection, timing, procedures, and required equipment specific to winter maintenance operations; and
• Whether information about wintertime pavement maintenance operations is integrated into a DOT asset management system.
Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected DOTs for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
