Synthesis of Information Related to Highway Problems. Topic 41-04. Sustainable Pavement Maintenance Practices

Increasing societal awareness of the environmental effects of the surface transportation system has led to new demands on transportation agencies to provide environmentally responsive infrastructure. Pavement maintenance and preservation practices are applied to restore pavement condition and delay deterioration. They may also extend the service life of pavements and influence the sustainability of transportation infrastructure. Although these practices consume large amounts of energy and raw materials on a national scale, they can also help delay the need for far more costly and resource intensive rehabilitation. There is a need to document maintenance and preservation practices and treatments, and their effect on pavement and environmental performance. Domestic and foreign highway agencies have implemented sustainable products and practices, and have developed training to transfer these technologies to their work force. Therefore, it is important to synthesize the state of practice in a single document where public highway agencies can find proven methods of effective pavement maintenance that improve environmental performance. This synthesis will gather and summarize information on the following topics: (1) Current pavement maintenance programs described by respondents as sustainable or green, and whether such programs are part of agency-wide sustainability programs; (2) Use of recycled and alternative materials in pavement maintenance; * How sustainable maintenance practices are defined and measured; * (3) Factors and data (such as cost, environmental performance, workforce suitability) used in determining practices for sustainable maintenance and preservation; (4) Methods for data collection, storage, and analysis; * Public and private sustainable maintenance specifications and guidelines; *and (5) All ongoing research; and * Information gaps and the need for future research. The scope includes all types of pavement, including gravel and other low-volume roads. The report will survey all state DOTs (directed to the AASHTO Highway Subcommittee on Maintenance member) and Canadian provincial ministries of transportation. Additional information may be collected from selected local agencies, contractors, suppliers, and consultants. This information will identify pavement maintenance practices and their associated pavement and environmental performance. International information will be gathered from a literature review. Three to four agency programs with effective practices and approaches will be selected and case studies of their practices will be described.
