This technical report synthesizes information on techniques to reduce the impact of road construction, rehabilitation and maintenance activities on road users (driving public and construction workers) and the adjacent land use (homeowners, businesses, etc.). The study included a survey to collect agency information and to summarize and draw conclusions on the impact of road construction and maintenance activities on road users (driving public and construction workers) and the surrounding land use. Information collected as a part of the study included solutions to improve user or construction worker safety, regulations (e.g. requirements for construction work to take place during weekends or nights), environmental considerations (e.g. dust control), quality/performance (contractor incentives to complete a project earlier to reduce the impact on road users) or special treatments to ensure that local traffic is not adversely impacted by construction activities, etc. In addition to the synthesis of information, this document outlines the process of innovation and provides case studies of innovative techniques to minimize the impact of road work on the surrounding environment. There are several ways for introducing innovation in the design and construction of roads among which: regulations, procurement methods and policy of road managers. Each of them has financial implications which will be faced either by the road manager who will pay for the reduction of impacts, or by the contractor of innovation allows for higher productivity or other savings. The appendices of this report present some innovations which can be used to reduce the impact of road construction and maintenance activities on road users and adjacent land use. (Author/publisher)
