This report contains guidelines and recommendations for managing and designing for friction on highway pavements. The contents of this report will be of interest to highway materials, construction, pavement management, safety, design, and research engineers, as well as others concerned with the friction and related surface characteristics of highway pavements.
This report contains a list of 39 factors that influence the linkage between programming and long-range plans. This list was developed from recent literature and extensive interviews with agency staff and other experts in the field. While the discussion of the critical factors is helpful, the report takes this topic one step further by providing suggested paths for improving the linkage between planning and programming.
Explores practical selection criteria for bridge-pier scour countermeasures; guidelines and specifications for the design and construction of those countermeasures; and guidelines for their inspection, maintenance, and performance evaluation. Produced along with the report is an interactive version of the countermeasure selection methodology, which defines the proper conditions for the use of each specific countermeasure, and a reference document that contains detailed laboratory testing results and translations of three German "Code of Practice" documents.
