Salvaging Old High Type Flexible Pavements
High-type flexible pavements are those flexible pavements which cannot be readily sacrified to mix the surface and base material. They include bituminous concrete, sheet asphalt, penetration macadam and the heavier surfaces of the road mix type. It is important that repairs be made promptly to stop rapid spreading of disintegrating areas, to reduce the total amount of repair material required; and to save tires which may be seriously damaged by the sharp edges of potholes. Labor costs generally will be reduced by prompt repair work. Four methods of salvaging old high-type flexible pavements are presented: (1) patching, (2) temporary maintenance, repairs and resurfacing of pavements awaiting deferred construction, (3) substantial resurfacing where reconstruction is not anticipated, and (4) widening.
Accident Data Quality
This synthesis will be of interest to highway department administrators, accident records personnel, information systems and data processing management personnel, highway traffic and safety engineers, drivers' licensing officials, state and local police, as well as federal agencies, industries, traffic safety associations, and others responsible for the collection, analysis, and use of accident data. Information is provided on national accident data banks in addition to state and local practice associated with accident data collection, analysis, and evaluation. This synthesis describes current practice with respect to the characteristics and importance of accident data quality, including the reporting and data collection procedures, the analysis and quality control measures employed, and the communications systems used. This report of the Transportation Research Board discusses accident records systems, including data sources and users, considers the effects of inadequate data on analyses, and reviews data acquisition and processing programs that have had good results in the states using them. Recommendations for improving operating systems and for additional research are included.
Managing Highway Tort Liability
This synthesis will be of interest to highway agency administrative and executive officers, risk managers, legal officials, as well as to highway design, traffic, and safety engineers, enforcement agency personnel, claims managers, and others concerned with managing tort liability programs in state transportation agencies. It describes the state of the practice with respect to the manner in which these agencies manage highway tort liability programs. Management of claims associated with highways, streets, and pedestrian facilities is the focus of this synthesis, which describes program elements, costs, staffing, risk avoidance, and management requirements. This report of the Transportation Research Board describes the design and implementation of procedures and techniques to manage tort liability programs. Much of the material in this synthesis is also applicable to managing risks associated with modes other than highways within the state transportation agency. There is also applicability to local highway agencies, toll authorities, and public transit agencies.
