TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2228 consists of 15 papers that explore performance bond benefit–cost analysis; green contracting in highway construction; optimal hedging of commodity price risks in highway contracts; wireless real-time productivity measurement system; a performance attributes matrix for highway rehabilitation projects; adopting the project delivery method with early contractor involvement; and design of steel bridges for Shinkansen, Japan, high-speed rail.
This issue of the TRR also examines key performance indicators in highway design and construction; determining optimum acceptance sample size; severity of non-normality in pavement quality assurance; performance-related specification for superpave pavements; variability and normality assumptions for Virginia Department of Transportation volumetric properties; Wisconsin method for probing Portland cement concrete pavement for thickness; cooling curves prediction model for non-conventional asphalt concrete mixtures; and density, permeability, infiltration, and absorption used to assess quality of hot-mix asphalt longitudinal joints.
