TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 338: Thin and Ultra-Thin Whitetopping summarizes available information to document how state departments of transportation and others are currently using thin and ultra-thin whitetopping overlays among various pavement rehabilitation alternatives. The report covers all stages of the proper application of whitetopping overlays, including project selection, design, materials selection, construction, maintenance, and eventual rehabilitation or replacement.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 689: Costs of Alternative Revenue-Generation Systems presents a framework for analysis of the direct costs incurred in generating the revenues that support federal-aid and state highway construction, operations, and maintenance and uses that framework to estimate unit costs for fuel taxes, tolling, vehicle-miles of travel fees, and cordon pricing schemes."--pub. desc.

A transportation expert makes a provocative case for changing the nation’s approach to highways, offering “bold, innovative thinking on infrastructure” (Rick Geddes, Cornell University). Americans spend hours every day sitting in traffic. And the roads they idle on are often rough and potholed, with exits, tunnels, guardrails, and bridges in terrible disrepair. According to transportation expert Robert Poole, this congestion and deterioration are outcomes of the way America manages its highways. Our twentieth-century model overly politicizes highway investment decisions, short-changing maintenance and often investing in projects whose costs exceed their benefits. In Rethinking America’s Highways, Poole examines how our current model of state-owned highways came about and why it is failing to satisfy its customers. He argues for a new model that treats highways themselves as public utilities—like electricity, telephones, and water supply. If highways were provided commercially, Poole argues, people would pay for highways based on how much they used, and the companies would issue revenue bonds to invest in facilities people were willing to pay for. Arguing for highway investments to be motivated by economic rather than political factors, this book makes a carefully-reasoned and well-documented case for a new approach to highways.
