We develop an empirical tool to estimate optimal highway durability in cold regions. To test the model, we assemble a data set containing all highway construction and maintenance projects in Arizona and Washington State from 1990 to 2014. The data set includes information on location, time, type (resurfacing, construction, or lane widening), pavement material and thickness, and total expenditure for these projects. Using the data, we first estimate how highway maintenance costs and highway duration depend on pavement thickness and traffic loading. We then calibrate the effects of different deicers on highway durability and thus on highway maintenance costs. Finally, we demonstrate how the estimated and calibrated model can be used by planners to make optimal decisions for highway pavement and winter operations in cold regions.Date

Alaska's Inclusion in the Federal-Aid Highway Act of 1956, The Work of the Bureau of Public Roads and The Transition to StatehoodThis is the continuation of a research project which I undertook several years ago for DOT&PF. I delivered the final report in June, 1983, entitled Alaska Road Commission Historical Narrative. Subsequently, the Alaska Historical Commission provided an editing and a pre-publication grant. The University Press of America, Inc. of Lanham, Maryland accepted the revised manuscript for publication and it was published in November 1986 entitled Paving Alaska's Trails: The Work of the Alaska Road Commission. The present report continues the narrative from 1956 to 1959.

Highway Right-of-Way Sludge DisposalThis report encompasses a proposal to consider application of wastewater sludge to highway right-of-way. Conventional disposal of this sludge is a complex and expensive process and in some areas is severely restricted by land use and regulations. The report includes a literature review, a national survey of highway organizations and a hypothetical design analysis. Application of sludge to highway ROW can be beneficial by supplying nutrients required for plant growth, subsequent erosion stabilization and ultimate disposal of a waste resource. Disadvantages include negative public reaction, potential for contamination of ground and surface water, aesthetics, and relatively high costs. Preliminary findings of the report indicate the process is marginally feasible and recommends that a small pilot project should be conducted prior to full-scale consideration
