Design and Construction of Pavements in Cold Regions: Questionnaire Survey of State Departments of Transportation

A questionnaire survey was conducted of 23 state departments of transportation (DOTs) to investigate the state of the practice concerning certain aspects of design and construction of pavements in cold regions within the United States. In particular, the methods and standards employed for characterizing materials, improving soils and aggregates, and determining pavement layer thicknesses were explored. The survey included 15 questions specifically addressing material specifications, identification of frost-susceptible soils, stabilization techniques, geosynthetics, and spring load restrictions and winter premiums. The information obtained in this research represents a unique compilation of standards of practice that have been developed by DOTs based on years of experience and research in their respective jurisdictions. While this research allows engineers at state DOTs to compare their pavement design and construction practices with those of other states represented in the survey, consulting engineers and engineers in local governments involved in the design and construction of pavements in cold regions can also benefit from this work.
