Cold Weather Construction Applications: A Case Study on Cold Weather Construction Practices on the I-15 CORE Project
The Utah Department of Transportation completed the Utah County Interstate 15 (I-15) Corridor Expansion (CORE) project in an unprecedented 35 months, making I-15 CORE the fastest billion-dollar public highway project ever built in the United States. In an area like Utah, where a cold dry climate prevails, construction activities tend to taper off during the winter. On the I-15 CORE project, however, cold weather construction practices were incorporated throughout all levels of the project to accommodate year-round construction. The 35-month project flew through two winters that routinely saw temperatures drop below 0°F. Construction of portland cement concrete pavement, hot mix asphalt, mechanically stabilized earth walls, and bridge structures continued even during these cold periods. In order for continuous construction to proceed during these colder periods, the planning and staging of summer activities was scheduled to set up a queue of winter activities that were inherently less sensitive to the low temperatures and weather conditions. In addition, construction materials less sensitive to temperature drops were designed or selected for use during the winter months. With the aid of innovative techniques and materials including maturity meters, non-frost susceptible materials, tenting, ground heaters, blankets, and hot water, the project moved on, even allowing for a 2011 Christmas Eve pavement placement. Although cold weather construction activities tend to cost more, the I-CORE project was completed six months ahead of schedule and $260 million under budget. The objective of this paper is to present a review of the cold weather construction practices, techniques, and lessons learned on the I-15 CORE project in the form of two project-specific case studies.
