Design of Roads and Railways in Cold Climate
Public transportation and municipal infrastructure in the far North are facing important challenges to its operation and sustainability. Both in Canada and Norway there is an increasing need for multidisciplinary and highly skilled practitioners in science and engineering related to cold regions in order to develop sustainable infrastructure in a context of climate change. Construction techniques developed in the southern parts of North America and in Europe cannot simply be applied to transportation infrastructures in our cold climate environments. Knowledge of the key science foundation for frost action is required to adequately address the needs of industry and academic research. Climate change adds considerable uncertainty to design problems, but by sharing our expertise between different science and engineering research environments, and with industry, we will improve our capacity to respond to future cold region issues.
This course is an international and multidisciplinary intensive course aiming to disseminate the knowledge on road and railway construction in cold climate regions with a special focus on the conditions in Norway and Canada. This course is part of the FROZEN CANOES project that aims to contribute to high quality research-based education by combining geoscience and engineering knowledge from Norway and Canada. FROZEN CANOES is funded by the INTPART program of the Norwegian Research Council and the Centre for Internationalization of University Studies in Norway.
The course is primarily intended for graduate students at the master level in Engineering and Earth Sciences as well as for PhDs and professionals.
The full course gives 7.5 ETC credits, which is equivalent to 6 Canadian credits.

- Basic pavement design (strength, stress and structural design)

- Identify deterioration mechanisms and choose appropriate materials
- Perform thermal modeling
- Collaborate in an interdisciplinary team of geoscientists and engineers
- Respond with innovative solutions to cold regions transportation issues
- Carry out field and lab work related to frost action
- Designing a road/railway in cold climate using TEMP/W
- Good judgment on the best method of mitigation to use
Mandatory preparation prior to the course – online modules
Two online learning modules are mandatory as course preparation and need to be achieved during the month of September to allow more time on practical field aspects of frozen ground science and engineering during the intensive course. These online modules will focus on heat transfer and freezing-thawing soil mechanics.
MODULE 1: HEAT TRANSFER (2-13 SEPTEMBER 2019, 9 hours of lecture and 9 hours of personal work)
The module introduce the students to the basics of heat transfer in freezing soils. Conduction, convection and radiation heat transfer mechanisms as well as phase change and enthalpy are covered. Thermo-physical properties of soils and construction materials are presented including various prediction models available from the literature. Effects of insulation layers in road structures are also discussed in terms of frost protection and risk of differential surface icing.
MODULE 2: FREEZING-THAWING SOIL MECHANICS (16-27 SEPTEMBER 2019, 9 hours of lecture and 9 hours of personal work)
This module introduce the students to the mechanics of freezing, frozen and thawing soils. It includes basic information on freezing soils: the mechanics of frost heave and the strength, stiffness and deformation characteristics of frozen soils. The module discuss the movement of water in freezing and frozen soils, with attention given to the unfrozen water content in fine-grained soils (silts and clays) at temperatures below 0 °C and the resulting hydraulic conductivity of these materials. This module also presents the thaw consolidation theory and the settlement behavior of ice-rich soils as frozen ground thaws.
