The University of Alaska
Fairbanks: Preventing frost
boils in the Dalton Highway
Beaver Slide area, Alaska (2012)
Every year, the Beaver Slide area of the
Dalton Highway suffered severe road
damage through (1) frost heave and subsequent thaw weakening and (2) upward
pressurized water flow to the road surface
during lengthy rain events. (Figure 5)
In 2012 this instrumented test section was monitored for temperature and
moisture content through the placement
of sensors in 22 locations within the road
cross section.
The moisture content values on the
right side of the section measured on
September 4 are significantly lower than
the readings taken on August 19. The
