Abstract
Frost Penetration Mapping using Simulation with GIS
Track: Transportation and Logistics
Author(s): Stephen Farrington, Martin Gildea
A novel methodology was developed using numerical simulation, statistical regression, spatial interpolation, and GIS to predict maximum frost penetration depth in a typical pavement structure throughout the state of Vermont at different levels of statistical reliability. The methodology behind historic maps of frost penetration was unknown and did not appear to incorporate the influence of elevation, a key determinant in air temperatures affecting pavement surface cooling. New maps, developed in ArcView, will be used to design pavements for new road construction, which must extend to a specified percentage of the maximum frost penetration depth.
