ENERGY BALANCE ON A PAVED SURFACE
Energy balance data from Portland cement concrete test slabs at the Lebanon Regional Airport, Lebanon, New Hampshire, are compared with calculated quantities. Energy balance components are calculated from techniques used by Scott in developing the cumulative heat flow technique for determining frost and thaw depths. Techniques for computing frost and thaw depths are briefly reviewed to illustrate applications of the surface energy balance in frost and thaw depth calculations. Comparison of calculated and measured components of the energy balance indicates that computational techniques and/or data measurement techniques must be improved to provide estimated frost and thaw depths that are within 15 percent of measured depths. /AUTHOR/
