The objective of this study was to develop a method to predict the timing of weight limits on secondary highways in Wisconsin. Two types of weight limits are of interest: overloads when the pavement is frozen and weight restrictions during thawing and post-thawing recovery period. To meet this objective, three sections of secondary highways with flexible pavements were instrumented and monitored to determine how freezing, thawing, and post-thaw recovery affect pavement stiffness. Data collected from these sites were used to develop a computer model (UWFrost) that can be used to predict seasonal changes in the support capacity of pavements.

Winter pavement overload permits and spring load restrictions areimportant to maximize pavement life. In cold regions freeze and thaw conditions have a great effect on the bearing capacity of asphalt concrete (AC) pavement and its sublayers. Studying AC surface deflections from falling weight deflectometer (FWD) tests assists in determining the condition of the surface, base, and subgrade layers of a pavement system. FWD test results are taken from the LTPP Information Management System (IMS). FWD data deflectionbasin indices can be calculated to analyze AC pavement at different seasonalconditions. This data will aid in determining times when load permits and restrictions should be applied. Seasonal effects on AC pavements significantly affect the strength of theAC sublayers. In freezing temperatures the AC pavement and its sublayers become much stronger, where overload permits can be granted. However, when the system thaws the layers become extremely weak. Pavement is subject to damage and FWD tests show significant increases in surface deflection. When this happens spring load restrictions should be utilized to preserve the pavement. An in depth study of FWD data can be used to recommend the best times to enforce winter overload permits and spring load restrictions. Using the BISAR computer program, AC pavement can be modeled to represent FWD behavior at various times.
