Influence Of Traffic Loading On Transverse Cracking On Asphalt Concrete Pavement Under Wet-Freeze Areas

Transverse cracking is pavement distress typically associated with low temperature. However, in a recent technical report from the Federal Highway Administration Publications: "Impact of Environmental Factors on Pavement Performance in the Absence of Heavy Loads" by Leslie Titus-Glover, Michael I. Darter, and Harold Von Quintus, one of the findings is that there is more transverse cracking on sections with higher truck-traffic. This poster focuses on investigating the effects of traffic loading on transverse cracking on asphalt concrete pavement under wet-freeze areas using LTPP data only. One climatic area was used to assure minimal variation of climate exposure, and sections from SPS-1, GPS-1 and SPS-8 were also utilized. This paper illustrates the relationship between traffic loading and transverse cracking through regression analysis.
