Abstract

Temperature is an important parameter to consider for asphalt paving since this work is generally susceptible to weather due to outdoor construction. The South Dakota Department of Transportation (SDDOT) developed working day weather charts in 1998 to address the expected adverse weather days. This thesis investigated the effect of temperature on adverse weather days for asphalt paving and compared them to the value reported in the 1998 SDDOT study. Moreover, the thesis also examined how closely the maximum temperature data from project sites' weekly progress reports (WPR) matched the data from the closest weather stations. When the maximum temperature (TMAX) of a day is below a certain threshold maximum temperature, that day is counted as a threshold violation (TV) day. The weather data was collected from the National Oceanic and Atmospheric Administration (NOAA) website, and the WPR data of project sites was obtained from SDDOT. Average and 7-year moving average are used to analyze the TV days. The results show that the threshold violation days are generally greater than the State average adverse weather days at 45°F threshold both annually and monthly (January, April, October). However, these violation days are generally less than the State average when the threshold is 40°F. The lift thickness of surface course must be greater than 1 inch, when the temperature during asphalt paving is between 40°F and 45°F in order to get more working days. Most of the project sites (6 out of 9) show a low percentage of maximum temperature data match with the corresponding NOAA stations. It is apparent from the analysis that that there is no direct relationship between the data match percentage, and the distance of project site and NOAA station.
