An Analysis Of The Effect Of Temperature On Asphalt Paving In South Dakota, S M Rahat Rashedi
An Analysis Of The Effect Of Temperature On Asphalt Paving In South Dakota, S M Rahat Rashedi
Electronic Theses and Dissertations
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) …
Application Of Drainage Water Management And Saturated Buffers For Conservation Drainage In South Dakota, Abhinav Sharma
Application Of Drainage Water Management And Saturated Buffers For Conservation Drainage In South Dakota, Abhinav Sharma
Electronic Theses and Dissertations
Edge of field practices such as drainage water management (DWM) and saturated buffers can reduce nutrient transport from croplands to surface waterbodies. DWM uses stackable weir boards in a control structure to manipulate the water table depth throughout the cropping season and reduce the amount of nutrient rich water draining out from the field. Saturated buffers, on the other hand, use a control structure to divert water draining out from the cropland to a vegetative strip via a subsurface tile installed parallel to a waterway. For the saturated buffer systems, a combination of natural denitrification, nitrogen mineralization, and plant uptake …
Foundation Design Of Low Volume Roads: Evaluation And Performance, Alyssa Clemen
Foundation Design Of Low Volume Roads: Evaluation And Performance, Alyssa Clemen
Electronic Theses and Dissertations
A majority of roads in the state of SD are low volume roads (LVRs). The SDDOT has developed simplified methods for LVR pavement thickness selection. These guides allow users to obtain recommended asphalt surfacing and base course layer thickness based on the subgrade support and the average daily traffic (ADT) of the road. The main objective of this study is to relate the surface condition of LVRs to their ADT, layer thicknesses, foundation material properties, and maintenance. A secondary objective was to evaluate if the Dynamic Cone Penetrometer (DCP) is an acceptable tool in determining the subgrade support by using …
