Project Description Heading link
Pavement design has always been a vital component in the transportation industry, and it is estimated that of the 2.6 million miles of paved roads in the U.S., over 94 percent are surfaced with asphalt. These paved roads, like vehicles, need to be maintained and inspected in order to ensure the safety of the motorists, bicyclists, and pedestrians alike. An 18-month study conducted by The Pacific Institute for Research and Evaluation examined information from the National Highway Traffic Safety Administration, Federal Motor Carrier Safety Administration, and other government agencies and concluded that roadway deficiencies, such as potholes and black ice, cause more than 42,000 deaths per year. With these accidents caused by poorly designed or maintained roads, an innovative and efficient pavement design is required to mitigate the risks of everyday use. The team will be analyzing an existing asphalt roadway that lacks structural sufficiency and will redesign the existing typical section to include an adequate, sustainable asphalt typical section. These improvements consist of pavement patching, hot-mix asphalt surface removal, resurfacing with binder and surface course, and sidewalk ramp improvements for ADA compliance. Through the implementation of these improvements, the driving conditions will drastically improve for motorists and meet IDOT’s ADA requirements for sidewalk compliance. Milling and resurfacing the roadway will reduce the overall pavement life cycle cost by eliminating the need to reconstruct the road and extending the life cycle of the roadway for decades to come. Following the “IDOT Standard Specifications for Road and Bridge Construction Manual” and analyzing and comparing previous pavement designs that failed and were successful, an adequate resurfaced road will be designed and constructed under this analysis.
