No full textSPR-2642Until the early 1990s, curling and warping of Portland cement concrete pavement did not concernpavement engineers in many transportation agencies. Since beginning construction of the interstate system in theUnited States in the late 1950s through the late 1980s, the performance of Portland cement concrete pavement hasbeen associated with properties of concrete as a pavement material. In those years developed standards anddesign guidelines emphasized better concrete materials and construction control. At the time, combining curlingand loading stresses was quite controversial due to the nature of the load-carrying capacity of concrete pavementand the occurrence of types of loads. Arguments developed that the types of loads (traffic and curling) rarelyoccurred at the same time of day. The concrete pavement design principle did not include the effects of curlingand warping of concrete pavement as determining design factors in pavement performance.This research project was initiated as a response from the INDOT Pavement Steering Committee relatedto the joint spacing of Jointed Plain Concrete Pavement in Indiana. There was an initiative in the Committee toreduce the joint spacing from 18 feet to 15 feet as a way to reduce premature concrete pavement deterioration.There was an indication that some newly paved JPCP had transverse cracks even before the pavement sectionwas opened to traffic.In this experimental study, several important conclusions were drawn from temperature analysis, stressstrainanalysis, and other data analysis. The analysis from this experimental study supports the decision byINDOT to shorten the concrete pavement joint spacing to increase the performance of Jointed Plain ConcretePavement in Indiana

No full textSPR-3115In 2005 the Indiana Department of Transportation (INDOT) went through a complete reorganization of its operations going from centralized to decentralized (District) management. This reorganization gave Districts autonomy to manage construction projects with one exception all added capacity projects are managed in the central office by the office of project management. Following in 2006 INDOT initiated a program named "Major Moves." This is a ten year major road building program that was funded partially through a 4 billion dollar lease of the Indiana Toll Road. Through Major Moves annual new construction will go from 213 dollar million in FY 2006 to 1.2 dollar billion in FY2009. These two factors caused INDOT to change their approach toward managing design and construction. This "new" approach toward projects requires an individual to manage projects with skills and functions that are not common at INDOT. Therefore the purpose of the project was to: -Determine what skills were needed for INDOT project managers -Develop a training program to develop these needs -Deliver a training program This report describes the training program established at INDOT and contains the resources available for project managers and training materials

No full textSPR-3409Traffic signal systems represent a substantial component of the highway transportation network in the United States. Unfortunately, most agencies struggle to meet the challenge of finding enough resources to properly update signal policies and timing plans to accommodate changing traffic demands. The traffic engineering community has been aware of system underperformance for several years, but most proposed solutions have been too expensive or not well enough understood to see widespread implementation. Incremental system upgrades can return some benefits, but the more fundamental problem that they do not address is that system performance information is not measured or reported in any meaningful or systematic manner
