Transverse Cracking of Asphalt Pavements, HR-1040, Summary Report, 1982

This report summarizes the analysis of transverse cracking in asphalt pavement by a five state study team from Iowa, Kansas, Nebraska, North Dakota, and Oklahoma. The study was initiated under the sponsorship of the Federal Highway Administration and four evaluation conferences were held during the course of the study. Each state conducted a crack inventory on their asphalt pavement. An effort was made to correlate this inventory with numerous factors that were considered to be pertinent to the cracking problem. One state did indicate that there was a correlation between transverse cracking severity and the subsurface geology. The other states were unable to identify any significant factors as being the primary contributors. The analysis of the problem was divided into, (1) mix design, (2) maintenance, and (3) 3R rehabilitation. Many potential factors to be considered were identified under each of these three study divisions. There were many conclusions as to good and bad practices. One major conclusions was that a more effective crack maintenance program with early sealing was essential. Some new practices were suggested as potentially more cost effective in design, construction and maintenance. The interchange of methods and procedures by individual states yielded benefits in that other states selected practices that would be an improvement to their program.

Electronic Construction Collaboration System – Final Phase, SPR RB02-008, 2014

This phase of the research project involved two major efforts: (1) Complete the implementation of AEC-Sync (formerly known as Attolist) on the Iowa Falls Arch Bridge project and (2) develop a web-based project management system (WPMS) for projects under $10 million. For the first major effort, AEC-Sync was provided for the Iowa Department of Transportation (DOT) in a software as a service agreement, allowing the Iowa DOT to rapidly implement the solution with modest effort. During the 2010 fiscal year, the research team was able to help with the implementation process for the solution. The research team also collected feedback from the Broadway Viaduct project team members before the start of the project and implementation of the solution. For the 2011 fiscal year, the research team collected the post-project surveys from the Broadway Viaduct project members and compared them to the pre-project survey results. The result of the AEC-Sync implementation in the Broadway Viaduct project was a positive one. The project members were satisfied with the performance of AEC-Sync and how it facilitated document management and transparency. In addition, the research team distributed, collected, and analyzed the pre-project surveys for the Iowa Falls Arch Bridge project. During the 2012 fiscal year, the research team analyzed the post-project surveys for the Iowa Falls Arch Bridge project AEC-Sync implementation and found a positive outcome when compared to the pre-project surveys. The second major effort for this project involved the identification and implementation of a WPMS solution for smaller bridge and highway projects. During the 2011 fiscal year, Microsoft SharePoint was selected to be implemented on these smaller highway projects. In this year, workflows for the shop/working drawings for the smaller highway projects specified in Section 1105 of the Iowa DOT Specifications were developed. These workflows will serve as the guide for the development of the SharePoint pages. In order to implement the Microsoft SharePoint pages, the effort of an integrated team proved to be vital because it brought together the expertise required from researchers, programmers, and webpage developers to develop the SharePoint pages.
