2001 WisDOT Specifications - Construction Note

For the past several years, Marquette University has been conducting a research study for WisDOT on tining patterns to reduce the objectionable tire/pavement whine. During the research study, WisDOT issued Construction Notes to implement the interim results of the research rather than tine the pavement according to Subsection 415.5.9.6.3 of the Standard Specifications. In the completed study, Marquette University has determined that a skewed, randomly spaced, transversely tined surface results in the lowest levels of pavement whine while retaining the favorable friction characteristics achieved under the current specifications. The overall noise level is not reduced by skewed randomly tined surfaces. The research study wasn’t completed in time to include the recommended tining requirements in the bidding documents for 2001 construction projects. However, Wisconsin Concrete Pavement Association (WCPA) members are aware of the findings of the research study. All WCPA member contractors are intending to use the randomly spaced tining rake, meeting the study recommendations, during the 2001 construction season. Therefore, WisDOT is implementing the research study recommendations on randomly spaced rake for the 2001 construction season with this Construction Note

Marquette Interchange Installation Report

Task three of the Perpetual Pavement Instrumentation Plan for the Marquette Interchange Project called for the installation of the various pavement sensors, data acquisition system, and various other components of the system outlined in the project proposal. The MU-TRC research team has successfully completed the installation of these various components of the system. This report fulfills the requirement of the installation report from task three in the project plan. This report is organized to describe in detail each specific component of the system. Most, but not all, of these details are written in the order they were completed. Not every activity described in this report is associated with the installation of a particular component but have been included because they are thought to have a significant impact on the methodologies and procedures used. This report is intended to describe the installation processes in as much detail as possible. To help accomplish this, many figures, pictures, data, and video were acquired / developed; many of which have obviously been filtered out and only the most pertinent included. All of this material will be compiled into a single archive and will be submitted to WHRP. This report was also written to explain and document any blunders, failures, and/or deviations from any proposed designs regarding this particular project or the Marquette Interchange project itself. These types of details are given so future research can learn from these experiences and make improvements upon them

Public Perceptions of the Midwest’s Pavements - Iowa - Phase II (State Wide Survey Report)

This report covers Phase II of a three-phase pooled-fund project in Wisconsin, Iowa and Minnesota, to determine the perception/satisfaction levels of the driving public and how they correlate with the states’ physical data bases used to determine priorities for pavement improvements on rural, two-lane highways. In addition, policy issues of trust and improvement trade-offs are addressed. In Phase I, six focus groups were conducted in each state to determine the beliefs and issues about pavements that could be used to draft statewide questionnaires. Focus groups were held during the last half of 1996 in all three states. From the focus groups a language used by the public to describe and differentiate ruts, grooves, tining and other pavement characteristics was developed so that the Phase II telephone surveys could help explain terms when needed. Phase II began in late 1996, involving a lengthy process to arrive at a questionnaire that satisfied all three states. Phase II consisted of a statewide telephone survey of at least 400 randomly- selected drivers 18 years or older in each of the three states. Actual pretests of the statewide surveys occurred in early fall, 1997, with approximately 30 to 40 surveys in each state. The three statewide surveys were administered in Fall, 1997, and completed in mid December, 1997 in Wisconsin, and early January, 1998 in Iowa and Minnesota. Comprehensive analysis of the data has been underway since then
