This book was released on 2012 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper summarizes the construction and early performance assessment of an exposed aggregate surface on a composite pavement test cell (cell 72) at MnROAD. Although exposed aggregate surfaces and composite pavement systems have become extremely popular in Europe, they are a relatively new concept in the United States. The performance of the exposed aggregate surface is compared to that in the two other composite pavement cells at MnROAD: cell 70, hot mix asphalt (HMA) over a recycled aggregate concrete, and cell 71, diamond grind concrete over recycled aggregate concrete. The strength, tire pavement noise (on board sound intensity), sound absorption, friction, texture, and international roughness index were tested. The results suggest that the exposed aggregate concrete surface does not provide significant noise reduction. Innovative diamond grinding of composite pavements might be beneficial for noise reduction. Exposed aggregate surfacing can provide more than adequate friction for driver safety, but it does not show any improvement relative to typical HMA or diamond ground surfaces. Exposed aggregate surfaces have a texture (or mean profile depth) similar to that of traditional diamond ground surfaces but might be detrimental to the ride quality. Continued monitoring of these test cells will aid the development of a wide understanding of exposed aggregate surfaces and composite pavements needed for more effective design and accurate service life models.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the construction and early performance assessment of three composite (new, multi-layer, construction) test cells at the MnROAD: HMA over a recycled aggregate concrete; diamond grind concrete over recycled aggregate concrete; and exposed aggregate concrete over a low cost concrete. The compilation of this report is strictly a MnDOT activity that documents construction and instrumentation of concrete cells at our MnROAD facility and should not be misconstrued for a SHRP 2 activity. Strength, on board sound intensity, sound absorption, friction, texture and international roughness index were tested to better understand the performance of these, pavement types. Results suggest that the exposed aggregate concrete surface does not provide significant noise reduction. Exposed aggregate surfacing can provide more than adequate friction for skid resistance and safety. Overall, however, these two lift concrete pavements proved to address issues such as high cost of virgin aggregates and high trucking costs for areas that don't have quality aggregates to use. Continued monitoring of these test cells will help develop the extensive understanding of composite pavements needed for effective design and accurate service life models.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes an extensive data collection effort, spanning five years, and the subsequent data analysis to evaluate the performance of surface characteristics on portland cement concrete pavements that have been diamond ground with various grinding configurations. The data collected were analyzed and evaluated to observe the longterm performance of the surface characteristics of noise, friction, texture, and ride quality. In addition to the basic analysis and comparison of the performance with respect to the control cell, several other studies were performed such as the correction of noise data with ambient air temperatures at the individual third-octave frequencies and evaluation of trends in the data using various statistical analysis methods. In addition, other surface characteristics were measured to provide a baseline for comparison with potential future measurements, including rolling resistance and advanced texture characteristics. The surface characteristics evaluated indicated immediate changes were effected due to the grinding activity, and that over time (and due to the application of repetitive traffic) these immediate effects were diminished somewhat, in most cases. Based on the immediate and long-term performance of the various grinding configurations, recommendations are made in the report regarding the use of the configurations and areas suggested for further research.

Book excerpt: "Composite pavements have proved in Europe and the United States to have long service life with excellent surface characteristics, structural capacity, and rapid renewal when needed. Based on statistics compiled in 2000, approximately 30% of the urban interstate system and just over 20% of the rural interstate system is classified as "composite" pavement. In most cases the composite pavements are the result of maintenance and rehabilitation activities and not intentionally designed new composite pavement systems. This project developed the guidance needed to design and construct new composite pavement systems. The research determined the behavior, properties, and performance for both HMA/PCC and the PCC/PCC composite pavements under many climate and traffic conditions. Experimental composite pavements were constructed at MnROAD in Minnesota and the University of California Pavement Research Center at Davis, where the pavements were instrumented and monitored under climate and heavy traffic loadings.

The current DARWin-ME overlay design procedure for HMA/PCC and a special R21 version of the Mechanistic-Empirical Pavement Design Guide (MEPDG [v. 1.3000:R21]) can be used for new PCC/PCC composite pavements. The key to the sustainable features of new composite pavements is the ability to use higher levels of recycled materials in the lower concrete layer. Additionally, the thickness of the lower concrete layer can be reduced when considering the insulating effect of the top pavement surface. Intentionally designed and constructed composite pavements will help highway agencies meet the goal of building economical, sustainable pavement structures that use higher levels of recycled materials and locally available materials"--Foreword.

Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 433: Significant Findings from Full-Scale Accelerated Pavement Testing documents and summarizes significant findings from the various experimental activities associated with full-scale accelerated pavement testing (f-sAPT) programs that have taken place between 2000 and 2011. The report also identifies gaps in knowledge related to f-sAPT and where future research may be needed. NCHRP Synthesis 433 is designed to expand the f-sAPT base of knowledge documented in NCHRP Syntheses 325 and 235, both with the same title of Significant Findings from Full-Scale Accelerated Pavement Testing. f-sAPT is the controlled application of a wheel loading, at or above the appropriate legal load limit, to a pavement system to determine pavement response in a compressed time period. The acceleration of damage is achieved by one or more of the following factors: increased repetitions, modified loading conditions, imposed climatic conditions, and thinner pavements with a decreased structural capacity which have shorter design lives"--

Available in PDF, EPUB and Kindle. Book excerpt: "Long Term Durability of Structural Materials" features proceedings of the workshop held at Berkeley, CA in October, 2000. It brought together engineers and scientists, who have received grants from the initiative NSF 98-42, to share their results on the study of long-term durability of materials and structures. The major objective was to develop new methods for accelerated short-term laboratory or in-situ tests which allow accurate, reliable, predictions of the long-term performance of materials, machines and structures. To achieve this goal it was important to understand the fundamental nature of the deterioration and damage processes in materials and to develop innovative ways to model the behavior of these processes as they affect the life and long-term performance of components, machines and structures. The researchers discussed their approach to include size effects in scaling up from laboratory specimens to actual structures. Accelerated testing and durability modeling techniques developed were validated by comparing their results with performance under actual operating conditions. The main mechanism of the deterioration discussed included environmental effects and/or exposure to loads, speeds and other operating conditions that are not fully anticipated in the original design. A broad range of deterioration damage, such as fatigue, overload, ultraviolet damage, corrosion, and wear was presented. A broad range of materials of interest was also discussed, including the full spectrum of construction materials, metals, ceramics, polymers, composites, and coatings. Emphasis was placed on scale-dependence and history of fabrication on resulting mechanical behavior of materials.

This book was released on 2012 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research report discusses the planning necessary for the proper development, acquisition, installation, and maintenance of an effective health monitoring network for transportation infrastructure systems. A comprehensive literature search was conducted, and the materials were compiled into a database, reviewed, and synthesized. Data elements vital for maintaining safe and functional transportation infrastructures were identified and discussed for bridge structures, pavements, and geotechnical structures. Moreover, the steps necessary for planning an instrumentation system for a particular structure are presented. Sample design plans for the transportation infrastructure systems that are typically constructed in Wisconsin were obtained from WisDOT, and suggested instrumentation plans were developed for these transportation systems. One of the objectives of the research project is to identify urban freeway construction projects that could efficiently serve as hosts for an infrastructure health monitoring (IHM) instrumentation testbed. Major current and near-future construction projects in Wisconsin were identified and critically evaluated to identify a candidate project to host the IHM testbed. Among the candidates, the Zoo Interchange reconstruction project is recommended for hosting the infrastructure health monitoring testbed. Cost estimates based on current market prices are provided for the instrumentation plans developed for IHM of bridge structures, pavements, and geotechnical structures. To provide an example of using IHM data in applications, archived data from the Marquette Interchange instrumentation project was used to develop vehicle wander patterns and load spectra data, both in the form needed to conduct a mechanistic appraisal of the pavement structure using the DARWin ME software. The research team designed and conducted an IHM survey of state highway agencies in the U.S. and Canada. The survey showed that 46 percent of state DOTs have implemented health monitoring applications for transportation infrastructure. The survey also identified the impediments facing state DOTs in implementing IHM systems.
