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.

Download Performance of Exposed Aggregate Surface of Composite Pavements at MnROAD Book in PDF, ePub and Kindle
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.

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. A composite pavement consisting of HMA over jointed plain concrete also was constructed in the field by the Illinois Tollway north of Chicago. At the Tollway, extensive field surveys were performed on 64 sections of the two types of composite pavements. This project also evaluated, improved, and further validated applicable structural, climatic, material, and performance prediction models, and design algorithms that are included in the AASHTO MEPDG and DARWin-ME, CalME, NCHRP 1-41 reflection cracking, NCHRP 9-30A rutting, and the Lattice bonding model.

Download Functional Pavement Design Book in PDF, ePub and Kindle
Functional Pavement Design is a collections of 186 papers from 27 different countries, which were presented at the 4th Chinese-European Workshops (CEW) on Functional Pavement Design (Delft, the Netherlands, 29 June-1 July 2016). The focus of the CEW series is on field tests, laboratory test methods and advanced analysis techniques, and cover analysis, material development and production, experimental characterization, design and construction of pavements. The main areas covered by the book include: - Flexible pavements - Pavement and bitumen - Pavement performance and LCCA - Pavement structures - Pavements and environment - Pavements and innovation - Rigid pavements - Safety - Traffic engineering Functional Pavement Design is for contributing to the establishment of a new generation of pavement design methodologies in which rational mechanics principles, advanced constitutive models and advanced material characterization techniques shall constitute the backbone of the design process. The book will be much of interest to professionals and academics in pavement engineering and related disciplines.

Download Texturing New Concrete Pavements Book in PDF, ePub and Kindle
Several texturing experiments on heavily traveled portland cement concrete pavements in Virginia are described. Included in the experiments were textures imparted by a heavy burlap drag, metal tines (transverse and longitudinal striations), sprinkled aggregate, mortar removal, and imprinting. All textures were imparted to concrete in the plastic state. Some of the problems encountered in achieving the desired textures are discussed. Evaluations of the effectiveness and acceptability of the textures included noise, roughness, and skid resistance studies. These studies resulted in the rejection for future use of several textures for one or more reasons. A consideration of all factors gave strong indications that the transversely tined grooves spaced 19 mm (3/4 in.) on centers and the longitudinally tined grooves spaced 19 mm (3/4 in.) in combination with transverse grooves spaced 76 mm (3 in.) are preferred.

Download Significant Findings from Full-scale Accelerated Pavement Testing Book in PDF, ePub and Kindle
"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"--
