This book was released on 2005 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization of pavement materials in the three hierarchical design levels of the proposed mechanistic-empirical pavement design (MEPD) guide involves application of the dynamic modulus technique for asphalt concrete and the resilient modulus for unbound materials. This approach, if adequately implemented, is expected to improve the road design processes. The advance design level recommends using actual laboratory test data of the dynamic and resilient modulus determined under simulated environmental and traffic loading conditions. To circumvent the need for conducting the mechanical test in lower design levels, predictive equations and correlations established with physical properties are used to estimate the mechanistic properties needed as input to the design software. This paper examines the simplifications incorporated in the model using results of dynamic and resilient modulus tests performed at the National Research Council Canada (NRC).

This book was released on 2019 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, pavements have been designed using empirical relationships with equations derived from observed pavement failures. Recently, the design of pavements using mechanistic approaches based on known material properties of pavement materials has become an industry expectation. Specifically, a program, AASHTOWare's Pavement ME, incorporates both mechanistic and empirical understandings of pavements in order to design and predict long-term pavement distresses. This thesis aims to develop a concrete materials database for mechanical properties specific to Georgia's rigid pavements. This database includes laboratory tested values of compressive strength, Young's modulus, modulus of rupture, and ultimate shrinkage. Twelve Georgia Department of Transportation (GDOT) approved concrete mixtures using Georgia specific concrete materials were batched, tested, and analyzed for these properties. Additionally, this thesis investigates which of these properties are most critical in rigid pavement design through sensitivity analysis conducted with Pavement ME at Input Level's 1, 2, and 3. Ultimately, this study provides design recommendations for critical mechanical properties as well as guidance for which Input Level to use for the design of Georgia rigid pavements.

This book was released on 2009 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the challenges to the implementation of the mechanistic-empirical pavement design guide (MEPDG) comes from calibrating the transfer functions. This paper focuses on calibration of one of the major distress models in flexible pavement: permanent deformation or rutting. Two key aspects are critical to a successful rutting model calibration: data and method. Regarding the data, existing in-field information only provides total rut depth, which could not meet the requirement of permanent deformation in each structural layer by the MEPDG. Concerning the method, existing work either fails to address calibration factors from a holistic perspective by only focusing on individual sections separately or ignores variability inherent in those factors. In this study, layer-wise permanent deformation from instrumented pavement under accelerated pavement testing serves to accommodate the models calibration. A systematic calibration procedure is established, which globally optimizes all available information across all test sections. Through simulation and numerical optimization, optimal calibration shift factors for three typical flexible pavement materials, asphalt mixture, unbound granular base, and finegrain soil are obtained as 0.60, 0.49, and 0.84, respectively. This implies that the uncalibrated MEPDG is biased toward overprediction of rut depth. It is further suggested that a more rational result for each calibrated factor is to introduce an appropriate distribution to characterize its uncaptured variability. In addition, a case study involving using calibrated MEPDG to predict pavement performance or life indicates that (1) model calibration has a significant impact on the prediction and (2) the "fourth power law" is supported by the MEPDG.
