Book Description
Seasonal variation of temperature and moisture cause considerable changes in the load-carrying capacity of pavements in geographical areas subject to extreme freeze/thaw conditions. Pavement engineers in these areas must be able to quantify the variation in the load-carrying capacity of a pavement in order to design it adequately. The Seasonal Monitoring Program (SMP) of the Long Term Pavement Performance (LTPP) study of the U.S.A. Federal Highway Administration (FHWA) is monitoring seasonal variations in Falling Weight Deflectometer (FWD) deflections, air temperature, rainfall, soil temperature, moisture content, and soil electrical resistance at numerous sites across North America. The present study relates changes in pavement load carrying capacity represented by the pavement layer resilient moduli to selected environmental factors on the SMP site near Oak Lake, Manitoba. The most significant environmental parameters causing seasonal variation in pavement layer resilient moduli are identified as surface temperature (asphalt layer) and Thawing Index (base and subgrade layers). The examination of the material properties of this single pavement site during any time of the year is an important first step towards the adoption of mechanistic pavement design and rehabilitation procedures at the Manitoba Department of Highways and Transportation. For the covering abstract of this conference see IRRD number 872978.

Book Description
Inspired from the legacy of the previous four 3DFEM conferences held in Delft and Athens as well as the successful 2018 AM3P conference held in Doha, the 2020 AM3P conference continues the pavement mechanics theme including pavement models, experimental methods to estimate model parameters, and their implementation in predicting pavement performance. The AM3P conference is organized by the Standing International Advisory Committee (SIAC), at the time of this publication chaired by Professors Tom Scarpas, Eyad Masad, and Amit Bhasin. Advances in Materials and Pavement Performance Prediction II includes over 111 papers presented at the 2020 AM3P Conference. The technical topics covered include: - rigid pavements - pavement geotechnics - statistical and data tools in pavement engineering - pavement structures - asphalt mixtures - asphalt binders The book will be invaluable to academics and engineers involved or interested in pavement engineering, pavement models, experimental methods to estimate model parameters, and their implementation in predicting pavement performance.

Book Description
Recent advances in flexible pavement design have prompted agencies to move toward the development and use of mechanistic-empirical (M-E) design procedures. The purpose of this paper is to analyze seasonal trends in flexible pavement layer moduli in order to calibrate a mechanistic-empirical design procedure specific to Minnesota. The relationships investigated were between climate factors, surface and subsurface conditions, and pavement material properties. The results presented focus on the base and subgrade layers and show that the layer moduli vary with the state of moisture in the pavement. The data used to develop this approach were collected from four flexible pavement Long Term Pavement Performance Seasonal Monitoring Program sites (LTPP SMP) and the Minnesota Road Research Project (Mn/ROAD). Temperature data are used in this study to characterize the severity of a winter and to approximate the onset of freezing and thawing cycles. Finally, seasonal trends in pavement layer moduli were quantified for use in an M-E design of flexible pavements.
