Book Description
This study was approved by the CDOT's Research Implementation Committee as a high priority research with the goal of improving the accuracy of the existing and forecasted traffic loads of CDOT's highway network. The overall scope of this project involved examination of those resources directly related to the current statewide ESAL classification system and the generation of this final report discussing the research and analysis conducted and recommendation of procedures required for CDOT to develop and implement a more site-specific ESAL classification system. In this study Nichols Consulting Engineers (NCE) analyzed all available CDOT permanent and portable weigh-in-motion (WIM) data.

Book Description
For a given road segment, accurate estimates of current and projected traffic [in terms of Equivalent Single Axle Loads (ESALs)] can result in significant cost savings, either from the standpoint of initial construction cost or future maintenance and rehabilitation cost. The primary objective of this project is to prepare a new ESAL design table for Arizona's highway network. This new table is based on analysis of current traffic data collection procedures, traffic forecasting methodology, and ESAL development procedures, including the assignment of traffic ESAL levels to the various highway segments.

Book Description
This book includes a collection of research and practical papers aiming with key priority for improving the infrastructural sustainability for our well-being and day-to-day lives through novel developments. The united efforts through new developments in material, design, construction, maintenance, and testing of pavements from all over the world are taken under one umbrella. Topics include issues related to civil infrastructure such as the use of construction waste, recycled aggregates, service life prediction of pavements, mechanical behavior of SMA, control measures of ready mixed concrete, determination of landslide high-risk areas, Simulation of rock hydraulics in rock joint, sustainable planning for provision of basic infrastructural facilities in rural areas. It is anticipated that this book will support decisions regarding the optimal management and maintenance of civil infrastructures to support a more resilient and sustainable environment for infrastructure users.

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
In May 2000, the Colorado Department of Transportation (CDOT) requested a forensic study of a project located on I-24 north of Denver. The request was made because, within a year of the 1997 overlay, longitudinal cracking appeared in the surface. Transverse cracks were attributed to reflective cracking. However, the longitudinal cracks appeared to be surface initiated. In October 2000, a forensic team reviewed the project and established a sampling and testing plan to take cores from the roadway. Based on data analysis of the cores, the higher than expected in-place air voids, the low effective asphalt, and segregation within the mat, all contributed to the early cracking.

Book Description
In 2000, a forensic evaluation was conducted on a project that was exhibiting early longitudinal cracking near the wheel paths. A team of national asphalt experts conducted this forensic evaluation. The forensic team concluded that the cracking on the project was surface initiated cracking and was caused by a number of contributing factors. One of the contributing factors to the early distress that was identified by the experts were the pockets of segregation that were observed at the bottom of the surface lift but were not apparent on the surface. The object of this study was to determine the extent of "top-down cracking" in Colorado, what causes it, how can it be prevented, if it occurs how is the distress treated, and how quickly does the distress need to be treated.
