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.

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.
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.
