An increasing number of agencies, academic institutes, and governmental and industrial bodies are embracing the principles of sustainability in managing their activities. Life Cycle Assessment (LCA) is an approach developed to provide decision support regarding the environmental impact of industrial processes and products. LCA is a field with ongoing research, development and improvement and is being implemented world-wide, particularly in the areas of pavement, roadways and bridges. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 contains the contributions to the International Symposium on Pavement, Roadway, and Bridge Life Cycle Assessment 2020 (Davis, CA, USA, June 3-6, 2020) covering research and practical issues related to pavement, roadway and bridge LCA, including data and tools, asset management, environmental product declarations, procurement, planning, vehicle interaction, and impact of materials, structure, and construction. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 will be of interest to researchers, professionals, and policymakers in academia, industry, and government who are interested in the sustainability of pavements, roadways and bridges.

Pack: Book and CD Internationally, full-scale accelerated pavement testing, either on test roads or linear/circular test tracks, has proven to be a valuable tool that fills the gap between models and laboratory tests and long-term experiments on in-service pavements. Accelerated pavement testing is used to improve understanding of pavement behavior, and evaluation of innovative materials and additives, alternative materials processing, new construction techniques, and new types of structures. It provides quick comparisons between current and new practice and the ability to rapidly validate and calibrate models with quality data, with minimal risk at relatively low cost. Advances in Pavement Design through Full-scale Accelerated Pavement Testing is a collection of papers from the 4th International Conference on Accelerated Pavement Testing (Davies, CA, USA, 19-21 September 2012), and includes contributions on a variety of topics including: - Overview of Accelerated Pavement Testing - Establishment of New Accelerated Pavement Testing Facilities - Review of the Impact of Accelerated Pavement Testing Programs on Practice - Instrumentation for Accelerated Pavement Testing - Accelerated Pavement Testing on Asphalt Concrete Pavements - Accelerated Pavement Testing on Portland Cement Concrete Pavements - Accelerated Pavement Testing to Evaluate Functional Performance - Relating Laboratory Tests to Performance using Accelerated Pavement Testing - Development and Calibration of Empirical and Mechanistic-empirical Pavement Design Procedures and Models - Benefit-cost Analysis of Accelerated Pavement Testing Advances in Pavement Design through Full-scale Accelerated Pavement Testing will be useful to academics and professionals involved in pavement engineering.

Internationally, much attention is given to mechanistic pavement analysis, design and rehabilitation, their geotechnical aspects and the experimental determination of the necessary material model parameters. This conference on the Advanced Characterisation of Pavement and Soil Engineering (Athens, Greece, 20-22 June 2007) provided a forum for discussion of recent developments and research results. Topics included: - Constitutive Modeling - Experimental Laboratory Material Characterization - Finite Element Simulation - Subgrade Testing, Evaluation and Modeling - Open Graded HMA and Moisture Damage - Field Measurements and In Situ Characterization - Nondestructive Measurement Techniques and Analysis Tools - Accelerated Testing - Hot-Mix Asphalt design - Pavement Management and Design - Measurement and Modeling of Pavement Cracking - Permanent Deformation - Pavement Interface Characteristics - Innovative Pavement Materials and Interface Systems - Surface Characterization & Tire-Surface Interaction - Concrete Pavements - Chemo-Physical Processes - Environmental Issues Related to Pavements - Case Studies - Rail-track Assessment and Rehabilitation - Railroad Ballast Characterization Advanced Characterisation of Pavement and Soil Engineering is particularly of interest to academics, researchers and practitioners involved in computational simulation, experimental characterization and field testing for prediction of short and long term performance of various types of pavement.

Bituminous materials are used to build durable roads that sustain diverse environmental conditions. However, due to their complexity and a global shortage of these materials, their design and technical development present several challenges. Advanced Testing and Characterisation of Bituminous Materials focuses on fundamental and performance testing of binders and asphaltic mixtures. The contributions demonstrate that modern experimental material characterization techniques, sophisticated constitutive modeling, and innovative design provide appropriate tools for pavement performance prediction. The book is of interest to academics and engineers in pavement and road engineering.
