Book Description
As the nation’s infrastructure ages, agencies at all levels are tasked with maintaining and rehabilitating their infrastructure. Sustainable engineering technologies in pavement rehabilitation, such as full-depth reclamation (FDR), could be the answer for agencies in their quest to provide taxpayers with high-quality infrastructure while being good stewards of public funds. Full-depth reclamation of asphalt pavement is a rehabilitation method that involves recycling an existing asphalt pavement and its underlying layer(s) into a new base layer. The FDR process begins with using a road reclaimer to pulverize an existing asphalt pavement and a portion of the underlying base, subbase, and/or subgrade. Usually the pulverized material is uniformly blended with an additional stabilizing material such as cement to provide an upgraded, homogeneous material. Finally, the stabilized material is compacted in place with rollers. The result is a stiff, stabilized base that is ready for a new rigid or flexible surface course. This guide introduces the FDR with cement process and discusses issues related to project selection, design, construction, and testing/quality control.

Book Description
Full depth reclamation of asphalt pavements using asphalt emulsions is a process that recycles and rejuvenates the existing asphalt pavement surface, base, and sometimes, the subgrade, providing an improved underlying structure for the new asphalt pavement. This report provides guidance, standardized plans and specifications, construction inspection best practices materials testing procedures and frequencies, a performance evaluation process, and quality assurance and quality control protocols when constructing FDR projects.

Book Description
Full-depth reclamation (FDR) is a roadway rehabilitation process that recycles the materials from deteriorated asphalt pavement, and, with the addition of portland cement, creates a new stabilized base. This guide to FDR discusses its applications, benefits, design, construction, and testing.

Book Description
This book presents the select proceedings of the 2nd International Conference on Transportation Infrastructure Projects: Conception to Execution (TIPCE 2022) and emphasizes the understanding of transportation infrastructure projects being conceptualized, designed, and executed so as to bring the desired development in the focused area. It comprises case studies from the transportation sector, construction industries, consulting agencies, and academia. These studies present the bottlenecks experienced during the implementation of the projects, from their conceptualization to their execution and the corrective measures that were incorporated to finish the work. The book will be a valuable reference for beginners, researchers, and professionals interested in construction planning and technology, infrastructure engineering, highway engineering, traffic and transportation planning and systems.

Book Description
Pavements are engineered structures essential to transportation, commerce and trade, and everyday life. In order for them to perform as expected, they must be designed, constructed, maintained, and managed properly. Providing a comprehensive overview of the subject, Pavement Engineering: Principles and Practice, Second Edition covers a wide range of topics in asphalt and concrete pavements, from soil preparation to structural design and construction. This new edition includes updates in all chapters and two new chapters on emerging topics that are becoming universally important: engineering of sustainable pavements and environmental mitigation in transportation projects. It also contains new examples and new figures with more informative schematics as well as helpful photographs. The text describes the significance of standards and examines traffic, drainage, concrete mixes, asphalt binders, distress and performance in concrete and asphalt pavements, and pavement maintenance and rehabilitation. It also contains a chapter on airport pavements and discusses nondestructive tests for pavement engineering using nuclear, deflection-based, electromagnetic, and seismic equipment. The authors explore key concepts and techniques for economic analysis and computing life-cycle cost, instrumentation for acquiring test data, and specialty applications of asphalt and concrete. The Second Edition includes more relevant issues and recently developed techniques and guidelines for practical problems, such as selection of pavement type, effect of vehicle tires, and use of smart sensors in rollers and software for drainage analysis. This book presents in-depth, state-of-the-art knowledge in a range of relevant topics in pavement engineering, with numerous examples and figures and comprehensive references to online resources for literature and software. It provides a good understanding of construction practices essential for new engineers and materials processing and construction needed for solving numerous problems.

Book Description
An increasing number of agencies, academic institutes, and governmental and industrial bodies are embracing the principles of sustainability in managing their activities and conducting business. Pavement Life-Cycle Assessment contains contributions to the Pavement Life-Cycle Assessment Symposium 2017 (Champaign, IL, USA, 12-13 April 2017) and discusses the current status of as well as future developments for LCA implementation in project- and network-level applications. The papers cover a wide variety of topics: - Recent developments for the regional inventory databases for materials, construction, and maintenance and rehabilitation life-cycle stages and critical challenges - Review of methodological choices and impact on LCA results - Use of LCA in decision making for project selection - Implementation of case studies and lessons learned: agency perspectives - Integration of LCA into pavement management systems (PMS) - Project-level LCA implementation case studies - Network-level LCA applications and critical challenges - Use-phase rolling resistance models and field validation - Uncertainty assessment in all life-cycle stages - Role of PCR and EPDs in the implementation of LCA Pavement Life-Cycle Assessment will be of interest to academics, professionals, and policymakers involved or interested in Highway and Airport Pavements.
