Nondestructive Testing to Identify Delaminations between HMA Layers


Book Description

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, describes development of nondestructive testing techniques that are capable of detecting and quantifying delaminations in HMA pavements. This NDT technique is applicable to construction, project design, and network-level assessments. This e-book contains 5 different volumes, the last 4 involving more technical descriptions of the project.




Nondestructive Testing to Identify Delaminations Between HMA Layers


Book Description

"TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R06D-RR-1: Testing to Identify Delaminations Between HMA Layers, Volume 1 describes development of nondestructive testing (NDT) techniques capable of detecting and quantifying delaminations in HMA pavements. The NDT techniques should be applicable to construction, project design, and network-level assessments. SHRP 2 Report S2-R06D-RW-2 was developed as part of SHRP 2 Renewal Project R06D that generated a sizable amount of documentation regarding the findings of evaluations and equipment development. The report for SHRP 2 Renewal Project R06D is therefore divided into five volumes. Volumes 2 through 5 provide more detailed technical information and are web-only. The topics covered in these volumes are listed below. Volume 2: Theoretical Models Volume 3: Controlled Evaluation Reports Volume 4: Uncontrolled Evaluation Reports Volume 5: Field Core Verification "--Pub. information.

Highway Research


Book Description

The 2005 Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users authorized the Dept. of Transportation (DoT) to establish a highway research program to address future challenges facing the U.S. highway system. In 2006, the Second Strategic Highway Research Program was established to conduct research in four areas -- safety, renewal, reliability, and capacity. The legislation also required a review of the program no later than three years after the first research contracts were awarded. This report provides information about the process for selecting the program's projects for funding, the projects' status, and what, if any, research was eliminated because of funding and time constraints.

Civil Engineering Applications of Ground Penetrating Radar


Book Description

This book, based on Transport and Urban Development COST Action TU1208, presents the most advanced applications of ground penetrating radar (GPR) in a civil engineering context, with documentation of instrumentation, methods and results. It explains clearly how GPR can be employed for the surveying of critical transport infrastructure, such as roads, pavements, bridges and tunnels and for the sensing and mapping of underground utilities and voids. Detailed attention is also devoted to use of GPR in the inspection of geological structures and of construction materials and structures, including reinforced concrete, steel reinforcing bars and pre/post-tensioned stressing ducts. Advanced methods for solution of electromagnetic scattering problems and new data processing techniques are also presented. Readers will come to appreciate that GPR is a safe, advanced, non destructive and noninvasive imaging technique that can be effectively used for the inspection of composite structures and the performance of diagnostics relevant to the entire life cycle of civil engineering works.







Accelerated Pavement Testing to Transport Infrastructure Innovation


Book Description

This volume gathers the latest advances, innovations, and applications in the field of accelerated pavement testing (APT), presented at the 6th International Conference on Accelerated Pavement Testing, in Nantes, France, in April 2022. Discussing APT, which involves rapid testing of full-scale pavement constructions for structural deterioration, the book covers topics such as APT facilities, APT of asphalt concrete and sustainable/innovative materials, APT for airfield pavements, testing of maintenance and rehabilitation solutions, testing of smart and multi-functional pavements, data analysis and modeling, monitoring and non-destructive testing, and efficient means of calibrating/developing pavement design methods. Featuring peer-reviewed contributions by leading international researchers and engineers, the book is a timely and highly relevant resource for materials scientists and engineers interested in determining the performance of pavement structures during their service life (10+ years) in a few weeks or months.




Using Existing Pavement in Place and Achieving Long Life


Book Description

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, focuses on improving the ability of highway agencies to design and construct long-lasting highway projects with minimal disruption to the traveling public.




Nondestructive Testing of Materials and Structures


Book Description

Condition assessment and characterization of materials and structures by means of nondestructive testing (NDT) methods is a priority need around the world to meet the challenges associated with the durability, maintenance, rehabilitation, retrofitting, renewal and health monitoring of new and existing infrastructures including historic monuments. Numerous NDT methods that make use of certain components of the electromagnetic and acoustic spectrum are currently in use to this effect with various levels of success and there is an intensive worldwide research effort aimed at improving the existing methods and developing new ones. The knowledge and information compiled in this book captures the current state of the art in NDT methods and their application to civil and other engineering materials and structures. Critical reviews and advanced interdisciplinary discussions by world-renowned researchers point to the capabilities and limitations of the currently used NDT methods and shed light on current and future research directions to overcome the challenges in their development and practical use. In this respect, the contents of this book will equally benefit practicing engineers and researchers who take part in characterization, assessment and health monitoring of materials and structures.
