5.1 Real-time detection and assessment of cracks and other flaws in concrete structures is of great importance. A number of methods have been developed and standardized in recent decades for non-destructive evaluation of concrete structures as well as methods for in-place evaluation of concrete...
1.1 This test method covers several ground penetrating radar (GPR) evaluation procedures that can be used to evaluate the condition of concrete bridge decks overlaid with asphaltic concrete wearing surfaces. These procedures can also be used for bridge decks overlaid with portland cement concrete...
1.1 This test method determines the quasi-static longitudinal tensile strength and elongation properties of fiber reinforced polymer matrix (FRP) composite bars commonly used as tensile elements in reinforced, prestressed, or post-tensioned concrete. Note 1: Additional procedures for determining...
5.1 Concepts-This guide summarizes the equipment, field procedures, and data processing methods used to interpret geologic conditions, and to identify and provide locations of geologic anomalies and man-made objects with the GPR method. The GPR uses high-frequency EM waves (from 10 to 3000 MHz) to...
INTRODUCTION Application of wet lay-up Fiber reinforced polymer (FRP) systems in the repair industry is well accepted. These applications include structural strengthening of structures such as parking garages, buildings, bridges, etc. which have experience some form of structural deficiency, many...
Purpose: In accordance with the authority in DoD Directive (DoDD) 5134.01 and DoD Instruction (DoDI) 4140.01, this issuance: • Establishes policy and assigns responsibilities for the management and disposition of MPPEH, material documented as an explosive hazard (MDEH), and material documented as...
5.1 The electrical conductivity of concrete is primarily influenced by the presence of moisture. Other factors, which affect the electrical continuity of concrete structures, include the following: 5.1.1 Presence of metal rebars, 5.1.2 Cement content and type, 5.1.3 Aggregate types, 5.1.4...
Bridges play important role in modern infrastructural system. This book provides an up-to-date overview of the field of bridge engineering, as well as the recent significant contributions to the process of making rational decisions in bridge design, assessment and monitoring and resources...
Scope of the Report This NACE report contains information about materials that provide a corrosion-resistant alternative to plain carbon steel reinforcing bar (rebar), known also as black bar. Throughout this report the term "carbon steel bar" is used to refer to the plain carbon steel...
4.1 This guide provides a useful summary to the selection and use of procedures for testing coating powders and powder coatings. It is applicable to both thermoplastic and thermoset coatings, unless indicated otherwise. By design this guide does not purport to address test methods or procedures...

1.1 These test methods cover instructions for making a variety of tests for the strength of the adhesive bond developed between a steel anchor and the surface of a hole in concrete or masonry (including masonry units and mortar joints) and for assessing the effects on such bond of a variety of...
INTRODUCTION Three-dimensional finite element method (FEM) calculations for concrete structures are now commonplace in many applications. Common applications range from academic studies of structural behaviors under transient loads to informing designs for new structures or retrofits. The objective...
1.1 This test method covers several ground penetrating radar (GPR) evaluation procedures that can be used to evaluate the condition of concrete bridge decks overlaid with asphaltic concrete wearing surfaces. These procedures can also be used for bridge decks overlaid with portland cement concrete...
4.1 This standard guide applies to concrete that is still in place with a defined geometry and known, documented history. 4.2 It is not intended for use on concrete that has already been rubbelized where it is difficult to measure the radiation levels and not easy to remove surface contamination to...
Provides guidelines on field inspection of rust on reinforcing steel (rebar). Includes a basic overview on corrosion, surface contaminants, mill scale and bond strength of rusted rebar
