Significant advances were made in recent years in nondestructive evaluation (NDE) technologies’ efficiency for detecting and characterizing deterioration in bridge decks, including advances in automation of NDE data collection, analysis, and interpretation. Those advances enable more extensive and more frequently implemented data collection that will lead to a more objective description of the current condition and a more precise prediction of the progression of deterioration. Also, complementary use of multiple NDE technologies may assist in the identification of likely causes of deterioration. As such, the NDE data are becoming essential for the effective and economic management of bridges, concrete bridge decks in particular. Still, to develop NDE based deterioration and predictive models on both project and network levels, data from multiple surveys over a more extended period are lacking. It has also been shown that the bridge deck performance varies widely, even between bridges that are very close in age and that have similar traffic loads, designs, and climate conditions. It indicates that deterioration processes, since they are a result of multiple inputs and actions, are inherently complex. Therefore, other influences require an examination to provide complete answers regarding disparate bridge deck performance. Complementary use of NDE, structural health monitoring (SHM), and other technologies for local and global assessment of bridges opens opportunities for providing answers to the development of realistic deterioration models and comprehensive evaluation of factors influencing concrete bridge deck performance. The paper concentrates on the discussion of merging of the technologies in the achievement of two specific objectives: assessment of the influence of bridge superstructure on the deck performance using large mobile shakers, and the use of accelerated structural testing for fast and comprehensive development of an understanding of deterioration processes in concrete bridge decks.

The Automated Nondestructive Evaluation and Rehabilitation System (ANDERS) aims to provide a uniquely comprehensive tool that will transform the manner in which bridge decks are assessed and rehabilitated. It is going to be achieved through: 1) much higher evaluation detail and comprehensiveness of detection at an early stage deterioration, 2) comprehensive condition and structural assessment at all stages of deterioration, and 3) integrated assessment and rehabilitation that will be minimally invasive, rapid and cost effective. ANDERS is composed of three physical systems that merge novel NDE technologies together with novel intervention approaches to arrest the deterioration processes. These technologies are incorporated within a series of human-operated and robotic vehicles to allow rapid, comprehensive application across large populations of bridges. To perform assessments, ANDERS is equipped with two complimentary nondestructive approaches. The first, Multi-Modal Nondestructive Evaluation (MM-NDE) System aims to identify and characterize localized deterioration with a high degree of resolution. The second, global structural assessment system named STAR aims to capture global structural characteristics and identify any appreciable effects of deterioration on a bridge structure. Output from these two approaches will be merged through a novel Automated Structural Identification (Auto St-Id) approach that constructs, calibrates, and utilizes simulation models to assess the overall structural vulnerability and capacity. These two systems comprise the assessment suite of ANDERS and directly inform the Nondestructive Rehabilitation (NDR) System. The NDR System leverages robotics for the precision and rapid delivery of novel materials capable of halting the early-stage deterioration identified. The paper covers the details of the three ANDERS components developed through the support from National Institute of Standards and Technology-Technology Innovation Program (NIST-TIP). Specifically, the paper will provide a description of the components, their principle of operation and applications, and describe how the components work together.
