“…The information gathered during the monitoring can be used as decision support by the authorities (public or private) deputed to the construction and maintenance of the road infrastructures to improve the management process, or by the users to optimize their trips in terms of travel time, costs, safety, and consumptions. Infrastructure monitoring can be carried out using traditional destructive testing (DT) or innovative nondestructive testing (NDT, see e.g., [44]). Usually, DT is the most used because of the fact that (i) it is based on wellestablished and accurate methods, (ii) it derives the characteristics of the road pavement from samples of the pavement (e.g., after coring), (iii) technology requirements and worker's knowledge and skills (e.g., to carry out the measurements, or to process the data) are usually already in place.…”

Transportation systems are gradually changing. Innovative solutions are provided by automotive industries, construction firms, computer-aided pavement management systems, sensor-based structural health monitoring (SHM) systems, and international regulations. This calls for efforts and studies aiming at finding a trade-off between the ever-growing request of innovation (smart cities), and the never-ending depletion of resources and energy. Energy savings in road infrastructures can be pursued through: 1) construction process optimization; 2) traffic management improvement; 3) vehicle optimization; 4) recycling and reuse of construction materials; 5) innovative materials; 6) energy harvesting; 7) smart roads; 8) maintenance and rehabilitation optimization through SHM methods and technologies. The objective of the study is to set up an innovative SHM method aiming at achieving energy savings in transportation in terms of Pavement Management System (PMS) optimization. The new method here setup was implemented through an experimental investigation. A microphone was placed on different road pavements, impulse loads were produced by a Light weight Deflectometer, LWD, and vibro-acoustic signals were recorded and analyzed in the pursuit of assessing the structural condition of the pavement. Using this knowledge to improve the management process of transportation infrastructures, it is expected that safer, more resilient, and less energy-consuming assets will be provided.

“…The experimental dispersion characteristics of the generated surface waves in the layered pavement structure, typically expressed in the form of dispersion curves, contain the stiffness profile information. The stiffness profile of the tested pavement site is back calculated by matching the experimental dispersion curve to theoretical counterparts calculated by forward modelling for assumed stiffness profiles (Lin & Ashlock, 2011Lin, Ashlock, & Williams, 2016;Nazarian, 1984;Park, Miller, & Xia, 1998;Ryden, Ulriksen, Park, & Miller, 2002). Surface wave tests in this study were carried out using the multichannel simulation with one receiver (MSOR) test method proposed by Ryden et al (2002) and the MSOR testing system developed by Lin andAshlock (2011, 2015).…”

Abstract. Reflective cracking is a common type of pavement distress, which manifests as cracks in an underlying layer propagating through to the surface of a pavement structure. To minimize reflective cracking of asphalt layers in composite pavements, four treatments are commonly used: standard/full rubblization, modified rubblization, crack and seat, and rock interlayer. The four types of treatment were evaluated to determine their effectiveness in mitigating reflective cracking via non-destructive Falling Weight Deflectometer tests and Surface Wave Method tests to measure layer modulus, along with field pavement performance surveys. It is found that moduli measurements from Surface Wave Method tests have reduced uncertainty comparing to those from Falling Weight Deflectometer tests, (2) the moduli of thin rock interlayers were captured by Surface Wave Method, but missed by Falling Weight Deflectometer. In addition, the Surface Wave Method results show that (1) crack and seat treatments provide the highest moduli, followed by modified rubblization, and (2) standard rubblization and rock interlayers provide moduli that are slightly lower than the other two treatments. Pavement performance survey was also conducted concurrently with the in-situ modulus tests. Based on the results of this study, modified rubblization and rock interlayer treatments are recommended for mitigation of reflective cracking.

“…Modulus can directly reflect the bearing capacity of pavement structure and judge the quality of pavement [8]. Lin et al developed a quality assurance procedure to correct the in situ moduli at different field temperatures to a common reference temperature using a fitting function from experimental data for quality assurance and using master curves from laboratory dynamic modulus tests for quality assurance, which can be used for an assessment of the actual pavement performance [9]. Quansah et al implemented the traffic back-calculation technique through the use of a dynamic cone penetrometer as the effective tool in the assessment of subsurface conditions and evaluation of the structural capacity of a Coca-Cola factory road in Ghana [10].…”

The traditional evaluation method of construction quality for asphalt pavement has gradually lagged behind the pace of development of the road industry. Big data, Internet of Things (IoT), and intelligent sensing technology have been reflected in the field of road engineering, but these technologies also have technical shortcomings in terms of applicability, durability, real-time performance, and portability in practice. To provide a new method for construction quality evaluation of asphalt pavement, this study developed an intelligent sensing aggregate (ISA) with low cost and high precision based on the 3D printing and Internet of Things (IoT) technology. Based on the laboratory test and field test, the sensing characteristics, high-temperature resistance, and mechanical properties of ISA are analyzed to verify the reliability of ISA. Through the quantitative analysis of ISA perception data, the Driving Perception Index (DPI) is proposed. By analyzing the quantitative correlation between the spatial angle of ISA and the compaction degree, the quantitative correlation between the DPI, International Roughness Index (IRI), and the deflection value, the evaluation standard of construction quality for asphalt pavement is established. The result shows that the best baud rate for ISA is 9600 bps, and the corresponding data transmission distance is 350 m. In the range of 6 m, the cars, trucks, trailers, and buses can be perceived by ISA. The maximum operating temperature of ISA is up to 200°C. Embedding ISA into asphalt mixture has no significant effect on original gradation of asphalt mixture. The established evaluation standard of construction quality for asphalt pavement takes into account the compaction quality, the requirements of bearing capacity, and the driving comfort of asphalt pavement, which is suitable for expressway and first-class highway.
