“…Taking the AC-13 mix as an example, node #379 at the receiving end on the ultrasonic propagation path was selected and its time-displacement curve was obtained. The time that the first wave of ultrasonic propagation was detected was 5.069 E-5 s. Also, the total height of AC was 0.15 m, so the ultrasonic wave velocity can be calculated by using the relationship of time, distance, and velocity, as given in Equation (5). The final calculated velocity was 2958 m/s.…”

“…As the dynamic moduli of AC samples measured in the laboratory were much lower than those calculated by ultrasonic test results, the simulated results of wave velocity were definitely smaller in this case. was 5.069 E-5 s.

“…Wave propagation modeling is attracting more interest since it provides a way to evaluate the propagation pattern of a wave within a structure like asphalt pavement. Wave propagation modeling has been successfully performed using ANSYS [5] (Ansys Inc., Canonsburg, PA, USA), ABAQUS [6] ABAQUS Inc., Palo Alto, CA, USA), and LS-DYNA (Livermore Software Technology Corporation (LSTC), Livermore, CA, USA) [7]. Finite element method (FEM) was successfully applied in the modeling of three-dimensional propagation of a lead zirconium titanate (PZT) patch-induced Lamb wave through reinforced composites [8] and homogenous plates [9].…”

Non-destructive ultrasonic testing has attained popularity due to its robustness and cost-effectiveness in monitoring the structural health and performance evaluation of pavements, thus replacing traditional methods. This paper presents the application of an explicit finite element method for the modeling of ultrasonic wave propagation through asphalt concrete. Prior to modeling, non-destructive ultrasonic testing was conducted on four different types of asphalt concrete (AC-13, SMA-13, AC-20, and AM-20). Based on acoustic information (wave velocity) obtained in non-destructive testing (NDT) and density, the dynamic moduli of these asphalt concretes were evaluated and used in numerical modeling of ultrasonic wave propagation using the commercial software package ABAQUS. The ultrasonic wave results obtained by numerical modeling were compared with experimental results. This comparison showed a good fit between the finite element (FE) results and the experimental results and confirmed a good FE approach for ultrasonic wave propagation. In addition, the influence of varying dynamic moduli, density, varying location, and crack size/depth on ultrasonic wave propagation was analyzed.

“…erefore, new environment-friendly pavement materials are being studied. To remedy the issue of the hightemperature stability of asphalt pavement, measures, such as the optimization of gradation [1,2], addition of fiber [3], and addition of an antirutting agent [4,5], have been adopted to improve the high-temperature stability of the asphalt mixture. Further, a pavement cooling coating or thermal resistive aggregate can be used to reduce the temperature of asphalt pavements in hot weather [6][7][8].…”

To reduce the temperature of asphalt pavements in summer and improve their high-temperature stability, tourmaline anion powder (TAP) was used as a modifier to prepare modified asphalt, which actively cools the pavement. The effects of different TAP contents on the high- and low-temperature performance of modified asphalt and its pavement cooling performance were studied based on the dynamic shear rheometer, low-temperature bending beam rheometer, and indoor rutting plate temperature difference tests; subsequently, the optimum TAP content was determined. Modified asphalt was used to prepare an active cooling antirutting asphalt mixture, and its pavement cooling performance was verified via outdoor lighting tests. High- and low-temperature dynamic modulus and low-temperature semicircular splitting tests were used to evaluate the high- and low-temperature performance; further, freeze-thaw splitting and immersion Marshall tests were performed to evaluate the water stability of the active cooling antirutting asphalt mixture. The results denote that TAP is useful for improving the rutting factor of asphalt. When the TAP content is 16% of the asphalt material, the maximum cooling value of the surface in laboratory tests becomes 5.9°C. When compared with an ordinary asphalt mixture, the dynamic stability of the active cooling antirutting asphalt mixture at medium and high temperatures increased by 18%–22%. The fracture energy can be increased by 12% at low temperatures. The maximum cooling value of the surfaces in outdoor tests is 7.2°C, and the water stability slightly decreases; however, it still satisfies the specification requirements.
