Special Issue Information

Dear Colleagues,

This Special Issue is centered on the interdisciplinary domain of sustainable operation and maintenance for intelligent transportation systems. Its overarching goal is to construct a comprehensive technological framework spanning from perception to decision-making, construction, and operation. In the realm of intelligent perception, this study leverages the integration of multiple traffic information sources and delves into the analysis of vehicle–road interaction mechanisms. By doing so, it aims to elucidate the dynamic load characteristics of vehicles and the intricate interactions between roads and vehicles. Such efforts lay a solid theoretical groundwork for evaluating the status of infrastructure. Regarding digital technology applications, a Building Information Modeling (BIM)-based digital operation and maintenance platform for intelligent transportation infrastructure has been developed. This platform, in combination with long-term performance prediction models and material analysis, enables the visual management of data throughout the entire lifecycle of transportation facilities. The proposed integrated design approach for the maintenance system represents an optimal solution for minimizing life cycle costs. In the area of intelligent construction technology, this research emphasizes the optimization of asphalt pavement material mixtures and the precise control of construction process parameters. Through the implementation of digital twin technology, real-time monitoring and adjustment of construction quality can be achieved. Moreover, this study introduces an innovative deep learning method to analyze damages under various conditions and environmental factors. This approach provides intelligent decision support for preventive maintenance strategies. By integrating cutting-edge information technologies, including intelligent perception, digital twins, and artificial intelligence, with traditional civil engineering practices, this research system propels the development of intelligent infrastructure towards the realm of “self-adaptive perception, self-decision-making, and self-optimization”.

Structural cracks are internal distresses that cannot be observed from pavement surfaces. However, the existing evaluation methods for asphalt pavement structures lack the consideration of these cracks, which are crucial for accurate pavement assessment and effective maintenance planning. This study develops a novel framework combining a three-dimensional (3D) ground penetrating radar (GPR) and finite element modeling (FEM) to evaluate the severity of structural cracks. First, the size and depth development of structural cracks on a four-layer asphalt pavement were determined using the 3D GPR. Then, the range of influence of the structural crack on structural bearing capacity was analyzed based on 3D FEM simulation model. Structural cracks have a distance-dependent diminishing influence on the deflection in the horizontal direction, with the most pronounced effects within a 20-cm width zone surrounding the cracks. Finally, two indices have been proposed: the pavement structural crack index (PSCI) to assess the depth of crack damage and the structural crack reflection ratio (SCRR) to evaluate surface reflection. Besides, PSCI and SCRR are used to classify the severities of structural cracks: none, low, and high. The threshold between none/low damage is a structural crack damage rate of 0.19%, and the threshold between low/high damage is 0.663%. An experiment on a 132-km expressway indicated that the proposed method achieved 94.4% accuracy via coring. The results also demonstrate the strong correlation between PSCI and pavement deflection (R2 = 0.92), supporting performance-based maintenance strategies. The results also demonstrate the correlation between structural and surface cracks, with 65.8% of the cracked sections having both structural and surface cracks. Full article

The design of asphalt mixture has, for a long time, been an empirical and proof process, causing the mismatch between material design and pavement structure design. To enhance the rationality of asphalt pavement design, this study seeks a path to bridge the gap between asphalt mixture modulus and structural behavior. Firstly, pavement models with different base rigidities, including cement concrete base, cement-treated granular base, and granular base, were constructed to calculate the pavement responses under different dynamic modulus master curve parameters. The influence of master curve parameters on critical pavement responses was identified by the response surface method (RSM). Furthermore, a Whale Optimization Algorithm–Back Propagation (WOA-BP) artificial-neural-network-based pavement response prediction model was established. Then, a database mapping over 100 thousand pavement responses and dynamic modulus master curve parameters was built for determining the dynamic modulus master curve parameters by optimizing the pavement responses. The results show that the impacts of dynamic modulus master curve parameters on critical pavement responses depend on pavement structures. In general, parameter δ has the greatest impact, followed by α, while the effects of β and γ are relatively small. The Artificial Neural Network (ANN) performance prediction model, optimized by the WOA algorithm, has a high accuracy. The methodology for determining the dynamic modulus master curve parameter based on the critical response of pavement was successfully implemented. The findings can bridge the gap between material design and structure design of asphalt pavement and provide a basis for more accurate and reasonable asphalt pavement design. Full article
