“…The mechanical response of asphalt pavement structure is greatly affected by different interlayer bonding conditions [7][8].

Based on the typical full depth asphalt pavement structure in Shandong Province, the mechanical response of full depth asphalt pavement structure is analyzed by the elastic layer theory to optimize the combination of full depth high modulus asphalt pavement structure. The reasonable layer of high modulus asphalt mixture was determined. And the influence of interlayer bonding state and temperature on the performance of full depth high modulus asphalt pavement were analyzed. The fatigue life of full depth high modulus asphalt pavement, full depth ordinary asphalt pavement and semi-rigid base asphalt pavement was compared. The results show that the use of high modulus asphalt concrete can significantly improve the structural performance of full depth asphalt pavement. The application of high modulus asphalt mixture in middle and base layer is the most reasonable. The interlayer bonding condition and temperature have significant influence on the tensile strain of asphalt pavement structure. The fatigue life of asphalt pavement under high temperature condition is lower, which should be taken into consideration in the design of pavement structure. The calculated fatigue life of full depth high modulus asphalt pavement is obviously higher than that of full depth ordinary asphalt pavement and semi-rigid base asphalt pavement.

“…Pavement responses computation in the BISAR program generates complete calculation results in a pavement structure due to various loading categories and predictions of pavement structures. To further expand on the program's accuracy, a comparison of BISAR and EverStressFE was carried out to investigate the interlayer bounding problem of the asphalt pavement system [62]. The output of the results indicated that both programs' discrepancy in analyzing the mechanical response of the asphalt pavement interlayer problem does not provide any significant difference, and further concluded that the professional tools are excellently useful.…”

Transport and international agencies invest millions of dollars on road projects to support countries develop their infrastructure; therefore, it is important to ensure longer service life and value for money. The primary function of the pavement structure is to keep distresses, including fatigue cracking and permanent deformation, to an acceptable limit so that the pavement can withstand applied vehicle load and repetitions during the service duration. Furthermore, the layered structure of the pavement is intended to ensure that the vehicle contact pressure is distributed in such a way that critical responses at the bottom layer of the pavement are low enough to avoid severe damage. Two typical procedures associated with roadway pavement design are empirical-based and structural analysis methods. However, the empirical-based methods have significant shortcomings, as predicting the mode and extent of pavement performance becomes a major challenge. Alternatively, the structural analysis methods have advanced extensively with computers since they consider crucial factors such as traffic loads, material characteristics and environmental conditions. The imputation of these parameters into the computer algorithm contributes to a better understanding of the mechanical performance of constituent pavement material responses. The predicted responses enable highway engineers to select appropriate pavement compositions that will deteriorate at a satisfactory level during the time of service. The most common structural analysis approaches are analytical modelling and numerical simulation. On the other hand, differences in analysis results generation using these approaches have been a notable concern. This review article presents a synopsis of typical pavement design methods and the problem connected with them; structural approaches to identify factors influencing their accuracy. Furthermore, computer algorithms use due to their usefulness, and the assumptions of layered theories employed in pavement structural design are discussed to uncover potential drawbacks for future upgrades.

“…These structures often face challenges related to interlayer bonding due to factors like construction techniques and environmental conditions. Insufficient bonding between the semi-rigid base and asphalt surface leads to an increased occurrence of reflective cracks in asphalt pavements, ultimately diminishing their service life [6][7][8]. Previous studies have shown that weakened interlayer bonding results in heightened tensile strain in the upper part of the interlayer, leading to a substantial reduction in the fatigue life of the asphalt pavement, up to 75.6% [9][10][11].…”

To evaluate the applicability of three-dimensional ground-penetrating radar (GPR) in assessing interlayer bonding within asphalt pavements featuring semi-rigid base layers, we conducted an analysis of the GPR detection mechanism. Employing forward simulation, various medium models were created to analyze electromagnetic wave transmission in air, water, and sand. GPR testing was applied to four distinct pavement structures, utilizing amplitude intensity levels and image processing techniques to assess asphalt pavement interlayer bonding. The results were validated by comparing them with core samples. The findings revealed a significant influence of medium uniformity on electromagnetic wave transmission processes. Non-uniform media models generate a large number of clutter waves, which refers to amplitudes and phases that have no predictable regularity in time and space i.e., they show irregular ups and downs and fluctuations. It is similar to the clutter that occurs during actual detection. Poorly bonded areas exhibited clearer hyperbolic ripples, primarily attributed to significant differences in the dielectric constants of filling materials. Amplitude strength effectively evaluated bonding across different asphalt pavement configurations and lanes, typically following a normal distribution. Enhanced interlayer contact correlated with smaller amplitudes, while weaker bonding led to larger amplitudes. The amplitude distribution in the center of lanes differed significantly from wheel track areas, indicating better interlayer bonding conditions in the center lanes compared to the wheel track belt. Moreover, radar plan views demonstrated considerable variation across different interlayer contact conditions. The image processing method proved effective in evaluating the interlayer contact condition of various pavement structures across full cross-sections.
