“…This causes a significant stress difference along the pavement edge. In addition, the loads that are also applied to rigid pavements, the stresses that occur will concentrate in certain areas that experience higher loads [10]. Under edge loading, stresses will concentrate along the pavement edges and spread into the pavement structure.…”

This study presents the results of research on the stress behavior of rigid pavement concrete slabs by varying CBR subgrade values. It aims to know the effect of changing the rigid pavement strss. Data used in this study are geometric data and material properties of the pavement structure. The load vehicle considered is National Road class standard. Rigid pavement is very sensitive with un-uniformity of underlaying supposrt. In this research, the effect of un-uniform support of subgrade was modeled numerically using Abaqus software. The friction coefficient of each layer was also considered in the model. Model simulation of existing rigid pavement calculated 13 variations of CBR values. Result shown that there is a stress increment by 26.27% in the longitudinal direction of the rigid pavement between models with uniform variations of CBR and models with non-uniform variations of CBR. This result show the sensitivity of rigid pavement to un-uniformity of subgrade.

“…In terms of materials, in order to enhance the pavement performance and make the materials more ecologically and energy-efficient, and ultimately to achieve the goal of a "carbon neutral" vision [6], the application of rubberized asphalt (RA) and its mixtures have been a prominent topic of study, with numerous researchers conducting in-depth investigations on it [7][8][9]. Rubberized asphalt is widely used in stress-absorbing layers and rutting-resistant sections of asphalt pavements due to its exemplary environmental performance, rutting resistance, and durability, thus prolonging the pavement's service life [10].…”

This study addressed the complex problems of selecting a constitutive model to objectively characterize asphalt mixtures and accurately determine their viscoelastic properties, which are influenced by numerous variables. Inaccuracies in model or parameter determination can result in significant discrepancies between the calculated and measured results of the pavement’s structural dynamic response. To address this, the research utilized the physical engineering principles of asphalt pavement structure to perform dynamic modulus tests on three types of high-content rubberized asphalt mixtures (HCRAM) within the surface layer. The research aimed to investigate the influencing factors of the dynamic modulus and establish a comprehensive master curve. This study also critically evaluated the capabilities of three viscoelastic models—the three-parameter solid model, the classical Maxwell model, and the classical Kelvin model—in depicting the dynamic modulus of HCRAM. The findings indicated a negative correlation between the dynamic modulus of the asphalt mixture and temperature, while a positive association exists between the loading frequency and temperature, with the impact of the loading frequency diminishing as the temperature increases. Notably, the three-parameter solid model was identified as the most accurate in describing the viscoelastic properties of the HCRAM. Furthermore, the dynamic response calculations revealed that most indexes in the surface layer’s dynamic response are highest when evaluated using the three-parameter viscoelastic model, underscoring its potential to enhance the pavement performance’s predictive accuracy. This research provides valuable insights into optimizing the material performance and guiding the pavement design and maintenance strategies.
