Analysis of the Coupling Effect of Thermal and Traffic Loads on Cement Concrete Pavement with Voids Repaired with Polymer Grout

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Under the repeated action of traffic and thermal loads, a cement concrete pavement slab may partially lose contact with its base course, and voids may develop underneath the slab. Such distress will greatly impact the pavement performance. To fill the voids and restore the base support to the slab, the technology of polymer grouting has been ...

Study of the Effect of Grouting Material Strength on Semiflexible Pavement Material

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
In this study, cement mortars with different strengths are poured into the large void matrix asphalt macadam material as a semiflexible pavement (SFP) material and the experimental research is carried out. The current research on SFP is mainly focused on the performance of grouting materials and the influence of grouting matrix materials on the overall

Mechanical Analysis of Preventing Reflection Cracks Based on Stress Absorbing Layer

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
After asphalt concrete overlay, the reflection crack in the old pavement remains a great challenge. In order to overcome this problem, here, we report the effect of stress absorbing layer on the reflection crack. First, the concrete measures to prevent and reduce reflection cracks at home and abroad are analyzed.

Multiple Reflective Cracks in Semirigid Base Asphalt Pavement under Traffic Load Using XFEM

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
This paper built a three‐dimensional layered structure model of semirigid base asphalt pavement with single and double transverse reflective cracks based on the Extended Finite Element Method and fatigue fracture theory. The effects of the number of cracks, crack spacing, and crack length on the stress intensity factors (KI, KII, and Keff) under moving

Research on Fatigue Model of Semi‐Rigid Base Asphalt Pavement before and after Polymer Grouting

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
To improve the service life of a semirigid base asphalt pavement and prolong its service cycle, it is imperative to conduct long‐term performance research before and after pavement disease repair. This study proposes a fatigue damage model for pavement and polymer materials and uses the finite element method to establish a three‐dimensional numerical ...

Numerical Analysis of the Soil Deformation Caused by Tunneling under Vehicle Loads in the Coastal Reclamation Area

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
Prediction of tunneling induced soil deformation is an important issue in the design of tunnels constructed in the densely populated urban areas. In this paper, commercial FEM software 3D ABAQUS is adopted to simulate the behavior of soil caused by tunneling under vehicle loads in the coastal reclamation area. A field case study was also carried out to
