The Department of Civil Engineering awards a master’s degree in pavement rutting analysis
The Department of Civil Engineering at the University of Technology awarded a master’s degree to the student (Noor Sadeq Hatem) for her research tagged:
Analysis of Asphalt Concrete Pavement
Rutting Using Finite Element Method"
"Analysis of grooves in asphalt pavement using the finite element method" on 12/7/2021
The research included that permanent deformation (rutting) is one of the most important and widespread types of damage that occurs in flexible sidewalks, especially in countries where temperatures are high during the summer. In this study, a combined effect between temperature and load applied to the asphalt layer was worked out in the finite element analysis using the counter program. The asphalt layer is a layer with a flexible material, while the base layer and the bottom layer are flexible plastic materials that follow the Mohr Coulomb model.
The geogrid was used as a reinforcing material and the type of geogrid was SS2. The geological layer used was 6 mm thick and was placed between the asphalt layer and the base layer to reduce cracks that occur on the road as a result of traffic loads and changing environmental conditions.
A special result was extracted from the statistical analysis through the SPSS program and equations were obtained to predict the vertical stress in the surface layer as a function of layer thickness, load, velocity, temperature and number of cycles for paving layers without geogrids.
