Phd Student In Improved Long-Term Asphalt Rutting Prediction And Characterization, At KTH, Sweden
Project Description
In this project you’ll be investigating the applicability of a recently proposed test in the USA for Swedish
materials, Swedish weather conditions and heavier loading conditions. Since the test is currently lacking a fundamental explanation of why it seems to work so well, you will evaluate the test, using X-ray tomography for monitoring the damage development as a function of mixture properties and test conditions and coupling that to simulations, utilizing a calibrated mechanics based design tool currently under development at KTH. The outcome of this project could be a fast new characterization test with a scientific basis that can be used in Sweden to support the performance-based contracts and to investigate the effect of heavy loads. Additionally, insight regarding the development of rutting damage in Swedish conditions will be generated in the project.The following results will be expected from your research:- A validated test protocol for asphalt rutting performance under Swedish conditions;- A detailed evaluation of the rutting potential of selected Swedish mixtures under various temperature and loading conditions;- Detailed scientific analyses of damage development inside the asphalt mixtures, as a function of mix design, temperature, moisture and load levels:- A coupling to the calibrated mechanics based framework developed at KTH to simulate the long term performance, based on the material characterization.
Eligibility and Assessment Criteria
The potential candidate must have a master’s degree in Mechanical Engineering, Civil Engineering or Experimental Physics. Basic knowledge in computational modeling and experimental fatigue tests is required and a specialization in asphalt, concrete, granular materials or other construction materials is of added value.The candidate should be highly motivated for doing scientific research and should have well developed analytical and problem solving skills as well as an interest and curiosity for different types of computational and experimental methods. Hands-on experience from manufacturing with construction materials is an asset.
