6. Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide
Sammanfattning : Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. LÄS MER
7. Laboratory Seismic Testing of Asphalt Concrete
Sammanfattning : Nondestructive laboratory seismic testing to characterize the complex modulus and Poisson’s ratio of asphalt concrete is presented in this thesis. These material properties are directly related to pavement quality and the dynamic Young’s modulus is used in thickness design of pavements. LÄS MER
8. Evaluation of Low Temperature Damage in Asphalt Mixtures with Non-Contact Resonance Testing
Sammanfattning : Thetemperature induceddamage in asphalt mixtureshas always been a major distress that requires a substantialconsiderationin the asphalt industry. One of the most important aspects of studying temperature induceddamage is developing a practical test method for evaluation of the material’s resistanceto it. LÄS MER
9. Climate impact on the durability of asphalt concrete
Sammanfattning : Roads are subjected to traffic loads and varying climate conditions that eventually lead to different types of damage. Moisture in asphalt is one of the major causes of premature failure in asphalt pavements. LÄS MER
10. Ice free roads using hydronic heating pavement with low temperature: Thermal properties of asphalt concretes and numerical simulations
Sammanfattning : A traditional method to mitigate the slippery conditions of a road is to spread out salt and sand on the road surface. However, salting causes corrosion on the road infrastructures, damage to surrounding vegetation and salification of fresh water. Hence, there is a need for alternative solutions to mitigate the slippery conditions. LÄS MER
