1. 1. Evaluation of HMA fracture mechanics-based thermal cracking model.

   Master-uppsats, KTH/Transportvetenskap

   Författare :Sen Lin; [2011]
   Nyckelord :Hot Mix Asphalt; Low temperature cracking; HMA fracture mechanics; Thermal cracking model; SuperPave IDT; Thermal Stress Restrained Specimen Test;

   Sammanfattning : Low temperature cracking is an important form of asphalt pavement deterioration in cold regions. The cracks develop when thermally induced stresses exceed the fracture resistance of the asphalt pavement. LÄS MER

3. 2. Implementation of the SuperPave IDT analysis procedure

   Master-uppsats, KTH/Väg- och banteknik

   Författare :Guangli Du; [2010]
   Nyckelord :SuperPave indirect tensile test; resilient modulus; creep compliance; fracture energy; dissipated creep strain energy;

   Sammanfattning : Cracking is one of the most severe distress modes of asphaltpavements. Thus characterising the fracture resistance properties of asphaltmixtures is the key issue for improving the performance relatedmixture design. LÄS MER

4. 3. Towards a Uniform Fracture Mechanics-Based Framework for Flexible Pavement Design

   Master-uppsats, KTH/Väg- och banteknik

   Författare :Prabir Das; [2009]
   Nyckelord :Crack growth; Low temperature cracking; Fracture mechanics; Dissipated creep strain energy; Asphalt pavements; Energy Ratio;

   Sammanfattning : Cracking is an important potential failure mechanism for pavement structures. By combining a strain energy-based fracture criterion with conventional fracture mechanics based on the Energy Ratio (ER) concept, crack growth in asphalt can be investigated, and a low temperature Thermal Cracking model (TCMODEL) can be introduced.
