  1. 1. The effect of filler type and shape on HMA energy dissipation performance.

    University essay from KTH/Väg- och banteknik

    Author : Yohannes Gebremeskel Kiflat; [2013]
    Keywords : Hot mix asphalt; mastic; fillers; compaction energy index; superpave;

    Abstract : Hot mix asphalt pavements require adequate compaction to achieve the required density to resist rutting. The amount of energy required to achieve the optimum degree of compaction depends on the type of gradation, bitumen content, filler type and shape, type of compaction equipment etc. READ MORE

  3. 2. Evaluation of HMA fracture mechanics-based thermal cracking model.

    University essay from KTH/Transportvetenskap

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

    Abstract : 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. READ MORE

  4. 3. Implementation of the SuperPave IDT analysis procedure

    University essay from KTH/Väg- och banteknik

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Väg- och banteknik

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

    Abstract : 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.
