Analysis of Hot Mix Asphalt (HMA) Linear Viscoelastic and Bimodular Properties Using Uniaxial Compression and Indirect Tension (IDT) Tests
… to predict rutting and fatigue cracking, and the Indirect Tension (IDT) creep compliance test to predict low-temperature thermal cracking. The creep compliance and dynamic modulus are measured responses (viscoelastic functions) of viscoelastic materials under transient and cyclic loading, …

Resistance of Carbon Fibre Reinforced Composites to Quasi-static and Ballistic Perforation
… the two most prominent failure modes were indirect tension and shear plugging. To characterise the indirect tension mechanism, CFRP cross-ply coupons with various matrix shear strengths were subjected to uniaxial out-of-plane compression between lubricated platens, while CFRP cross-ply …

Investigation of cracking resistance of recycled Superpave mixtures
… RAS. Illinois semicircular bending and Florida indirect tension tests were performed to assess mixture cracking and fracture properties. Results showed that mixtures containing 10% RAP and 5% RAS have relatively low fracture energy, creep compliance, energy ratio, and flexibility index but high …

Exploring the Black Space of Compressive and Shear Modulus
… Three tests were performed: Uniaxial |E*|, Indirect Tension (IDT |E*|), and Torsion Bar |G*|. Traditional Master Curves and Black Space diagrams were plotted to have a comparison between all materials. The results show that Black Space diagram plotted with the Torsion Bar |G*| configuration …

Comparison of Creep Compliance Master Curve Models for Hot Mix Asphalt
… used in this thesis; uniaxial compressive and indirect tension (IDT) creep compliance. The tests were conducted at five temperatures (-15, 5, 20, 30, and 40°C) with a static loading for 1000-sec to characterize two typical HMA mixes used in Virginia, a base and a surface mix. Creep compliance …

Quantification of the Role of The Effective Binder in the Performance of RAP – WMA Mixtures
… was used for cracking evaluation, while the Indirect Tension Test at High Temperatures (IDT-HT) was used for rutting evaluation. Further, the study included rheological characterization of extracted binder from the mixtures to investigate the role of the effective binder on cracking …

Laboratory Comparison of Full Depth Reclamation Stabilization Techniques Using Arkansas Field Materials
… stabilizer contents were determined using the indirect tensile strength test for asphalt emulsion and asphalt foam stabilization and the unconfined compressive strength test was used for the cement stabilized samples. Once the mix designs were validated and optimal contents were determined, …

Micromechanics of ultra-high molecular weight polyethylene fibre composites
… that beams with low shear strengths fail by the indirect tension mode at high impact velocities while beams with high shear strengths fail by the bending mode at significantly lower impact velocities. The study thus provides a mechanistic understanding of the experimental observations that high …

Evaluation of selected airport pavements in New Mexico
… for parameters such as resilient modulus (MR), indirect tensile strength (ITS), void ratio, asphalt content, and aggregate gradation. These parameters are used to determine the structural strength of a pavement in this study. Based on the PCI value, 5 out of 19 runway pavements are found to be …

Nano-scale evaluation of moisture damage in asphalt
… for examining such correlations. Macro-scale indirect tension tests are conducted on wet and dry asphalt concrete samples. A good correlation exists between the macro-scale indirect tensile strength ratio, and nano-scale adhesion ratio of wet and dry samples.'
