C9 Petroleum Resin and Polyethylene-Based High-Viscosity . . . - MDPI From the rheological test (two parallel specimens), complex modulus and phase angle evaluation indicators were obtained to characterize the rheological properties of the high-viscosity modified asphalt binders
Evaluation of the rheological properties and molecular distributions of . . . Two oils with their molecules that are mainly distributed in the medium molecular size (MMS) range, which compensate the loss of the MMS molecules of the base binder due to aging, show the good effectiveness in restoring not only the complex modulus but also the phase angle of the aged asphalt
Complex shear modulus and phase angle of crumb rubber modified binders The binders were tested with a Dynamic Shear Rheometer (DSR) The standard used for this test is EN 14770:2012 (Determination of complex shear modulus and phase angle - Dynamic Shear Rheometer (DSR)) [23] x modulus G*, consequently, the stiffness of the binders is increased The phase angle values decrea ed, as the addition of rubber increa
Asphalt Binder PG Tests - FHWA West Virginia Division The complex shear modulus and phase angle together are used to characterize the binder at high and intermediate temperatures in order to determine the performance grade
Prediction of Rheological Properties of Bio-asphalt Binders Through . . . The interaction effects of CPO at 0%, 5%, 10% and 15% by weight of the base asphalt binder and test temperatures of 40 °C– 76 °C as independent variables on the complex modulus and phase angle were evaluated Results show that CPO content and test temperature have significant effects on the complex modulus and phase angle of bio-asphalt
CE 473 Pavement Design Christensen-Anderson (CA) model (1992) to predict the change in binder complex modulus and phase angle Pavement distresses are often related to cracking The effect of oxidative aging on cracking potential needs to be addressed Few studies have worked on how aging affects the fracture properties which are directly related to cracking
Determining the Rheological Properties of Asphalt Binder Using a . . . The complex shear modulus is an indicator of the stiffness or resistance of asphalt binder to deformation under load The complex shear modulus and the phase angle define the resistance to shear deformation of the asphalt binder in the linear viscoelastic region
