Performance Study on Asphalt Mortar with Dynamical Shear Rheometer
Advanced Materials Research, 2014A series of asphalt mortars were prepared and tested by dynamic shear rheometer and other common evaluation methods aiming at investigating the physical performance of asphalt mortars. The final analysis shows that the changes of strength modulus and viscoelastic property rely on the composition differences in asphalt mortar, and modified asphalt and ...

Research of Bituminous MortarFatigue Test Method Based on Dynamic Shear Rheometer
Journal of Testing and Evaluation, 2012Abstract This paper presents a new test method that allows fatigue characterization on bituminous mortar by means of dynamic shear rheometer (DSR). The studied mortar is composed of bitumen, filler and fine sand at a mass ratio of 0.34:0.30:0.36.

Identification of Concrete Incompatibilities using Dynamic Shear Rheometer (DSR)
Proceedings of the International Conference on Concrete PavementsIn concrete, the chemical interactions between chemical admixtures and portland cement is complicated and unpredictable. Occasionally these interactions may cause a serious set retardation or excessively fast stiffening. The objective of this study was to develop a reliable test method to predict potential concrete incompatibilities through the direct ...

Understanding mechanisms leading to asphalt binder fatigue in the dynamic shear rheometer
Road Materials and Pavement Design, 2013Asphalt binder fatigue resistance is important in determining overall pavement fatigue performance. One procedure commonly used to characterise asphalt binder fatigue resistance is the time sweep test, which consists of repeated cyclic loading in the dynamic shear rheometer (DSR).

Fatigue and healing characteristics of bitumens studied using dynamic shear rheometer
Sixth International RILEM Symposium on Performance Testing and Evaluation of Bituminous Materials, 2003This paper characterizes the fatigue and healing behavior of bitumen using a dynamic shear rheometer (DSR). Different types of bitumen, before and after aging, were investigated in strain- and stress-controlled modes. Procedures of storage recuperation and intermittent loading were used to determine the effect of healing on bitumen fatigue. The results

Modelling of cohesion and adhesion damage of seal based on dynamic shear rheometer testing
International Journal of Pavement Engineering, 2016AbstractMost current seal designs are based on the volumetric properties of materials and voids. In order to improve seal design, the possibility of introducing mechanistic principles into seal design was investigated. Introducing mechanistic concepts into seal design means that principles such as elasticity and viscoelasticity could be used in terms ...
