2021-3-3  Objectives: The proposed research will develop an innovative method to use Inverse Approach to characterize three fundamental properties (the elastic modulus, the yielding strength, and an internal loading transfer parameter to represent mastics-aggregate skeleton interaction). These three parameters represent the rutting resistances of asphalt so that different scales of simulative tests and

Characterizing the three-stage rutting behavior of

2017-6-1  Fig. 11 shows that the rutting development rate of asphalt pavement are similar to the three-stage permanent deformation characteristics of asphalt mixture, that is the rutting depth firstly fast increases with the loading repetitions with a slowdown rate, then maybe steadily increases with a constant rate decrease, and finally sharply increases with an accelerated rate. The faster the rutting development is, the earlier the pavement

Characterizing Stress–Strain Relationships of Asphalt ...

Due to its lower binder content and lower-quality granular material, asphalt treated base (ATB) exhibits a stress–strain relationship unlike either regular granular material or hot mix asphalt. Stress−strain relationship is the primary fundamental material property used for mechanistic-based pavement structural analysis and design.

Correlating the asphalt-binder high-temperature

2020-11-30  In their study, three methodological approaches were used for characterizing the rutting performance of the asphalt-binders, namely: (a) the G*/Sin (δ) rutting parameter, (b) the linear viscoelastic elastic models proposed by Anderson et al. and Shenoy , and (c) the non-recoverable creep compliance parameter (Jnr), determined using the MSCR test. RLPD tests were subsequently performed on the laboratory prepared HMA specimens manufactured using the same four asphalt-binders.

2021-6-1  1. Introduction. Rutting is one of the major distresses generated in the asphalt pavement, which is a permanent deformation induced by the horizontal and lateral displacement of the asphalt mixture (Rahi et al., 2015).As a viscoelastic material, the deformation of asphalt mixture is generally grouped into two parts, namely the elastic deformation and the viscous deformation.
