Relationships Between the Fatigue Properties of Asphalt
Although R has not been widely used in developing fatigue models for asphalt concrete mixes, there should be a relationship between the binder R-value and asphalt mixture fatigue performance because of its close relationship to PI and the use of PI in the Shell fatigue equations. Figure 3.
Evaluation of Rut Resistance of Polymer-Modified Asphalt
The rutting is a significant damage mechanism showing longitudinal furrows along with both wheel paths on asphalt pavement surface. To prevent the rutting under heavy traffic condition, polymer-modified asphalt (PMA) concretes were introduced in asphalt pavement industry. To measure rut resistance of asphalt concretes, the asphalt pavement analyzer (APA) and the deformation strength, SD, were

Evaluation of internal resistance in hot-mix asphalt (HMA
Accurate quantification of aggregate properties is essential for understanding their influence on hot-mix asphalt (HMA) concrete and for selecting aggregates to produce high-quality paving mixture. The objectives of this study are to develop a method to measure internal resistance in HMA mixtures and to evaluate the effect of different gradations on the rutting of mixes.
