“…On the other hand Zhang et al [10] conducted a comparative evaluation of the FN, DM and RLPD tests, found that the FN Index, in contrast to the classical FN (cycles) parameter, exhibited a better correlation with results of both the DM and RLPD tests. Xu et al [8] carried out the partial triaxial test (PTT), and stated that a strong correlation was found between the strain slope value at the second stage in the PTT and the total rut depth in the WTT. In the work of Radhakrishnan et al [7], a strong correlation was observed between the time lag in the resilient modulus test and the rut depth measured in the wheel tracking test.…”

The paper presents the dependence of ITS results at the elevated temperature (40°C) on rutting parameters, i.e.proportional rut depth (PRDAIR) and wheel tracking speed (WTSAIR), obtained at the temperature of 60°C. The asphalt mixture samples were prepared in the gyratory compactor, but ITS tests were conducted with typicalMarshall press, at a loading rate of 50 mm/min. Correlation analyses show a strong relationships between ITS results and rutting parameters, whereby the correlation coefficients obtained are higher for the PRDAIR parameter (r = -0.88) than WTSAIR (r = -0.81). Using the obtained regression functions, the prediction limits as well as confidence limits were calculated, which allowed to develop criteria for assessing resistance to rutting on the basis of ITS test, and taking into account the technical requirements in Poland.Keywords: asphalt concrete (AC), indirect tensile strength (ITS), proportional rut depth (PRD), wheel tracking speed (WTS), permanent deformation of the asphalt pavement

“…Development of permanent deformations reduces the service life of asphalt pavements. Furthermore, this distress could decrease the level of safety in road transportation networks and causes road maintenance agencies to incur considerable costs [4][5][6][7][8]. Factors affecting asphalt mixture rutting include materials' physical characteristics, bitumen properties, and pavement volumetric features.…”

“…In another approach, microcapsules containing rejuvenator are used to improve the cracking performance of the asphalt pavement by increasing its self-healing properties [12]. Modifying bitumen with additives is usually applied to change phase combination and to improve the mechanical properties of the asphalt mixture [5,13]. On the contrary, nanoparticles are among the known additives used for the modification of bitumen features [14][15][16].…”

Rutting is one of the most common distresses in flexible pavements and can affect vehicle controlling features. Although asphalt binder constitutes a small percentage of the asphalt mixture, its properties play a crucial role in pavement performance and its rutting resistance. One way of improving binder properties and rutting resistance is to use additives. In this research, nanoclay and SBR polymer have been simultaneously used to modify 60–70 penetration binder to study rutting resistance of binder and asphalt mixture. To this end, the storage stability, rotational viscosity, DSR, and RCR tests on binder and marshal stability were performed, and dynamic creep and wheel track tests on asphalt mix were performed to assess rutting performance. The test and statistical analysis results indicated that nanoclay has considerably positive impact on rutting and elastic deformation of neat and SBR-modified asphalt binder and mixture.

“…Several studies have addressed the use of fibers to improve the HMAs performance: a few of them focused on the specific performance related to environmental, water and temperature effects [15,16], while other experimentations were carried out to highlight HMAs' mechanical performance, e.g. stiffness [17], fatigue [18] and rutting [19]. Another line of research has been devoted to investigate the whole performance of fiber-reinforced HMAs [20,21], their mix-design [22], or their performance related to the effects of fibers during compaction [23].…”

The experimental investigation herein described is aimed at understanding the effects of cellulose-based fibers on the mechanical properties of bituminous mastics for paving applications. Three bitumen (two of which modified with SBS polymers), a calcareous filler and four different types of fiber with varying content were used to prepare the investigated mastics. The filler to bitumen ratio was maintained constant. The laboratory investigations were focused on empirical tests (Needle Penetration andRing and Ball -R&B -Temperature) and dynamic-mechanical tests, the latter performed in a wide range of temperatures. Results suggest that fibers improve the M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 2 behavior of mastics for hot mix asphalts, particularly with respect to the prevention of rutting phenomena at high service temperatures.
