The primary...

...Roozbeh Zarroodi; Koorosh Naderi; Mehdi Moazami Goodarzi; Hossein Nazari; Fereidoon Moghadas Nejad One method for reducing the rutting failure of asphalt pavements is to modify the asphalt binder with polyethylene. However, the instability and phase separation between components has always been...

... (SBS). Different percentages of nanoclay were added to the original binder (1, 2, 3 and 4 % by the weight of the binder). The fatigue and rutting behavior of binders were evaluated through linear amplitude sweep and multiple stress creep recovery (MSCR) tests. To investigate the performance of mixtures...

...Samira Sadat Kashfi; Javad Tanzadeh; Fatemeh Ramzanniya Gilani Slurry seals are a hard wearing surface for pavement preservation. The main purpose of this study is to investigate the effects of nanomaterials and styrene butadiene rubber (SBR) latex on fatigue and rutting performance, wet cohesion...

...Shuyin Wu; Jun Yang; Ruochong Yang; Jipeng Zhu; Song Liu As one of the major diseases of asphalt pavement, rutting has become an important research topic. The current treatment method of rutting generally requires the milling of asphalt layers and construction of a new overlay, which is time...

... that the Superpave high-temperature PG and the rutting factor did not reduce by an increase in the WMA additive content. However, the continuous low-temperature PG of the asphalt binder decreased with an increase in the amount of WMA additive. Furthermore, it was found that the fatigue resistance increased after...

... (HMA-RAP) has an improved resistance to permanent deformation (rutting) and decreased resistance to the fatigue cracking. This is due to the fact that asphalt binder contained in the RAP has been oxidized over the years and is typically stiffer than virgin asphalt binder. However, during the production...

...Chao Wang; Yang Wang; Yangzhou Chen; Aboelkasim Diab; Zhanping You The objective of this article is to investigate the effects of temperature on rutting and fatigue cracking resistance of asphalt binders based on the time-temperature superposition principle (TTSP). In this study, the TTSP approach...

... on the contribution of heavy traffic loading to rutting/permanent deformation that occurred on the surface asphalt layer along the Korogwe-Mombo road section. To improve the accurate determination of traffic loading, traffic studies should ideally be conducted over a long period (typically over 1 year). However...

Increased rut resistance and higher fatigue lives were observed for higher RAR contents. Statistical analyses revealed insignificant changes in fracture energy among the different mixtures, and all...

The performance of the Qingchuan rock asphalt–modified asphalt was analyzed based on modified asphalt index tests, the dynamic shear rheometer test and the bending beam rheometer test. Performance verification of the Qingchuan rock asphalt–modified asphalt was conducted using the rutting...

... to have the better performance in tensile strength and rutting resistance compared to unaged PACs, but the aging has a detrimental influence on the raveling resistance and moisture susceptibility. The 4-day long-term aging procedure led to a considerable reduction in the tensile-strength ratio for PAC...

...Feng Hong; Darhao Chen Permanent deformation in materials can lead to rutting on an asphalt pavement. Rutting poses potential hazard to vehicles running on the pavement because of hydroplaning during wet weather conditions. To mitigate or remedy rutting, it is of critical importance to identify...
