Sbs Modified Asphalt

The types and contents of styrene-butadiene-styrene (SBS) modifier are two important factors of SBS modified asphalt mixtures. Nowadays, SBS are extensively utilized to modified asphalt in order to improve the performance of the flexible pavement. The objective of this study is to determine a best selection of types and contents of SBS modifier, which can improve high-temperature stability; low-temperature anti-cracking performance and moisture susceptibility of SBS modified asphalt mixture. The mixtures with four types of SBS (Linear A, Linear B, Star A, Star B) and the different contents of each type SBS including Linear SBS of 0%, 3%, 4%, 4.5% and Star SBS of 0%, 3%, 3.5%, 4%, were evaluated for the pavement performance of them under laboratory conditions. Wheel tracking test, beam bending test and freeze-thaw tensile strength test were chosen and carried out to determine high-temperature stability, low-temperature anti-cracking performance and the moisture susceptibility respectively. The laboratory testing results indicate that Star SBS show the more effective effects than Linear SBS to improve the high-temperature stability, low-temperature anti-cracking performance and moisture susceptibility of SBS modified asphalt mixture, and the optimum content of SBS can also play a key role the improvement of the pavement performance.

In order to evaluate the performance of the physical foaming warm-mix recycled asphalt mixture (WRAM), the hot mix plant recycling technology was adopted to develop AC-20 hot-mix recycled asphalt mixture (HRAM) and the WRAM of different reclaimed asphalt pavement (RAP) contents. The high temperature stability, water stability and low temperature crack resistance performance of the reclaimed asphalt pavement were evaluated. The results indicate that the physical foaming WRAM feature better high temperature stability, water stability and low temperature crack resistance compared to those of HRAM. With the increase in RAP contents, the high temperature stability of the physical foaming WRAM and HRAM rises notably but the water stability and low temperature crack resistance performance continues to drop.

Hamburg Wheel Tracking

According to the porous asphalt concrete’s big void structure as well as high temperature and rainy application environment, the author point out that using the conventional evaluation index such as high temperature stability and water stability to evaluate the PAC’s performance seem single, and then put up with estimating the PAC’s pavement performance by means of Hamburg Wheel Tracking under the water-high temperature’s comprehensive action. Studied on the PAC with the same raw materials and different gradations, and compared with the experimental results of AC-13 modified asphalt mixture and SMA-13, the results shows that, Hamburg Wheel Tracking test not only considered the water-high temperature’s comprehensive action on mixture, but also considered the mixture’s performance decay under long-term loading. Hamburg Wheel Tracking test can evaluate the PAC’s performance more practically, the PAC which materials and graduations reasonably designed have good performance, and its Hamburg Wheel Tracking final deformation is only 3.89mm, it can satisfy the demand from the high temperature and rainy environment. As well, the test results also comes to the conclusions that under the same materials and the same air voids, the PAC with coarse framework structure own better water stability and water-high temperature stability.
