“…Based on our previous research [ 19 , 21 ], Pal was treated with 1 mol/L HCl solution at 60 °C for 1 h to remove some large particles and cationics outside the raw material, then washed to neutral and dried. The treated Pal and γ-aminopropyltriethoxysilane (APTES) were dispersed in xylene solution, and the condensation reflux method was used for magnetic stirring for 10 h, then washed several times with the filtrate, dried and crushed to obtain A-Pal to enhance compatibility with the asphalt matrix.…”

“…Sun et al [ 15 ] applied Pal to epoxy asphalt, and found that it has a good effect on tensile and adhesive properties. Jin et al [ 19 ] applied organic-Pal to asphalt, and found that the aging resistance of asphalt was greatly improved. At present, the effect of organic-Pal on styrene-butadiene-styrene (SBS)-modified asphalt is rarely studied.…”

With the rapid development of economic construction, styrene-butadiene-styrene (SBS)-modified asphalt is being more and more widely used in highway engineering, but there are still many deficiencies in the process of its use. In order to further improve its performance for use, nano-organic palygorskite (A-Pal) and star-shaped SBS were compounded to obtain modified asphalt in this study. The high-temperature stability of SBS-modified asphalt was enhanced after incorporation with A-Pal for the high-temperature stability test by a dynamic shear rheometer. The A-Pal should improve the surface free energy and adhesion of SBS-modified asphalt by the water stability test analysis. The aging test shows that A-Pal can reduce the thermal oxygen decomposition of SBS and improve the anti-aging performance and the fatigue resistance of SBS-modified asphalt. A-Pal has a certain improvement effect on the low temperature performance of SBS-modified asphalt as shown by a low temperature crack resistance test. A-Pal-compounded SBS-modified asphalt features good storage stability in normal temperatures with the lowest critical compatibility temperature.

“…To address the issues of engineering properties among low water stability and the short service life of PAC, one possible solution is to use the modified asphalt binder to produce PAC to meet practical needs. Prominent researchers in asphalt modification have led systematic studies on crumb rubber/styrene–butadiene–styrene (CR/SBS) composite modified asphalt with continued efforts, which is a strong base for improving PAC’s engineering properties [ 23 , 24 , 25 , 26 , 27 ]. Based on Jin et al, different types of SBS such as linear SBS and radial SBS, different contents of SBS modifier, and sulfur content have impacts on the properties of the asphalt binder and asphalt mixture.…”

“…Based on Jin et al, different types of SBS such as linear SBS and radial SBS, different contents of SBS modifier, and sulfur content have impacts on the properties of the asphalt binder and asphalt mixture. Regarding the improvement of low temperature performance, the results show that under their experimental design, the optimum contents of SBS on asphalt binder and asphalt mixture are 6% and 4.5%, respectively [ 23 , 24 ]. Yu et al have conducted a thorough analysis on wet-process rubberized asphalt binder with warm mix asphalt (WMA) additives and have found that it is effective in alleviating the hardening and cracking of the virgin asphalt binder, exhibiting a more durable service life for the asphalt mixture [ 25 , 26 , 27 ].…”

Performance-Guided Design of Permeable Asphalt Concrete with Modified Asphalt Binder Using Crumb Rubber and SBS Modifier for Sponge Cities

The construction of sponge city is a major green innovation to implement the concept of sustainable development. In this study, the road performance of permeable asphalt concrete (PAC), which displays pronounced water permeability and noise reduction that are favorable for sponge cities, has been improved with a two-fold modification using styrene–butadiene–styrene (SBS) and crumb rubber (CR). Four percent SBS and three different ratios (10%, 15%, and 20%) of CR have been used to modify the virgin asphalt binder. The Marshall design has been followed to produce PAC samples. To evaluate the asphalt binder performance, multiple-stress creep-recovery (MSCR) test, linear amplitude sweep (LAS) test, and engineering property test programs including softening point test, penetration test, and rotational viscosity test have been conducted. Freeze–thaw splitting test, Hamburg wheel-tracking test, resilient modulus test, and permeability coefficient test have been performed to evaluate the asphalt mixture performance. The test results show that the addition of SBS and CR reduces the permeability coefficient, but significantly improves the high temperature performance, fatigue performance, and rutting resistance as well as the resilient modulus. However, the optimum rubber content should not exceed 15%. Meanwhile, after adding CR and SBS modifier, the indirect tensile strength (ITS) and tensile strength ratio (TSR) increase. It indicates that the moisture stability and crack resistance have been improved by the composite modification effect.

The aim of this paper was to assess the influence of the modification of the surface of dolomite and kaolin with SiO2 and TiO2 precursors, on the block copolymer styrene-butadiene-styrene (SBS) type thermoplastic rubber properties. These composite materials were obtained by compounding SBS with various ratio of powders. Based on the SEM images it can conclude that the powders were homogenously dispersed in to the SBS matrix. The dolomite particles can be clearly identified in the SEM images as particles of 10 micrometers. The samples obtained with modified dolomite have similar morphology. The EDS elemental distribution confirming a good corroboration between the elements of the dolomite, kaolin and titanium or silicon elements. Based on the thermal analysis according to the residual mass, the presence of 20% mineral phase can be confirmed. According to the DSC curves a strong stabilization of the composite appears, because of the presence of the mineral component. According to the physical-mechanical data all the composite materials exhibit improved mechanical properties. Additionally, the modification of the kaolin and/or dolomite bring important improvements in mechanical properties. The samples 13 and 14 exhibit high tensile and tear strength. These composites can be used for various applications, such as, for instance, soles for firefighters' footwear.
