“…Crumb rubber modified asphalt displays improved mechanical performance by reducing reflective cracking, fatigue cracking and increasing durability of the pavement [18][19][20][21]. A noteworthy consensus in application of crumb rubber, from an environmental viewpoint, is the utilization of tire wastes which need long time for natural degradation [22].…”

“…[2][3][4][5][6] Methods of recycling waste tire rubber are various, such as modifying road asphalt, producing thermoplastic elastomers, and making reclaimed rubber. [7][8][9] Only a small proportion of the waste rubber generated is recycled. This means that the quantities of waste rubber increase by about 9% per year in China.…”

In this experiment, tire rubber powder with 5.3% of sieve residue on mesh 40 is utilized in concrete. Rubber concrete mixture samples are prepared with three kinds of rubber powder, untreated, Na treated and Si pre-treated. The Na-treated powder and Si-treated powder are surface treated with saturated sodium hydroxide aqueous solution and silane coupling agent, respectively. The effects of this treatment are assessed by investigating the properties of the rubber concrete and the bonding at the interfaces between the powder and the concrete matrix. The results show that the compressive strength and flexural strength of the concrete mixture samples are reduced with the addition of rubber powder whether treated or not. The impact toughness and strain are higher than those of control samples due to the fact that amounts of energy are absorbed by the rubber powder. Further, it is in the samples prepared with Si-treated rubber powder where the two properties (impact toughness and strain) are highest, a result attributable to better bonding between the powder and the concrete matrix. Further investigation of the bonding at the interfaces between the rubber powder and the concrete matrix is carried out by the Fourier transform infrared spectroscopy and the environmental scanning electron microscope. Hydrogen and covalent bonds are found to have formed in the interface regions between the Si-treated rubber and the concrete matrix. The results indicate that the silane works as a 'bridge' in these regions and bonds the rubber and concrete more firmly by two types of bonds.

“…It reflects the asphalt viscosity at high temperatures, directly expresses and relates to the deformation rate; The ductility of asphalt is the sum of deformation when the asphalt binder is stretched; Viscosity are commonly used to determine the mixing and compaction temperatures of asphalt mixture; Penetration, softening point, ductility and viscosity tests were followed by the test procedures (JTJ052-2000) [7].…”

Nanomaterials (nano powdered rubber VP401, VP501 and sepiolite and CaCo 3 composites) were selected to improve the high-temperature and low-temperature performance of asphalt binder. Nanomaterial modified asphalt was prepared using the high shear machine. Laboratory experiments of asphalt binder and asphalt mixture were conducted to evaluate the properties of modified asphalt binder, including the penetration, ductility, softening point, viscosity, and etc. Also, asphalt mixture tests were carried out, such as the cleavage strength test, resilient modulus test, rutting test, water stability test and etc. Based on the test results, asphalt binder modified by 1% nano powdered rubber VP401 has better performance resistance to low temperature crack and rutting, compared to other nanomaterial modified asphalt binder.
