“…3 Therefore, modified asphalt has become a hot topic in recent decades. [4][5][6] There are mainly three kinds of polymers in modifying asphalt, rubber, resins, and plastics. [7][8][9] Crumb rubber (CR) and ethylene vinyl acetate (EVA) are used as modifiers for modified asphalt in this research.…”

Crumb rubber (CR) and ethylene vinyl acetate copolymer (EVA) were adopted as asphalt modifiers. Routine tests, softening point, penetration, and ductility were used to evaluate the basic properties of crumb rubber and ethylene vinyl acetate copolymers (CR/EVA) modified asphalt. The segregation experiment measured the storage stability. Modern test methods such as fluorescence microscopic photography technology was used to study stability of polymer modified asphalt. Infrared spectrum experiment was used to analyze the composition differences of the upper part and lower part of CR/EVA modified asphalt. Matlab software was employed to fit out the formulae of ductility, penetration, and softening point difference of modified asphalt and shearing temperature, shearing time and shearing rate separately. Compared with base asphalt, the properties of CR/EVA modified asphalt have been greatly improved. The formulae which were fitted out by Matlab software showed that the shearing time was the foremost factor affecting the properties of CR/EVA modified asphalt, followed by shearing temperature, and the last was shearing rate. The conclusions which were fitted by orthogonal experiment were basically consistent with the results of formulae which were fitted out by Matlab software.

“…Crumb rubber (CR), which is obtained from grinding the scrap tires, has been widely used in construction and industry. Particularly, CR has been used in the asphalt industry for more than four decades (Xiao and Amirkhanian, 2009;Xiao et al, 2009a;2009b;2009c). For instance, CR can be used as a bitumen modifier instead of expensive polymers such as styrene butadiene styrene (SBS) and styrene butadiene rubber (SBR) to reduce construction costs and energy consumption.…”

Abstract:In this study, the efficiency of bitumen and asphalt mixtures modified with crumb rubber (CR) and recycled glass powder (RGP) is evaluated. From an environmental point of view, the application of RGP in asphalt mixtures is considered beneficial since it prevents accumulation of waste glass in the natural environment. Rheological and mechanical properties of modified bitumen samples were investigated by laboratory methods such as bitumen conventional tests and dynamic shear rheometer (DSR), and also by asphalt mixture performance tests including Marshall stability, indirect tensile strength (ITS), compressive strength, and indirect tensile stiffness modulus. The results showed that the application of RGP in place of CR has no negative impact on the efficiency of bitumen and asphalt mixtures and even improves their engineering properties except for the toughness index (TI). Moreover, a modification with 5% CR and 5% RGP in asphalt mixtures results in the best overall performance.

“…It is estimated that only in 2010 about 630 Mt of HMA and 560 Mt of natural aggregates were consumed in China [2]. Recycling of inferior natural resources [3] and some wastes such as demolition waste [2,4], steel slag [5][6][7], reclaimed asphalt pavement (RAP) [8,9] etc. in asphalt mixture is a promising way to reduce the demand of high-quality natural resources.…”
