“…They observed that maleic anhydride improved the cohesive strength at high temperature and enhanced cracking resistance at low temperature. Another study investigated the effect of maleic anhydride grafted polymer (SEBS-g-MA) on the storage stability of modified bitumen and it was found that SEBS-g-MAH -modified bitumen showed better storage stability than the SEBS-modified bitumen [301]. In general, the addition of maleic anhydride improves the properties of modified bitumen significantly due to its high reactivity, which promotes the chemical interaction between bitumen and polymer.…”

The failure of bituminous pavements takes place due to heavy traffic loads and weather-related conditions, such as moisture, temperature, and UV radiation. To overcome or minimize such failures, a great effort has been put in recent years to enhance the material properties of bitumen, ultimately improving field performance and increasing the pavement service life. Polymer modification is considered one of the most suitable and by far the most popular approach. Elastomers, chemically functionalised thermoplastics and plastomers * (* Note: notwithstanding the fact that in Polymer Science the word ‘plastomer’ indicates a polymer with the simultaneous behaviour of an elastomer and plastics (thermoplastics), this paper uses the term ‘plastomer’ to indicate a thermoplastic polymer as it is more commonly found in Civil and Pavement Engineering.) are the most commonly used polymers for bitumen modification. Plastomers provide several advantages and are commonly acknowledged to improve high-temperature stiffness, although some of them are more prone to phase separation and consequent storage instability. Nowadays, due to the recent push for recycling, many road authorities are looking at the use of recycled plastics in roads. Hence, some of the available plastomers—in pellet, flakes, or powder form—are coming from materials recycling facilities rather than chemical companies. This review article describes the details of using plastomers as bitumen modifiers—with a specific focus on recycled plastics—and how these can potentially be used to enhance bitumen performance and the road durability. Chemical modifiers for improving the compatibility between plastomers and bitumen are also addressed in this review. Plastomers, either individual or in combination of two or three polymers, are found to offer great stiffness at high temperature. Different polymers including HDPE, LDPE, LLDPE, MDPE, PP, PS, PET, EMA, and EVA have been successfully employed for bitumen modification. However, each of them has its own merit and demerit as thoroughly discussed in the paper. The recent push in using recycled materials in roads has brought new light to the use of virgin and recycled plastomers for bitumen modification as a low-cost and somehow environmental beneficial solution for roads and pavements.

“…Various investigated polymers included plastomers (e.g., polyethylene (PE), polypropylene (PP), ethylene vinyl acetate (EVA), ethylene butyl acrylate (EBA)) and thermoplastic elastomers (e.g., styrene butadiene styrene (SBS), styrene isoprene styrene (SIS), and styrene ethylene butylene styrene (SEBS)) [3][4][5][6][7][8][9], although none of these were initially designed for bitumen modification. These polymers were reported to lengthen the bitumen's fatigue life, stiffness at high temperatures, cracking resistance at low temperatures, and moisture resistance.…”

Polymer modified asphalt emulsions offer superior performance and lifespan as compared to conventional asphalt emulsions or hot mix asphalt surface treatments, as well as reduced life cycle costs. This study’s objective was to examine the characteristics of latex-modified asphalt emulsions using a range of tests, including those for softening point, penetration, ductility, viscosity and solubility. In order to determine the optimal latex modified asphalt emulsion, latex was added into emulsion type CSS-1hP at various ratios ranging from 1 to 9 percent, with 2 percent interval while 0 percent serving as the control. From the experiments described, the best latex modified asphalt emulsion measurement was selected using a decision matrix analysis. Decision Matrix Analysis was performed to determine that asphalt emulsion with 5 percent latex is the best choice since it offers the highest quality polymer modified asphalt emulsion.

“…The modification mechanism can be explained as follow: polymer absorbs the oily compounds of bitumen as aromatics and saturates. Beside the type of the polymer used in the modification production conditions of PMB are also effects the characteristics of the sample [2][3][4][5][6][7].…”

Styrene-Butadiene-Styrene (SBS) is one of the most commonly used copolymer in the PMB production. SBS modification results in different material characteristics on the neat bitumen depending on the SBS type and of course the amount of the SBS used in the modification. Within the scope of this study, morphological characterisation of SBS modified samples involving different amount of SBS copolymer (4%, 5% and 6%) were examined by using innovative microscopies as AFM and CLSM. The topographic and phase properties of the PMB samples were obtained by using AFM and the dispersion and interaction of SBS copolymer with the bitumen were interpreted based on the images obtained by CLSM. As a result it was concluded that, the amount of the copolymer used in the modification process directly effects the morphological properties of the final product (PMB).
