“…Among all polyolefin, the scientific community has directed particular attention toward polyethylene (PE) and polypropylene (PP). 13,15,[17][18][19][20][22][23][24][25]27,28,[32][33][34][36][37][38][39][40][41][42][43][44][45][46][47][48][49] These two thermoplastic semicrystalline polyolefins represent the globally most produced plastic materials employed for the massive production of tools of any sort. Given the relatively low melting temperatures (<170 C) and high thermal stability, these materials well fit in the production protocols of MBs from a practical point of view.…”

Linear-viscoelastic characteristics and performance are evaluated throughout the blending process of polyethylene and polypropylene with bitumen. Results indicate that type, form and percentage of polyolefin play a significant role in the time evolution of the composite's mechanical response. Toluene extraction of modified bitumen revealed, for the first time, the formation of a sponge-like polymer network. Visual inspection and Fourier transform infrared analysis of the polyolefins recovered after extraction indicates higher affinity of the polyethylene with bitumen in agreement with the rheological test results. The use of polypropylene is discouraged if rutting performance is a concern, and polyethylene in both pellets and powder form at 4%, and after 210 min of blending produces a modified bitumen with acceptable performance.

“…Nanomaterial additives have acquired considerable attention from pavement researchers for the formulation of durable, high-performance asphalt mixtures due to its superior-excellent properties such as wide surface area, excellent dispersion capacity, high absorption, excellent stability, and high chemical [11][12][13]. In order to enhance performance properties and long-term attitudes, a new group of asphalt mixtures has been established through a combination of different types of modifiers [14][15][16], such as polymers including styrene-butadiene-styrene (SBS), and nano-materials including (nano-silica, nano-clay, carbon nanotube).…”

Recently, polymer -nanocomposites were used to manufacture durable asphalt mixtures to replace the polymer modified binder, because of the remarkable properties and unique features of nanomaterials compared to conventional materials, such as their wide surface area and small dimensions, making it possible to be utilized as an additive for asphalt paving. Nanosilica particles (NS) are one of the latest minerals which likely integrate useful characteristics, such as huge surface area, good distributions, high absorption levels, high stability, and a high level of purity. Therefore, this paper is interested in studying the characteristics of nanocomposite-polymer modified asphalt. In laboratory work, a pure asphalt 60-70 penetration grade, has been modified separately with waste polypropylene polymer (WPP), and nanosillica composite polypropylene (NS/WPP) at different concentrations. As a result, two modified binders: waste polypropylene polymer- modified asphalt (WPP-MA), and nanosillica composite polypropylene modified asphalt (NSCPMA) were obtained. Traditional asphalt binder tests were performed for pure and modified binders such as penetration, ductility, flash and fire point test, softening point, and rotational viscosity. Also, storage stability test has been conducted to ensure the storage stability of binders at high temperatures. The results showed an improvement in physical properties and increase in mixing and compaction temperature due to the increase in stiffness of (NSCPMA). The results also indicated that the nanosillica composite polypropylene modified asphalt binders have good storage stability at high temperatures.

“…Rutting and fatigue cracking are the two main parameters dictating the life of asphalt pavement structure, hence the improvement of asphalt binders in order to sustain large stresses during pavement's service life is of significant importance. Rutting is accumulative permanent deformation in pavements layers due to the accumulation of strains over time under the repetitive traffic loadings [1,2]. Rutting in asphalt pavements lead to the reduction in both structural and service life performance of the pavement.…”

Polymer modified binders have been used for long time to improve the quality of asphalt pavement. This study investigates the effect of crumb rubber and latex on the properties of bitumen binders. Crumb rubber and latex were added to the control 60/70 pen grade bitumen. Four different proportions of crumb rubber and latex were considered in this study: 0%, 4%, 6% and 8% by weight of bitumen binder. The effect of crumb rubber and latex were evaluated through standard penetration and softening point tests as well as dynamic shear rheometer (DSR) test. Temperature ranges of 20 o C -40 o C were used for the DSR rheological testing. The results showed that the addition of crumb rubber and latex leads to a promising improvement on the binder properties. A reduction in penetration and an increase in softening point temperature were observed with the addition of either crumb rubber or latex, this indicates improvement in stiffness and rutting resistance. The analysis on DSR results also show that the modified binders have good rutting resistance.
