Effect of Polymer Additives and Process Temperature on the Physical Properties of Bitumen-Based Composites

Polymer modified bitumen (PMB) is a binder obtained by the incorporation of polymer into the bitumen by mechanical mixing or chemical reaction. This study deals with the modification of bitumen with three types of polymers (LDPE, EVA, and SBS) in the presence of filler (CaCO3). The morphological, mechanical, rheological properties, and thermal conductivity of the PMBs have been analyzed by scanning electron microscopy, tensile testing, melt flow index (MFI) measurements and hot wire method, respectively. The results indicate that the above-mentioned properties of PMBs are influenced by polymer and bitumen nature and its composition. The mechanical properties of composites prepared at different temperatures exhibit small differences. In general, the inclusion of polymer increases tensile strength and Young's modulus and reduces percentage strain and MFI values, also, polymer inclusion reduces the thermal conductivity values of the composites.

Effect of polymer additives on the physical properties of bitumen based composites
Doğan, Mehmet; Bayramlı, Erdal; Department of Polymer Science and Technology (2006)
Polymer modified bitumen is a binder obtained by the incorporation of various types of polymers in bitumen using mechanical mixing or chemical reactions. There are several factors affecting the properties of polymer modified bituminous composites such as; chemical composition of bitumen, kind of polymer and filler, compatibility of bitumen and polymer, amount of bitumen, polymer and filler, particle size of filler and process conditions. The main objective of this study is to determine the effects of polyme...
Effect of preparation parameters on the performance of conductive composite gas separation membranes
Gulsen, D; Hacarloglu, P; Toppare, Levent Kamil; Yılmaz, Levent (2001-02-15)
Mixed matrix composite membranes of a conducting polymer, polypyrrole (PPy), and an insulating polymer, polybisphenol-A-carbonate (PC) were prepared by a combined in-situ polymerization and solvent evaporation. Mixed matrix composite membranes were synthesized to combine the good gas transport properties of conductive polymer, PPy, with good mechanical properties of PC.
Effects of nanoparticles on thermal degradation of polylactide/aluminium diethylphosphinate composites
Kaya, Hatice; Özdemir, Esra; Kaynak, Cevdet; Hacaloğlu, Jale (2016-03-01)
We investigated the thermal degradation characteristics of polylactide (PLA) aluminium diethylphosphinate (AlPi) composites involving SiO2, halloysite (HNT) and organically modified montmorillonite (OMMT) via direct pyrolysis mass spectrometry. Presence of nanoparticles, SiO2, HNT and OMMT affected both thermal stability and relative yields of thermal degradation products of PLA/AlPi. The transesterification reactions and interactions between PLA and AlPi were depressed in the presence of SiO2 and HNT. The ...
Effect of structural isomerism and polymer end group on the pH-stability of hydrogen-bonded multilayers
Erel Göktepe, İrem; Demirel, A. Levent (2011-09-15)
Association of tannic acid (TA) with structurally isomeric poly(N-isopropylacrylamide) (PNIPAM) and poly(2-isopropyl-2-oxazoline) (PIPOX) has been examined at surfaces to understand the effect of different molecular arrangements in a polymer repeating unit of structural isomers on the construction and pH-stability of hydrogen-bonded multilayers. Films were fabricated using layer-by-layer (LbL) technique through hydrogen-bonding interactions primarily between carbonyl groups of neutral polymers and hydroxyl ...
Effect of Microfiber Reinforcement on the Morphology, Electrical, and Mechanical Properties of the Polyethylene/Poly(ethylene terephthalate)/Carbon Nanotube Composites
Yesil, Sertan; Koysuren, Ozcan; Bayram, Göknur (Wiley, 2010-11-01)
In situ microfiber reinforced conductive polymer composites consisting of high-density polyethylene (HDPE), poly(ethylene terephthalate) (PET), and multiwalled carbon nanotube (CNT) were prepared in a twin screw extruder followed by hot stretching of PET/CNT phase in HDPE matrix. For comparison purposes, the HDPE/PET blends and HDPE/PET/CNT composites were also produced without hot stretching. Extrusion process parameters, hot-stretching speed, and CNT amount in the composites were kept constant during the ...
