The durability of asphalt pavement is associated with the properties and performance binder. This work-study intended to understand impact blending Styrene-Butadiene-Styrene (SBS) conventional concrete mixtures calculating Optimum Asphalt Content (OAC) for mixture also; compare between SBS modified mixture. Two different kinds penetration grades, A.C. (40-50) (60-70), were improved 2.5 3.5% pol...

A physically based diffusion model is used to evaluate the sink effect of diffusion-controlled indoor materials and to predict the transient contaminant concentration in indoor air in response to several time-varying contaminant sources. For simplicity, it is assumed the predominant indoor material is a homogeneous slab, initially free of contaminant, and the air within the room is well mixed. ...

utilizing polymeric materials for damping mechanical waves is of great importance in various fields of applications such as military camouflage, prevention of structural vibrational energy transfer, and noise attenuation. this ability originates from segmental dynamics of chain-like polymer molecules. damping properties of styrene-butadiene rubbercontaining 10 wt% of monosize polystyrene partic...

Gel permeation chromatography (GPC), nuclear magnetic resonance (NMR) spectroscopy, and elemental analysis techniques were used to study the molecular characteristics of six commercially available styrene-butadiene-styrene (SBS) block copolymers which are mostly for modifying bitumen. The cis-1,4, trans-1,4, 1,2-vinyl units in polybutadiene (PB) parts styrene contents SBS investigated by means ...

In this investigation, rheological properties of three different polymer-modified bitumen compounds containing recycled polyethylene terephthalate (R-PET), crumb rubber (CR) and poly (styrene-butadiene-styrene) (SBS) are evaluated and compared. The modified samples were tested by a dynamic shear rheometer (DSR) where complex modulus (G*), phase angle (δ) and rutting resistance (G*/Sinδ) of spec...

Hard magnetic SrFe12O19 (SrM) nanoparticles were synthesized by a facile sonochemical reaction. The magnetic nanoparticles were then added to acrylonitrile-butadiene-styrene, polystyrene, polycarbonate, and poly sulfone to make magnetic nanocomposites. The magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. The strontium ferrite nanop...

Smart materials with reversible wettability have attracted a lot of attention for application in sewage treatment. In this work, pH-responsive polymer was prepared via the one-step free radical polymerization 3-(trimethoxysilyl) acrylate and 2-dimethylaminoethyl methacrylate. The obtained then coated hydrogenated styrene–ethylene–butadiene–styrene block copolymer to endow material switchable su...
