Abstract Surface free energy is an important parameter to determine the work of adhesion between asphalt binder and aggregate, which related moisture damage mixture. In this study, sessile drop technique was performed obtain contact angle asphalt/aggregate different probe liquids. The surface energies aggregate were characterized on basis Owens-Wendt’s theory. It found that a convenient way static angle. A test procedure developed offer clear method prepare sample measure determined in study...
Physical properties of different fibers (mineral, cellulose, or carbon fiber) and their stabilizing reinforcing effects on asphalt mortar performance were studied. Scanning electron microscopy was used to study the effect fiber's microstructure mortar's performance. Laboratory tests mesh-basket draindown oven heating designed performed evaluate fibers' absorption thermostability. A cone penetration test flow resistance fiber-modified mortar. Results showed that fiber can form a...
Cold recycled asphalt mixtures (CRAM) are a cost-effective and environmentally-friendly way to reuse reclaimed pavement (RAP). This paper evaluates the rheological properties microstructure of mineral filler-asphalt mastic, filler-residue cement-residue mastic. Then, based on premise using 100% RAP with gradation that was determined experimentally, effects emulsified cement porosity, indirect tensile strength, strength ratio, dynamic stability, mechanical CRAM were evaluated. It found...
Abstract In the present study, curing process of epoxy asphalt was studied using Fourier transform infrared spectroscopy (FTIR) with attenuated total reflectance, fluorescent microscopy morphology, and surface free energy. FTIR utilized to track functional group changes in resin (part A) containing a agent B) at different times. It is proposed that (hardener) carboxylic acid. The reaction between carboxyl through which ester carbonyl formed, whereby acid molecules are bound together form...
Abstract A material extrusion (MEX) technology has been developed for the additive manufacturing of continuous carbon fiber–reinforced silicon carbide ceramic (C f /SiC) composites. By comparing and analyzing rheological properties slurries with different compositions, a slurry high solid loading 48.1 vol% viscosity was proposed. Furthermore, several complex structures C /SiC composites were printed by this MEX technique. Phenolic resin impregnation–carbonization process reduces apparent...
Lead zirconate titanate (PZT) piezoelectric composites used in transducers were fabricated via direct ink writing (DIW) combined with furnace sintering and resin impregnation. A ceramic slurry a volume fraction of 52 vol% suitable viscoelasticity was prepared. After post-process, the PZT specimens showed nanoscale grain size density 7.63 g/cm 3 , accounting for 97.8% theoretical density. The effects different printing rod spacing on electrical properties evaluated lucubrated. Finally, an...
This paper presents a laboratory study in styrene-butadiene-styrene (SBS) polymer modified asphalt including the dispersion process of SBS and performance without chemical reaction. Fluorescence microscope was adopted to characterize asphalt. The effects various factors on were studied by means particle size distribution, which obtained micrographs using Image-Pro Plus image analysis program. fundamental characteristics samples determined conventional test methods. results indicate that...
The influence of the addition one commercial wax, Sasobit, on two base asphalts was investigated as it relates to asphalt binder performance. Rheological effects wax were studied using a dynamic shear rheometer. A Fourier transform infrared (FTIR) spectrometer equipped with Golden Gate attenuated total reflectance (ATR) apparatus used investigate changes in chemical composition before and after wax. surface free energy binders determined by measurement static contact angle. Results showed...
An efficient method combined with fingerprint and chemometric analyses was developed to evaluate the quality of traditional Chinese medicine plant Penthorum chinense Pursh. Nine samples were collected from different regions during harvest periods, 17 components in form extracts simultaneously examined assess by using high-performance liquid chromatography. The hepatoprotective effects investigated assessing inhibition SMMC-7721 cell growth. results indicated that control accurate, stable,...
