In order to evaluate the high and low temperature rheological properties of different modified asphalt, this paper prepared types modifiers short-term aging asphalt (RTFOT), using dynamic shear rheometer (DSR) bending beam test (BBR) compare analyze deformation resistance stress sensitivity (organic inorganic) determine its PG classification, fitting parameters with help Burgers model. The low-temperature mechanical were evaluated by model; chemical composition asphalts was analyzed Fourier...
Purpose In order to evaluate the rheological properties of asphalt more comprehensively and effectively, explore discuss practicability relevant models in evaluation asphalt. Design/methodology/approach Based on viscoelastic theories, temperature scanning, frequency scanning multiple stress creep recovery (MSCR) tests different modified were carried out by dynamic shear rheometer (DSR) obtain parameters high time-temperature equivalence principle, main curve was constructed study a wider...
Purpose In order to give full play the function of noise reduction asphalt pavement, it is necessary understand its internal sound absorption mechanism. Therefore, purpose this study establish a micro model pore structure mixture with help finite element method (FEM), discuss mechanism pavement from perspective and analyze evaluate attenuation law structure. Design/methodology/approach The FEM was used microscopic mixture. Based on principle acoustics, characteristics were simulated....
There is significant interest in preparing packaging film from sustainable polysaccharides, especially hemicellulose (HC). Hemicellulose isolated wheat straw tends to aggregate into dissolved particles aqueous solutions and form poor films. When methylcellulose (MC) was added the HC solution, MC formed a HC-MC complex. With increased content, size of complex decreased, its surface charge at same time. 35 wt% HC, continuous layer structure. The with 75 showed more compact structure compared...
Purpose In order to determine the range of medium temperature zone road asphalt, it is hoped that evolution viscoelastic characteristics asphalt under state can be deeply explored. Design/methodology/approach this paper, needle penetration test and scanning were designed for 90# 70# bitumen as materials, boundary was accurately determined by data analysis method. A mathematical model established based on principal component analysis, a comprehensive evaluation index proposed evaluate means...
The overall appearance perception is affected by luminance accuracy and efficiency mostly.The surface prediction correlated with angle tone value was performed measuring modeling the paper model luminance.First, we used a rotating bracket designed to facilitate set angle.Then, from 5° 85° at interval of using bracket.Additionally, four primary color scales, cyan, magenta, yellow, black, were printed angle.The angle-ware tone-ware measured spectroradiometer, CS-2000.Finally, proposed...
The seasonal distribution coefficients of traffic volume have not been yet taken into account in asphalt pavement design China. Through comprehensive analysis on the assessed data and factors affecting monthly different areas, Harbin city, China has predicted determined using a back propagation (BP) neural network algorithm. research contents involve investigation volume, analysing mentioned coefficients, prediction determination application those etc. volumes year were calculated, results...
