查询词典 performance evaluation

Three types of base asphalt and six SBS were used to produce SBS modified asphalt. The interaction of SBS modified asphalt was discussed in different states between the base asphalt and SBS based on their compositions. Through the traditional tests, such as penetration, soften point and ductility, and US SHRP tests, the results indicated that influences to affect the temperature susceptibility, high and low temperature performance, aging characteristics are base asphalt, SBS types and their dosages. The functions of penetration to viscosity and complex shear modulus G~* to complex dynamic shear viscosity η~* were set up, and then theviscosity-temperature susceptibility of wide temperature span and the calculation method of low temperature viscosity were obtained."Process" evaluation criterions, high grading critical temperature T_ and low grading criticaltemperature T_ , were suggested according to the high and low temperatureperformances of SBS modified asphalt. Using the experience of Repeated Creep and Recovery Test for Binders, a new high-temperature evaluation index,modification rutting factor G~*~(-9) was obtained. The results after RTFO and PAV aging indicated that traditional tests didnt differentiate base asphalt and SBS modified asphalt, but dynamic mechanics temperature spectrum and G*-5 black chart clearly reflected the influence of aging to the SBS modified asphalt. With the IR and GPC tests, the reason of aging to the SBS modified asphalt were due to asphalt phase oxygenated and SBS phase depredated.

论文选择3种油源的基质沥青和6种SBS改性剂制备改性沥青，通过分析基质沥青和SBS改性剂的组成结构特点，得出了不同状态下SBS改性沥青的SBS与基质沥青的相互作用机理；通过针入度、软化点、延度等常规试验以及美国SHRP试验，分析了基质沥青、SBS改性剂类型与剂量对SBS改性沥青的温度敏感性、高低温特性及老化特性的影响；建立了针入度-粘度、复数模量G~*-复数粘度η~*的换算关系，得出了宽温度域的粘温指数VTS和较低温度下粘度的计算方法；通过高低温性能分析提出了&过程&评价参数高温等级温度T_和低温等级温度T_；借鉴重复恢复与蠕变试验研究成果，得到了SBS改性沥青高温评价指标改进型抗车辙因子G~*~(-9)；RTFO和PAV老化后的性能试验结果表明，常规试验难以区分SBS改性沥青与基质沥青的差异，而动态力学温度谱、G~*-δ黑斑图可以反映老化作用对SBS改性沥青的影响，且通过IR试验和GPC试验得出SBS改性沥青老化是沥青相的氧化和SBS的降解共同引起的；通过不同温度下SBS改性沥青混合料的旋转压实SGC试验，根据粘度与剪变率的关系，提出用剪变率60(1／s)测试SBS改性沥青的粘温曲线，并按照0.17±0.02Pa.s和0.28±0.03Pa.s确定施工温度。

The feasibility of neural network application to asphalt concrete pavement performance forecast is set forth. Three main environmental factors-traffic, rainfall, temperature, which can lead to the direct change of pavement performance are used as the input layer of neural network. The performance indexes of asphaltum concrete pavement, i.e. dilapidation rate, smoothness, deflection, friction coefficient are used as output layer. The relation between environment factor and pavement performance is acquired by introducing the module of BP Neural Network in MATLAB.
