本研究在结合以往研究的基础上，在一定的调配工艺下，研究了煤沥青不同添加

本研究在结合以往研究的基础上，在一定的调配工艺下，研究了煤沥青不同添加比例及粒径大小对混合沥青三大指标（软化点、延度及针入度）的影响，建立煤沥青添加比例、粒径大小和混合沥青性能指标的二维关系。对实验所得数据进行进一步处理分析，以煤沥青的比例、粒度以及混合沥青的路用性能作为三个变量，将实验数据空间化，运用Gauss2D函数将空间三维散点拟合成三维曲面，并整理出函数关系。接着对模型进行多项式特定简化，利用Matlab对方程组进行求解分析。根据求解的结果，对调整工艺参数或改性过程进行了分析讨论。

結果 (英文) 1:

On the basis of previous research, this study, certain deployment process, studied different coal tar pitch ratio and grain size on mixing asphalt three indicators (softening point, ductility and penetration) influence established ratio of coal tar pitch, diameter and mixing asphalt performance of two-dimensional relationship. Analysis of experimental data for further processing, coal tar pitch, size and road performance of asphalt mixture as three variables, the experimental data of space using Gauss2D function to three-dimensional scatter fitted to three dimensional surface and sorting out the function. Then the polynomial to model a specific simplified, using Matlab to solve the equations. According to the results, the adjustment or modification of process parameters were analysed and discussed.

結果 (英文) 2:

In this study, combined with previous studies, based on the allocation of certain processes, the study of different coal tar addition ratio and particle size of the three major indexes mixed asphalt (softening point, ductility and penetration) the impact of the establishment of coal asphalt addition ratio, a two-dimensional relationship between particle size and mix asphalt performance index. Experimental data obtained for further processing and analysis, in a ratio of coal tar pitch, size and mix asphalt road performance as the three variables, the experimental space-based data, the use of three-dimensional space Gauss2D function will scatter fitted three-dimensional surface, and finishing the function. Then the model is simplified polynomial particular, the use of Matlab to solve equations analysis. According to the results of solving for adjusting the process parameters or the modification process were discussed.

結果 (英文) 3:

In this study, based on previous studies, in the deployment of a certain process, study the coal asphalt of different proportion and size of mixed asphalt three indicators (softening point, ductility and penetration) influence, establish coal tar addition ratio, particle size and mixed asphalt performance index of two-dimensional the relationship between. The experimental data were further analyzed, using coal tar pitch ratio, particle size and mixed asphalt pavement performance as the three variables, the experimental data of space, using the Gauss2D function will be synthesized 3D scattered 3D surface, and sort out the function relation. Then carries on the polynomial to the model to simplify, uses the Matlab to carry on the solution analysis to the equation group. According to the results of the solution, the process parameters and the modification process were analyzed and discussed.
