谈 CAD 与 Excel 确定橡胶颗粒沥青混合料级配

摘要

在AC-13橡胶颗粒沥青混合料中，确定各种矿料的含量，可利用计算机软件AutoCAD与Excel电子表格相结合，绘制橡胶颗粒沥青混合料级配图，用软件绘图摒除了手工绘图效率低、时间长，曲线描绘不精确等缺点，可以不用编写程序，既避免不会因编程带来的工作停滞，又可以高效精确地确定出橡胶颗粒沥青混凝土中各种矿料的含量。%In the AC-13 rubber particles asphalt mixture,determine the content of mineral aggregate,can be combined with the computer soft-ware AutoCAD and Excel spreadsheet,drawing rubber particles asphalt mixture gradation figure. Use the drawing software eliminates the low effi-ciency of manual drawing,drawing a long time,the curves depict the imprecise,can not write a program,which can not only avoid not program-ming brings work stagnation,can efficiently and accurately determine the content of various mineral material of rubber particles in asphalt concrete.
