集料配合比可选用的设计方法很多,而各种方法在实际工程中的应用效果差别较大。文章通过对“中值型选择法”和“粗放型选择法”结合实际工程实验结果对比分析,认为在热拌沥青混合料路面配合比设计时选用“中值型选择法”较为合理。结论具有重要的实际工程应用价值。
Aggregate mix can choose a lot of design methods, and a variety of methods in practical application of large differences in the application effect. By comparing the “median selection method” and “extensive selection method” with the actual engineering experiment results, the article thinks that it is more reasonable to choose the “median selection method” when designing mix proportion of hot asphalt mixture. Conclusion has an important practical application value.
