采用正交设计法 ,对影响水泥混凝土路面抗折强度的因素进行了试验分析。提出了在确保水灰比的前提下 ,适当减小粗骨料的最大粒径和保证一定的连续级配 ,可以提高其抗折强度。
The orthogonal design method was used to analyze the factors affecting the flexural strength of cement concrete pavement. Proposed to ensure the water-cement ratio under the premise of properly reducing the maximum particle size of coarse aggregate and to ensure a certain degree of continuous grading, can improve the flexural strength.
