The ASTM C666 procedure is the common test method used for evaluating the freeze-thaw durability of conventional concrete, and it has been adapted for evaluating the freeze-thaw resistance of pervious concrete; however, it is argued the test method does not represent the field conditions of neither conventional nor pervious concrete. This study mainly focused on an experimental program to evaluate the freeze-thaw durability of pervious concrete specimens using the JC446-91 test method, which measures the change in compressive strength and mass after exposure to freeze-thaw cycles, as an alternative for ASTM C666. Various parameters affecting the freeze-thaw durability of pervious concrete, namely water to cement ratio (W/C), air entrainment, inclusion of sand, and coarse aggregate size were experimentally examined, and the results were evaluated using statistical analysis. It was observed that replacing 8% of coarse aggregate with sand and using a higher W/C resulted in higher strength and an improvement in the freeze-thaw durability. Although the positive effect of air-entraining admixture (AEA) on freeze-thaw durability of pervious concrete has been manifested by previous researchers, it was not clearly observed in this study. Also, change in coarse aggregate size did not significantly affect the strength and freeze-thaw durability of pervious concrete. This study revealed that the conditions and number of cycles used in JC446-91 were inadequate to evaluate the freeze-thaw durability of pervious concrete, especially for strong mixes. Therefore, considering the criticisms against ASTM C666 in representing field conditions of pervious concrete, more compatible and realistic test methods are required to evaluate the freeze-thaw durability of pervious concrete.

ASTM C666程序是用于评估常规混凝土的抗冻融耐久性的常用测试方法，已适用于评估透水混凝土的抗冻融性；但是，有人认为这种测试方法不能代表传统混凝土和透水混凝土的现场条件。这项研究主要集中在一个实验程序上，该程序使用JC446-91测试方法评估透水混凝土样品的冻融耐久性，该方法可测量暴露于冻融循环后的抗压强度和质量的变化，以替代ASTM C666 。实验研究了影响透水性混凝土冻融耐久性的各种参数，即水灰比（W / C），夹带空气，夹杂砂和粗骨料尺寸，并使用统计分析评估结果。观察到用砂代替8％的粗骨料并使用较高的W / C导致较高的强度和冻融耐久性的改善。尽管以前的研究人员已经证明了引气剂（AEA）对透水混凝土的抗冻融耐久性的积极作用，但是在这项研究中并未清楚地观察到。同样，粗骨料尺寸的变化并没有显着影响渗透混凝土的强度和冻融耐久性。这项研究表明，在JC446-91中使用的条件和循环次数不足以评估透水混凝土的冻融耐久性，特别是对于强混合料。因此，考虑到针对ASTM C666代表透水性混凝土现场条件的批评，
