摘要
通过室内试验研究了不同种类高抗折强度路面混凝土的疲劳性能,并在相同应力水平以及相同荷载作用下与不同类型混凝土的疲劳性能进行了对比分析。结果表明:高抗折强度路面混凝土疲劳性能明显优于普通路面混凝土和高性能路面混凝土:加入掺合料后进一步改善了高抗折强度路面混凝土的疲劳性能.延长了使用寿命。
Through laboratory test, the fatigue property of different high bending strength pavement concrete is studied, which is contrasted with different concrete under the same stress level and load. By comparing it with normal concrete＇s and high performance pavement concrete＇s fatigue performance, the study shows that high bending strength pavement concrete has good fatigue performance. Especially added with admixture,it improves the fatigue performance and prolonges the service life of high bending strength pavement concrete.
