CN107014706A 一种沥青路面用的灌缝胶低温及疲劳性能评价方法 无效 - 驳回

一种沥青路面用的灌缝胶低温及疲劳性能评价方法
摘要：
本发明属于公路沥青路面预防性养护技术领域，尤其涉及一种沥青路面用的灌缝胶低温及疲劳性能评价方法，包括如下步骤：(1)进行低温拉拔试验；(2)进行间接拉伸疲劳试验；(3)进行低温拉拔试验和间接拉伸疲劳试验的评定方法；本发明的低温拉拔试验模拟灌缝胶修复路面后在低温最不利条件下的受到外力拉伸作用后的抗开裂性能；本发明的间接拉伸疲劳试验模拟沥青路面用灌缝胶修复后在外界荷载作用下的抗疲劳性能，本发明提供的沥青路面用的灌缝胶低温及疲劳性能评价方法更接近实际路面裂缝修复情况，可以定量、快速的判断灌缝胶对沥青路面裂缝修复后的低温、疲劳性能。
摘要（英）：

The invention belongs to the technical field of preventive maintenance of highway asphalt pavements and particularly relates to a method for evaluating the low-temperature performance and the fatigue performance of a crack filling adhesive for an asphalt pavement. The method comprises the following steps of (1) carrying out low-temperature drawing test; (2) carrying out indirect tensile fatigue test; and (3) carrying out evaluation on the low-temperature drawing test and the indirect tensile fatigue test. The low-temperature drawing test is used for simulating the cracking resistance of the pavement repaired by the crack filling adhesive under the tension action of an external force under the most unfavorable low-temperature condition; and the indirect tensile fatigue test is used for simulating the anti-fatigue performance of the pavement repaired by the crack filling adhesive under the action of an external load. The method for evaluating the low-temperature performance and the fatigue performance of the crack filling adhesive for the asphalt pavement is closer to the actual pavement crack repairing condition and is capable of quantitatively and quickly judging the low-temperature performance and the fatigue performance after cracks of the asphalt pavement are repaired with the crack filling adhesive.
