Rapid base layer repairing method based on micro-crack characteristic of semi-rigid base layer material
The invention discloses a rapid base course repairing method based on the micro-crack characteristic of a semi-rigid base course material, and relates to the field of municipal road and highway pavement renovation, the method comprises the following steps: S1, obtaining the increasing rule of the modulus of the semi-rigid base course material along with the age; s2, constructing a finite element model to simulate and analyze the mechanical response of the asphalt pavement in different base crack states, calculating the stress condition of the surface layer, and constructing a relation curve between the stress of the surface layer and the cracking state and age of the base layer; s3, establishing a test road section, and correcting the parameters of the relationship between the surface layer stress and the age calculated by the finite element model through test data; s4, obtaining the cracking state of the base layer and the change rule of the rigidity characteristic along with the age by obtaining the internal stress state of the surface layer; and S5, if the internal stress of the base layer is detected to be abnormal, analyzing the abnormal condition, and evaluating whether the weight limiting measure needs to be intervened or not according to a preset threshold value. The defects of high cost, easy cracking and long period are overcome.
本发明公开了一种基于半刚性基层材料微裂特性的基层快速修复方法，涉及市政道路及公路路面改造领域，该方法包括以下步骤：S1、获取半刚性基层材料的模量随龄期的增长规律；S2、构建有限元模型，以仿真分析在不同基层裂缝状态下沥青路面的力学响应，同时计算面层受力情况，构建面层受力与基层开裂状态及龄期的关系曲线；S3、建立试验路段，并通过试验数据修正有限元模型计算出的面层受力与龄期关系的参数；S4、通过获取面层内部应力状态，得到基层开裂状态及刚度特性随龄期的变化规律；S5、若检测到基层内部应力出现异常，则分析异常情况，并根据预设的阈值来评估是否需要干预限重措施。解决成本高、容易开裂，周期久的缺点。
