主要通过对指定旧路面回收的沥青参数指标(渗透性、粘结性)的测定特性的描述,建立主要参数与回收沥青间的相关数学模型。确定方程式并进行回归分析,通过研究将回收沥青性能与现有规范标准进行比较。道路实际年龄和沥青之间存在的细微关系满足方差在8E-05~0.0943之间的线性、指数、对数、二次幂、四次幂方程式。道路年龄对结合料针入度、粘性方面的影响显示出各自明朗的关系。研究显示,回收沥青可用于沥青混凝土路面建设,可保护环境和减少土地使用。
Mainly through the designation of the parameters of the asphalt pavement recycling (permeability, cohesion) measured characteristics of the description, the establishment of the main parameters and the correlation between asphalt recovery mathematical model. Determine the equation and conduct regression analysis, through the study will be recycled bitumen performance and existing standards for comparison. The minor relationship between the actual age of the road and the asphalt satisfies the linear, exponential, logarithmic, quadratic, and quadratic power equations with a variance between 8E-05 and 0.0943. The influence of road age on the penetration and viscosity of the binder shows its own clear relationship. Research shows that recycled asphalt can be used in asphalt concrete pavement construction, which can protect the environment and reduce land use.
