In order to study distribution regularity of heterogeneity of micro-structure of asphalt mixture, this paper which is based on fractal theory starts with aggregate distribution of asphalt mixture, and calculates fractal dimension of aggregate of ten groups of asphalt mixture in AC-16C type by using double log coordinates. It will evaluate indirectly heterogeneity of asphalt mixture through the analysis...
Paving overlay asphalt on an old road is generally adopted in road maintenance projects. Highway project is a linear project, diseases and the maintenance requirements of the component sections are very different. Firstly, the paper analyzes the decision-making process of maintenance program for asphalt pavement. Then, it points out that the road should be classified into some sections rationally...
It is serious that the early damage of asphalt mixture bridge pavement of our country, the damage of waterproof binding course is a major reason that causes the disease of bridge pavement, it is one of the most valid measures that resolve the weak quality problem of cementing material to guarantee and improve the endurance of bridges. Aim at the fatal weakness of waterproof binding course of traditional...
The damage of waterproof is a main reason that causes the bridge pavement diseases. Controlling the quality of cementing material is an effective measure to improve the endurance of bridge pavement. 'Two asphalt one aggregate' is put forward to solve the problem of 'white aggregate' appeared on the shearing destruction interface of synchronous crushed stone, The asphalt optimum dosage of 'two asphalt...
