# Evaluation of Construction Asphalt Pavements Based Toposable Set Theory: A Case Study
## 6 Conclusions  
1. Combining the characteristics of construction control of asphalt pavements, a construction control assessment model is established using toposable set theory. Considering the actual situation, the weight calculation results are more reasonable and accurate by constructing a topologizable interval judgment matrix compared with the previously constructed fixed value judgment matrix, and combining the judgment matrix consistency test with the weight calculation enables the calculation steps to be simplified.
2. The model proposed in this paper is used to calculate that the construction control level of the case study is Grade II, and the characteristic value of the variable is j\({}^{*}\) = 2.4784, which is inclined to Grade III. It is verified that the model can evaluate the construction control of asphalt pavement more reasonably and scientifically, and can provide reference for the evaluation of construction control of asphalt pavement.
3. Compared with the assessment methods of existing specifications, the model can quantitatively assess the construction control rating level of asphalt pavements and better reflect the actual situation of construction control. It overcomes the shortcomings of other assessment methods, which are highly subjective and rough in calculation, and can objectively assess the construction control condition, providing reference for the construction control of similar asphalt pavements and improving the construction control scheme.
4. At the same time, it can be seen from the evaluation results that the mud content in aggregate and gradation in the mixing process need to be greatly improved in the subsequent construction process, and the detection and control of mud content and gradation should be strengthened to fully ensure the construction quality of asphalt pavement.
5. There are still some limitations in the research of asphalt pavement construction control technology in this paper. For example, due to the complicated construction process, some construction control indexes related to pavement performance may not be reflected in the construction quality control system, which needs to be further improved. The quantitative relationship between construction control indicators and pavement performance, as well as the degree of influence of variation of construction control indicators on pavement performance, need to be further discussed or determined through experimental analysis.
6. The causes of asphalt pavement damage include many features. Relevant practitioners should consider comprehensively the aspects of design, construction and maintenance.  
In terms of design, they can focus on the design idea of integrating pavement structure and pavement materials to improve the performance of asphalt pavement. In terms of maintenance, the focus is mainly prevention-oriented, combining prevention with treatment, long-term maintenance with regular inspection, and early detection and early treatment of problems, all of which not only improve the pavement performance, but also prolong the service life of the road.
