Abstract

With the increasing development of transportation infrastructure construction, the requirements for the performance of pavement materials are constantly increasing. To meet the drainage and compression requirements of the road surface, open-graded asphalt stabilized crushed stone base mixture has received widespread attention as a new type of road surface material. This article aims to prepare open graded asphalt stabilized crushed stone base application materials and compare their actual performance to evaluate their effectiveness in practical applications. Method and process: Combine ATPB30 and SACPB30 materials, carry out the grading design of the same main skeleton gap filling method, delimit the grading interval in the preparation process by calculating the average density of mineral aggregate, and ensure the authenticity and reliability of the mixture preparation. The best asphalt aggregate ratio is calculated, and the water seepage and compression resistance of the mixture are determined by combining the water seepage experiment and the rutting experiment, so as to complete the analysis of its key performance. Results: For the six randomly selected test nodes, combined with the measured data and information, it is finally concluded that the bending strain ratio of the airport pavement can reach more than 5.5, and each position of the airport pavement test is random, so the results of this calculation are more reliable. Conclusion: Under different backgrounds, through comparative tests from multiple angles and environments, the bending strain ratio of airport pavement finally reached more than 5.5, which indicates that the final performance analysis results obtained by combining the preparation of open graded asphalt stabilized macadam base mixture are more reliable and true, as shown: the smaller the particle size of SACPB30, the better its drainage performance during pavement construction, the corresponding compressive capacity has also been significantly improved, and the practical application effect in deformation control, anti fatigue treatment and crack resistance has been greatly optimized, indicating that the open graded asphalt stabilized crushed stone base mixture is more scientific and reasonable.
