Optimization Design and Research on Gradation of ATB-25

Abstract:

The ATB-25 mixture is optimized design base on the Bailey method. The skeleton embeded crowded structure of ATB-25 is better than that of AC-25 through analyzing the Bailey parameters, and the value of high temperature stability is 17.5% higher than that of AC-25, their water resistance are similar. The ATB-25 mixture is more suitable as pavement base materials. The proposed gradations belong to embedded crowed-solid structure which is verified by the calculated Bailey parameters, and the high temperature stability and water stability can be ensured. Combining with the highway pavement engineering project of Qujiang to Nanxiong, It is researched on the design of the mix proportion for asphalt treated base ATB-25 in the paper, and the suitable gradation design scheme is put out for the design and construction of highway pavement in high temperature and heavy duty area. The high temperature stability and water stability of ATB-25 which is designed based on the Bailey method can meet the requirements, and pavement performance can meet the design requirements.
