Influence of Aggregate Gradation on Pavement Performance of Open-Graded Large Stone Asphalt Mixes
In order to analyze the influence of aggregate gradation on pavement performance of Open-graded Large Stone Asphalt Mixes (OLSM), this paper designs aggregate gradation of OLSM by numerical calculation method of varying I, and analyzes the relations between aggregate gradation and OLSM performances such as porosity, strength, water stability, high temperature stability and low-temperature crack resistance based on the results of an immersion large-scale marshall test, freeze-thaw split test, rutting test, and bending test at low temperature. The results show that with the value of I decreasing and content of coarse aggregate increasing, the porosity of OLSM increases, the strength, water stability and stability decreases, and low-temperature crack resistance increases first and then decreases. Based on the technical requirements, the reasonable aggregate gradation of OLSM is recommended.
