【 摘 要 】

In the asphalt pavement design, determining reasonable structural parameters plays an important role in reducing early damage to the pavement and increasing use time of the pavement. Based on the optimized design, the dry-wet splitting strength and freeze-thaw splitting strength of AC-25 cold recycled emulsified asphalt mixture were studied. The results indicate that the dry-wet splitting strength of AC-25 cold recycled emulsified asphalt mixture is much higher than the technical requirements of the specification. The ratio of dry-wet splitting strength and the ratio of freezing-thawing cycle strength meet the indicators of the specification. Engineering application can refer to grading results of design.
