摘要
以辽宁新铁高速公路建设工程实例为依托,对超薄磨耗层SMA-5的材料组成和要求,目标配合比设计、性能验证等进行室内试验研究。从试验结果中可知,超薄磨耗层SMA-5具有稳定的骨架嵌挤结构,优良的抗高温稳定性和水稳定性,其路用性能也得到了进一步的验证。
Liaoning Xintie highway construction project examples as the basis, the paper has studied the material composition and requirements to ultrathin wear thin layer of SMA -5, the target mixture design, performance qualification test research. Seen from the test results, ultrathin wear thin layer of SMA -5 has the stable skeleton Interlocking structure, excellent resistance to high temperature stability and water stability. The road performance is also obtained the further validation.
