摘要
改性沥青路面施工质量控制要求相比普通沥青更为严格,实践中存在许多施工工序处理不当,影响路面使用性能,发生早期破坏,达不到SBS改性沥青预计使用效果的案例。因此,有必要通过对大量改性沥青路面施工经验教训的总结并结合SBS改性沥青的特点,提炼出更科学可靠的施工质量控制的要点。
Because the requirement for construction quality control of modified asphalt pavement is stricter than the traditional asphalt. There are many cases where the improper construction processes influence the performance of pavement in practice, increasing early destruction of pavement and failing to achieve the expected effect of SBS modified asphalt. Therefore, it is necessary to summarize the massive experience of modified asphalt pavement construction and combine the characteristics of SBS modified asphalt to extract more scientific and reliable point in construction quality control.
