| 摘 要： | 天然砂砾作为基层虽粒径偏粗,但经过技术处理后基本达到规范要求的级配,一旦成形具有强度高、稳定性好、使用寿命长等优点.在中小交通量路段、二级以下中低级路改建项目、天然砂砾丰富地区,可以考虑设计天然砂砾基层,充分利用改建路段的行车碾压,可大大降低工程造价并能够取得良好的使用效果.

| Abstract: | The radius of natural gravel is too large for taking it as base course material, however, it can meet engineering requires after treatment and has much advantages, such as high intensity, good stability, long life. In the small volume highway, the reconstruction project which is under two grade lever highway and the rich natural gravel areas, we can consider using natural gravel as base course material. Fully using the roll of vehicle in reconstruction highway can lower project cost and get good using results. |
