SMA路面的设计与施工

SMA沥青码蹄脂碎石混合料是近年来国际上应用较广的新型沥青混合料。它适合于经济高速发展下道路承担重交通荷载和高轮胎压力的要求。它各方面的优异性能是原来的密级配沥青混凝土路面无法比拟的,特别是抗高温车撤和抗滑能力。该文参阅国内外资料,结合自身参与设计、施工的经验,较系统地对SMA路面设计与施工中的相关技术问题进行了总结,并强调了影响质量的关键指标。

Design and Construction of SMA Pavement

The SMA asphalt mastic broken stone mixture is a new asphalt mixture very conspicuously and internationally popularly in the recent years. The mixture is suitable for the requirements of the roads bearing the heavy traffic load and the high tyre pressure under the high-speed economical development. It is hard to compare its excellent performances with the originally densely graded asphalt concrete pavement in various aspects,especially anti-high-temperature track and anti-slide capacity.
