近几年来,在城市道路建设中,仍有大量旧沥青路面需翻修重建工程。在翻修过程中,用铣刨机铣刨下来的沥青废料,回收和再生使用是具有很大经济价值的。众所周知,旧沥青混和料中,矿石料基本保持着原来的性状,其中的结合料沥青,主要理化性能指标也不曾发生质的变化,路面的损坏绝大部份仅是形状的变化,这些只需经过简单的再生处理,就可掺到新矿料中用于新路的铺筑。
In recent years, in the construction of urban roads, there are still a large number of old asphalt pavement needs renovation and reconstruction. During the renovation process, asphalt scraps milled with a milling machine are of great economic value for recycling and recycling. As we all know, the old asphalt mixture, the ore material remained the original traits, including binder asphalt, the main physical and chemical properties of the index has not changed qualitatively, pavement damage is mostly only the shape changes, these only After a simple regeneration process, it can be blended into the new mineral for paving new roads.
