Phenomenon: compaction does not meet specifications. In the face of insufficient compaction layer, thin strips of wood with a fingernail or the surface of the pellets dial LO pick, the pellets are loose or provoke the phenomenon.

Analysis: The master rolling speed, rolling mobile asphalt mixing plant method is wrong. Asphalt mixing temperature is too high, there are scorch phenomenon, asphalt adhesion loss, despite repeated rolling, but the integrity of the surface layer is not good, still half loose state. When the surface layer of compacted asphalt mixture temperature is low, although the asphalt cover wrap is good, but has been gradually losing sticky asphalt compaction was loose in the state, it is difficult compaction molding. Rainy construction, asphalt water film is formed, the impact of mineral aggregate and asphalt binder and asphalt mixture between RCC, the moisture evaporates water vapor formed by the closure, affecting the pavement effectively compacted. Compacted thickness is too large or too small.
