On smoothness control of asphalt mixing paver

In order to improve the smoothness of asphalt concrete pavement the working principle of asphalt mixing paver in smoothness control is studied,at the same time from the setting of base level,adjustment of sensor and other aspects the smoothness control of asphalt surface coat is discussed.Author points out parameter adjustment of asphalt paver are essential before construction in order to ensure original smoothness of asphalt concrete pavement.
