  • One-pass paving technology for ultra-thick cement stabilized course

  • 2013/05/30  
  • In 2002,state-of-the-art super compactor and one-pass paving, rolling and compacting technology were used for the first time to pave ultra-thick cement stabilized course (30cm-40cm) instead of traditional paving by layer, which simplified construction, protected the water-stable base course of the pavement against premature damages caused by paving by layer and improper structural stress, improved work efficiency and brought down construction cost.

     

    The figure shows theultra-thick water-stable course paved with new one-pass paving technology. It can be seen that the water-stable course on the subgrade is still intact eventhe subgrade has been washed out and destroyed partially by a 100-year flood.
