Economical and environmentally friendly as it reuses existing asphalt pavement.


This is a cold-in-place recycling method in which aged asphalt pavement that has developed alligator cracks is crushed in-place and mixed with the underlying road base material while adding cement, etc. to create a new stabilized base courase.


  1. Economical since existing pavement material can be used effectively.
  2. Unlike the replacement works, there is no need to replace existing old materials with new materials, and the construction period can be shortened.
  3. Strong road base can be built.
