Aggregate & Material Modification


Ecobond modification of crushed stone, natural gravel, sands, etc. is utilized to:

  • Improve Shear Strength by increasing the cohesion without reducing the angle of internal friction
  • Reduce moisture sensitivity

Testing: Triaxial shear testing is the most informative system for  this kind of application but other shear strength tests can also be  used.


  • Sub bases
  • Selected layers
  • Crushed stone base courses
  • Gravel road wearing courses when combined with Ecobond spray-on applications
