Material and building method of highway bed

摘要: A material for highway bed contains the mixture of sand, clay and broken stone (55-80 wt.%), light burnt magnesium (9-30), halogen flakes (10-25), modifier (0.55-1.35), water-proofing agent water-reducing agent. method building up with said is also disclosed, which features use Cl-O-Mg cementing to solidify into a whole without local deformation under heavy load. Its advantages include low water content absorption, high freeze-thaw resistance no cracking "generating slurry".
