Title:
SOIL PAVEMENT MATERIAL
Document Type and Number:
Japanese Patent JP2018111785
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a soil pavement material having quick curability, excellent in resistance to freezing damage and excellent in weedproofness for overcoming problems with a conventional cement solidifying agent (curing agent), a magnesia solidifying agent and further a solidifying agent using calcium aluminate slag that curing time is long and it receives freezing damage at low temperature, that shrinkage amount is large and cracking is generated, and that weedproof effect is low.SOLUTION: There are provided (1) a soil pavement material containing calcium aluminate having vitrification rate of 70% or more, CaO/AlOmolar ratio of 1.0 to 2.7 and impurities of 15 mass% or less, gypsum, a water repellent and a soil, (2) a soil pavement material according to (1), further containing cement.SELECTED DRAWING: None
