Title:
RESIN COMPOSITION FOR WATER-PERMEABLE PAVEMENT MATERIAL
Document Type and Number:
Japanese Patent JP2611918
Kind Code:
B2
Abstract:
PURPOSE: To obtain a resin composition capable of giving a water-permeable pavement which is free from defects over long, such as the debonding of in organic aggregate particles caused by external stress, by mixing a liquid epoxy resin with an amine hardener and a xylene/formaldehyde resin.
CONSTITUTION: A liquid epoxy resin (A) (e.g. a liquid bisphenol A epoxy resin) is mixed with an amine hardener (B) (e.g. a xylylenediamine modified with acrylonitrile) and a xylene/formaldehyde resin (C) to produce the objective composition. The amount of the ingredient (C) is preferably 3-50 pts.wt. per 100 pts.wt. the sum of the ingredients (A) and (B). A curing accelerator (e.g. hydroquinone), an antioxidant, a thixotropic agent, etc., may further be incorporated. Since this composition has a high initial strength and a high tensile elongation at break and is reduced in deterioration by weathering, a waterpermeable pavement which does not suffer troubles such as cracking over long can be laid with the composition.
