Title:

COMPOSITION FOR PAVEMENT MATERIAL, MODIFIED ASPHALT, ASPHALT MIXTURE FOR PAVEMENT AND PAVEMENT

Document Type and Number:

Japanese Patent JP2007016535

Kind Code:

A

Abstract:

To provide an asphalt mixture providing desired density and having high strength by excellently dispersing waste plastic composed of one kind or two or more kinds of PS, PP and PE without requiring to raise the manufacturing temperature of the asphalt mixture by several 10 °C while reducing the quantity of asphalt to be used by a waste plastic adding quantity at a maximum by imparting the function as a binder to a composition in the asphalt mixture for pavement.

This asphalt mixture for the pavement is formed by mixing the composition for the pavement, asphalt and an aggregate or mixing modified asphalt and the aggregate. The modified asphalt is formed by mixing the composition for the pavement and the asphalt. The composition for the pavement is formed by mixing the waste plastic and waste oil. The waste plastic is composed of one kind or two or more kinds of polystyrene PS, polypropylene PP or polyethylene PE. The waste oil is composed of waste edible oil and/or waste engine oil.
