Title:
SMALL PARTICLE SIZE ASPHALT MIXTURE, SMALL PARTICLE SIZE ASPHALT PAVING METHOD, AND SMALL PARTICLE SIZE ASPHALT PAVEMENT BODY
Document Type and Number:
Japanese Patent JP2018071195
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an asphalt mixture, asphalt paving method, and asphalt pavement body capable of suppressing fuel consumption of a running vehicle and of reducing the emission of COby reducing generated rolling resistance.SOLUTION: An asphalt mixture contains aggregate and asphalt. The aggregate has a pass mass percentage of 90 to 100 mass% for a 4.75 mm sieve, a pass mass percentage of 10 to 25 mass% for 2.36 mm sieve, a pass mass percentage of 3 to 10 mass% for a 0.075 mm sieve, and a maximum particle size of 3 to 5 mm. The asphalt has a shear stress of 900 Pa or more, and is a polymer-modified asphalt H shape used for porous asphalt mixtures.SELECTED DRAWING: None
