The invention discloses a durable high-modulus
asphalt mixture based on hard
asphalt particles. The
asphalt mixture comprises 100 parts by
mass of mineral aggregate and 5.3-5.7 parts by
mass of asphalt, wherein the mineral aggregate comprises a limestone aggregate accounting for 96-98% of the total
mass of the mineral aggregate, and limestone mineral
powder accounting for 2-4% of the total mass of the mineral aggregate; and the asphalt is a compound of number 70 road
petroleum asphalt and the hard asphalt particles. The asphalt mixture improves the
gradation of the mineral aggregate, so that a coarse aggregate forms a good skeleton structure, and the shear property and the compressive property of the mixture are improved; and the property of asphalt
adhesive cement in the mixture is improved by adding an appropriate amount of mineral
powder, so that the surface of the mineral aggregate has appropriate asphalt
membrane thickness. Therefore, the mixture is good in high temperature property, easy to compact, and excellent in
fatigue resistance and durability; the capacity of a pavement for resisting damage of a track and the like can be improved if the mixture is used in a road middle surface course; the construction cost can be lowered; and the service life and the maintenance cycle of the pavement can be prolonged.
