Classification of Performance Grades of High Modulus Asphalt and Its Mixture: Taking China as an Example

Table 3

Classification standard of self-blending high modulus asphalt mixture.

Grades	Dynamic modulus (MPa)	Dynamic stability (times/mm)	Ultimate flexural-	Residual stability (%)	TSR (%)
			tensile strain (με)
Excellent	[17000, +∞)	[9600, +∞)	[3700, +∞)	[94, +∞)	[90, +∞)
Good	[15500, 17000)	[7300, 9600)	[3100, 3700)	[92, 94)	[87, 90)
General	[14000, 15500)	[5200, 7300)	[2300, 3100)	[90, 92)	[85, 87)
Poor	[0, 14000)	[2000, 5200)	[1900, 2300)	[80, 90)	[80, 85)

Note 1: the specification requires dynamic modulus >14000 MPa, which is based on the specification requirements.
