Properties of Direct Coal Liquefaction Residue Modified Asphalt Mixture

Table 7

Performance of the asphalt mixtures.

Types	Dynamic stability/(times/mm)	Failure strain/	Residual stability/%	TSR/%
SK-90 asphalt mixture	943.88	2683	80.05	76.38
SBS modified asphalt mixture	2452.38	2798	84.40	84.15
DCLR modified asphalt mixture	2604.86	1552	83.64	83.78
DCLR-composite modified asphalt mixture	9867.65	3070	100.05	86.61

Note: DCLR: Direct Coal Liquefaction Residue; DCLR-composite: 2% SBS, 15% rubber powder and 10% DCLR by mass of SK-90 asphalt binder; and TSR: tensile strength ratio.
