辽曙高粘度原油属低硫环烷基原油，密度大（ρ=0.997 79 g/ cm－3）,运动粘度大(υ100=1 223.9 mm2*s-1)，其性质类似于一般原油的渣油馏分。以该原油的减压渣油为原料,采用调合法制取沥青，并对其路用性能进行了评价，建立了Frass脆点和5 ℃针入度的关联方程。结果表明：采用调合方法可以制备出符合Q/SHR004-1998要求的AH-70、AH-90高等级道路沥青。该沥青的感温性能优良,粘弹区间（ΔT）大,超过了同类沥青的相应指标。利用所建立的Frass脆点和5 ℃针入度的关联方程，用5 ℃针入度可以预测Frass脆点。

The crude oil of No.1 zone of Liaoshu with high density （ρ=0.997 79 g*cm－3）and high viscidity(υ100=1 223.9 mm2*s-1) belongs in the low sulfur cycloparaffin group oil, and its property is familiar to that of residues of the general crude oil. In this paper, the paving asphalt was prepared by blending the vacuum residue from the crude oil and waste oil used as blender. The road performance of the paving asphalt was analyzed at the same time. The results showed that the property of paving asphalt could conform with the standard of Sinopec Q/SHR004-1998 very well. The temperature sensibility and viscoelastic behavior of Liaoshu asphalt excelled that of the others compared in this paper. A correlative equation between Frass brittle point and penetration at 5 ℃ was set up,with the equation and penetration at 5 ℃ Frass brittle point can be forecasted.
