Totally 60 semi-circular bending specimens cored from superpave gyratory compactor with three groups of notch depths are tested at the temperature of-10 and 20℃ The experimental results reveal good repeatability in EAM characterization. The tensile strength ratio of SCB to the indirect tensile test is at a range of 1.4 to 1.7, and the ultimate strength of EAM is exponentially dependent on the notch depths. At the test temperatures, the critical J-integral value of EAM is much higher than that of hot mix asphalt with thermoplastic asphalt binder. The response mode of EAM changes from ductile mode to brittle mode and the fracture energy increases 30% when temperature decreases from 20 to-10℃, while its critical J-integral value decreases only 15%.

结果表明，环氧沥青混合料的半圆弯曲试验结果复现性好；由非切口试件的半圆弯曲试验与标准间接拉伸试验所测得的环氧沥青混合料的抗拉强度，其比值在1.4~1.7之间，且SCB抗拉强度与切缝深度指数相关；在20℃与－10℃试验条件下，环氧沥青混合料具有比热塑性HMA高得多的临界J-积只分值；当温度由20℃降至－10℃时，环氧沥青混合料的响应模式由延性变为脆性，断裂能增加30%，而临界J-积分值下降15%。

The plant floating-bed technology application in Miaojia river showed that the water quality of the plant foating-bed technology applied had preceded evidently than the comparing water, though the water quantity was exchanged largely. There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.
