<正>针对南京市城市气候特点和道路交叉口的交通特点，采用AC-13C型、SMA-13两种矿料级配与两种沥青（道路石油沥青和改性沥青），共组成4种沥青混合料进行路用性能试验，研究了沥青混合料的水稳定性、高温稳定性、低温抗裂性、抗压强度和抗拉强度。通过对比分析，得出了适用于南京市道路交叉口路面上面层的沥青混合料组成以SMA-13为好。

The treatment of low temperature plasma to the surface of bamboo strips with or without hypodermis can improve the surface wettability and bonding strength of bamboo strips. In this research, treating time, treating distance and treating electrical power of low temperature plasma are investigated. The results show that the treating distance is the strongest affecting factor, followed by treating time and treating electrical power. The optimum technological parameters are as follows: treating time is 5s, treating distance is 10mm, treating electrical power is 650W. Under this treatment condition, bonding shearing strength of the bamboo strips with hypodermics increased by 143.9% with its key coefficient variance (CV) decreasing by 11.9%. Bonding shearing strength of the bamboo strips without hypodermis increased by 45.8% while its key coefficient variance (CV) decreasing by 6.5%.
