道路沥青及沥青混合料使用性能气候区划的研究

On the Climatic Region Charts for Road Bitumen and Mixture Performances

本文分析了中国气候的特点及其对沥青路面的影响，提出以年最高月平均最高温度（通常为７月）作为反映高温抗车辙能力的气候指标，以年极端最低气温作为反映低温抗裂性能的气候指标，以年降水量作为反映沥青路面水稳定性的气候指标，根据我国６１５个气象台站的３０年数据资料分析，提出了我国沥青与沥青混合料使用性能气候分区标准的建议，以及温度和雨量的分区图。

The Climatic region charts for road bitumen and mixture performances are formulated in this paper in the light of china’s climate characteristics and the ef- fects of them on bitumen pavement performance,with the annual mean monthly highest temperature(usually in July)as on indicator for rutting- resistance per- formance of the pavements in high temperature,with the extreme annual lowest temperature as on indicator for anti- cracking performance of the pavement in low temperature,and with annual rainfall as on indicator for the water- stability of the pavement.In mapping out the charts,thirty year data record from 615 meteorologi- cal stations were utilizod
