西藏地区级配碎(砾)石柔性基层设计与施工

Design and Construction of Graded Broken Stone(Gravel) Flexible Base in Tibet Area

通过对在西藏地区特殊自然条件下的级配碎(砾)石柔性基层的设计和施工方法进行研究,提出满足西藏特殊自然条件下的路面结构、材料组成及施工工艺,可使高寒、紫外线照射强烈、路面冻害严重、地质复杂、筑路材料缺乏的西藏地区的路面结构合理、经济耐久、安全可靠。

Through studying the design and construction method of graded broken stone（gravel） flexible base under the special natural condition of Tibet area, the pavement structure, materials composing and construction technology adapting to the special natural condition of Tibet are proposed, which can make the pavement is strong, the freezing injury building materials are lacking, structure in Tibet, where the weather is high cold, ultraviolet radiation of pavement is serious, the geologic condition is complex, the road is rational, economical, durable, safe and reliable.
