透水沥青路面在温州生态园工程中的应用

Application of Column-hammer Thrust-expanded Pile Method in Treatment of Miscellaneous Filling Subgrade

摘要:

针对透水沥青路面空隙率大、易发生沥青流淌、析漏严重且松散这一特点，通过析漏试验、抗车辙试验、飞散试验等，分析配比相同的透水沥青混合料各项性能随着拌和温度变化的规律，从而比选出适合温州地域气候的透水沥青混合料最佳拌和温度，并成功应用于温州生态园工程。

Abstract:

By describing the reinforcement mechanism, characteristics and design calculation method of the composite foundation with column-hammer thrust-expanded piles, and combined with the engineering cases, the application of this method in the treatment of miscellaneous filling subgrade of municipal road is introduced. Its technical advantages are outstanding, its engineering cost is cheap and its social benefit is remarkable, which has the broad application prospects.
