High-temperature-resistant rut pavement structure suitable for silt roadbed
The invention discloses a high-temperature-resistant rut pavement structure suitable for a silt roadbed, and belongs to the field of road engineering. The pavement structure comprises a silt and solidified soil roadbed, the macropore cement stabilized macadam semi-rigid base layer, the reinforced graded macadam base layer, the modified potassium magnesium phosphate cement emulsified asphalt mixture lower surface layer, the medium grain type drainage asphalt mixture middle surface layer, the fine grain type drainage asphalt mixture upper surface layer and the ceramic particle wearing layer are sequentially paved on the roadbed from bottom to top. Compared with the prior art, the pavement structure disclosed by the invention has good waterproof and drainage performance and high-temperature rutting resistance, is particularly suitable for a silt roadbed, can avoid roadbed diseases such as cracking, rutting damage, pit slots and uneven subsidence after a dry-wet cycle period, and prolongs the service life of the pavement structure.
本发明公开了一种适用于粉土路基的抗高温车辙路面结构，属于道路工程领域。所述路面结构包括粉土固化土路基，以及自下而上依次铺筑在路基上的大孔隙水泥稳定碎石半刚性基层、加筋级配碎石基层、改性磷酸钾镁水泥乳化沥青混合料下面层、中粒式排水沥青混合料中面层、细粒式排水沥青混合料上面层以及陶瓷颗粒磨耗层。与现有技术相比，本发明路面结构具有良好的防排水、抗高温车辙性能，特别适用于粉土路基，能够避免干湿循环周期后出现开裂、车辙破坏、坑槽、不均匀沉陷等路基病害，提升路面结构使用寿命。
