Low-temperature anti-cracking composite modified asphalt pavement structure
The invention discloses a low-temperature anti-crack type composite modified asphalt pavement structure, relates to the technical field of asphalt concrete pavements, and solves the problem that a low-temperature anti-crack type composite modified asphalt pavement structure is lacked on the basis of not influencing the bonding effect between a base layer and an asphalt surface layer and being low in construction difficulty. The technical problem of an asphalt pavement structure that the asphalt pavement generates temperature shrinkage cracking in a low-temperature environment can be reduced; the structure comprises a dense composite modified asphalt concrete upper surface layer, a dense composite modified asphalt concrete middle surface layer, a dense modified asphalt concrete anti-fatigue lower surface layer, a modified asphalt synchronous gravel sealing layer, an anti-cracking cement stabilized macadam base layer, an anti-cracking cement stabilized macadam subbase layer and a cushion layer which are sequentially arranged from top to bottom. Modified emulsified asphalt bonding layers are arranged among the upper surface layer, the middle surface layer and the lower surface layer; a common emulsified asphalt permeable layer is arranged between the synchronous gravel sealing layer and the base layer; the purpose of the invention is to enhance the adhesion between the structural layers of the pavement and ensure the shear resistance of the structural layers of the pavement.
本发明公开一种低温抗裂型复合改性沥青路面结构，涉及沥青混凝土路面技术领域，解决了缺少一种能够在不影响基层与沥青面层之间的粘结效果以及施工难度低的基础上，能够减少沥青路面在低温环境下产生温缩开裂的沥青路面结构的技术问题，本发明包括自上而下依次设置的密实型复合改性沥青混凝土上面层、密级配复合改性沥青混凝土中面层、密级配改性沥青混凝土抗疲劳下面层、改性沥青同步碎石封层、抗开裂型水泥稳定碎石基层、抗开裂型水泥稳定碎石底基层以及垫层；上面层、中面层以及下面层之间均设置有改性乳化沥青粘结层；同步碎石封层与基层之间设置有普通乳化沥青透层；其目的在于增强路面各结构层之间的粘结，保证路面结构层的抗剪能力。
