Pavement seal coat structure and construction method
The invention relates to the field of asphalt pavements, and particularly discloses a pavement seal coat structure and a construction method. The pavement seal coat structure comprises an SMA thin overlay, a geogrid and a stress absorption layer which are sequentially arranged from top to bottom, and the stress absorption layer comprises SBS modified emulsified asphalt and glass fibers; the geogrid comprises a plurality of transverse grid bars and a plurality of longitudinal grid bars, the longitudinal grid bars are arranged on the lower sides of the transverse grid bars, connecting pieces are arranged at the crossed joints of the transverse grid bars and the longitudinal grid bars, transverse steel bars are arranged in the transverse grid bars, and the transverse steel bars are connected with a plurality of fastening steel bars penetrating out of the transverse grid bars at intervals. The longitudinal grid bars are provided with through holes allowing the fastening steel bars to penetrate through, two longitudinal steel bars are arranged in each longitudinal grid bar, and the through holes are formed between the two longitudinal steel bars. The advantages of the SMA thin overlay, the geogrid and the stress absorption layer are combined, the interlayer bonding performance is excellent, the pavement performance is improved, and therefore the service life of a road is prolonged.
本申请涉及沥青路面的领域，具体公开了一种路面封层结构及施工方法。路面封层结构，包括由上至下依次设置的SMA薄层罩面、土工栅格和应力吸收层，应力吸收层包括SBS改性乳化沥青和玻璃纤维；土工栅格包括多个横向栅条和多个纵向栅条，纵向栅条设置于横向栅条下侧，横向栅条和纵向栅条的交叉连接处设置有连接件，横向栅条内部设置有横向钢筋，横向钢筋间隔连接有多个穿出横向栅条的紧固钢筋，纵向栅条设置有供紧固钢筋穿过的通孔，纵向栅条内部设置有两个纵向钢筋，通孔设置于两个纵向钢筋之间。本申请结合SMA薄层罩面、土工栅格和应力吸收层的优点，层间粘结性能优良，使得路面性能提高，从而延长道路的使用寿命。
