Asphalt pavement structure capable of preventing crack propagation and construction method

LU LIN

The invention relates to an asphalt pavement structure for preventing crack propagation and a construction method. The asphalt pavement structure comprises a base layer, an old surface layer arranged on the base layer and a new surface layer arranged on the old surface layer, an I-shaped groove from the gap on the old surface layer to the base layer is formed, and a gap stopping structure in the I-shaped groove is arranged. the old surface layer is provided with a connecting hole used for being connected with a seam stopping structure; a connecting rod is arranged in the connecting hole; an anti-upheaval device is arranged between the old surface layer and the new surface layer. According to the invention, the seam stopping structure is arranged at the slot, so that the problem of upward reflection through the crack is effectively solved; an anti-upheaval device is arranged to effectively relieve the generation of upheaval diseases of a new surface layer; the base layer, the seam stopping structure and the old surface layer are connected into a whole through the arranged connecting rods, the integrity and strength of the pavement structure are enhanced, and it is guaranteed that the pavement structure is not prone to damage.

本发明涉及一种防止裂缝扩展的沥青路面结构及施工方法。所述沥青路面结构包括基层，在基层上设置的旧面层，以及在旧面层上设置的新面层；在所述旧面层上的缝隙处开槽至基层中形成工形槽，在工形槽中设置止缝结构；在所述旧面层上开设有用于连接止缝结构的连接孔；所述连接孔中设置有连接杆；在所述旧面层和新面层之间设置有抗拥包装置。本发明通过在缝隙处开槽设置止缝结构，有效解决贯穿裂缝向上反射的问题；设置的抗拥包装置有效缓解新面层拥包病害的产生；设置的连接杆将基层、止缝结构和旧面层连接为整体，增强路面结构的整体性和强度，保证路面结构不易损坏。
