Embodiment Construction

[0039] In order to facilitate the understanding of the structure of the present invention, the following description will be made in conjunction with the accompanying drawings and embodiments.

[0040] refer to figure 1 , is a schematic cross-sectional structure diagram of the stone pavement filling structure of the present invention, as figure 1 As shown, the present invention firstly provides a stone pavement filling structure. There are gaps between the stone pavement 9. The filling structure includes: a leveling layer 1 poured into the bottom of the gap; a flexible buffer layer 2 poured into the leveling layer 1 ; The filling layer 3 is poured on the flexible buffer layer 2 until the top of the gap.

[0041] Specifically, the leveling layer 1 includes cement slurry, preferably Portland cement as the cement slurry with a thickness of 2 cm, the flexible buffer layer 2 includes asphalt, preferably block dry asphalt with a thickness of 5 cm, and the filling layer 3 is a cemen...

Abstract

The invention provides a gap filling structure and construction method for a stone road surface. The stone road surface has a gap. The gap filling structure comprises a leveling layer, a flexible buffering layer, and a filled layer, wherein the leveling layer is poured to the bottom of the gap; the flexible buffering layer is poured on the leveling layer; the filled layer is poured on flexible resins until the top of the gap. The gap filling structure disclosed by the invention solves the problems that a conventional gap filling manner is poor in waterproof effect, poor in loading capability and the like, and the efficiency and the quality of gap filling construction are further improved.

Description

technical field [0001] The invention relates to a pavement filling structure and a construction method thereof, in particular to a filling structure and a construction method suitable for filling the gaps generated during the stone pavement pavement of a motorway. Background technique [0002] At present, stone pavement is often used more in square pavement. The existing treatment method for pavement gaps is pouring cement mortar. However, this treatment method can only achieve a simple waterproof effect, and cannot transmit horizontal loads between stone materials. As time goes by, the long-term effect of horizontal loads will be Make the waterproof effect worse and worse. [0003] If the stone pavement of the motorway is treated according to the joint filling process of square stone, after the road is opened to traffic, the large horizontal load generated by a large number of vehicles will squeeze the gap, and the cement mortar joint filler will be destroyed, so that the ...
