Bridge deck pavement block, bridge paved by same and manufacturing method of bridge deck pavement block

Abstract

The invention discloses a bridge deck pavement block, a bridge paved by the same and a manufacturing method of the bridge deck pavement block. The bridge deck pavement block comprises a pavement block body which is composed of composite rubber concrete or rubber asphalt concrete. Compared with the prior art, the bridge deck pavement block has the advantages that the pavement block body made by the composite rubber concrete or the rubber asphalt concrete is adopted, so that mechanical performance, high-temperature stability, water stability, low-temperature cracking resistance, anti-aging performance and deforming resistance are all improved substantially compared with conventional bridge deck pavement structures, the bridge deck pavement block is light in weight, long in service life and resistant to fatigue and cracking, the problem that current bridge deck pavement structures are prone to various problems like sliding, pushing, cracking, pitting, rutting and bumping, and the bridge deck pavement block is suitable for pavement of various hard bridge decks; the pavement block body is prepared by compositing reclaimed rubber and stone, so that the bridge deck pavement block is low in cost, high in elasticity and excellent in damping performance.

Description

technical field

[0001] The invention relates to a bridge deck paving block and a processing method of the paving block, and also relates to a bridge covered with the paving block. Background technique

[0002] Steel bridges are beneficial to reduce dead loads and give full play to the characteristics of space structures, and are the preferred structural form of long-span bridges. However, the characteristics of steel bridge decks such as smoothness, flexibility, large local deformation, complex dynamic characteristics, and small heat capacity all put forward strict requirements for bridge deck pavement. Existing steel bridge deck pavements, regardless of cast asphalt concrete (GA), asphalt mastic concrete (MA), modified asphalt (SMA), epoxy resin asphalt (EA), all have premature high-temperature rutting, lateral movement, and cracking These diseases are not only related to the unfavorable use conditions of steel bridge deck pavement, but also directly related to the traffic ...
