High-performance wide-temperature-range epoxy asphalt concrete full-width paving construction method

Abstract

The invention discloses a high-performance wide-temperature-range epoxy asphalt concrete full-width paving construction method which comprises the following specific steps: (1) preparing epoxy asphaltconcrete; (2) carrying out epoxy zinc-rich paint spraying; (3) carrying out constant-temperature control on epoxy resin; (4) stirring the epoxy resin; (5) brushing the epoxy resin waterproof bondinglayer; (6) adding an epoxy resin binder; (7) paving the epoxy asphalt concrete in a full-width paving manner; (8) automatically scraping the epoxy asphalt concrete which does not flow on the side wallof the screed plate behind the spiral material distribution groove of the paver; (9) guiding rolling compaction on the paved epoxy asphalt concrete by adopting an intelligent rolling compaction mode;(10) detecting the thickness of a bridge deck pavement layer in a monitoring mode; and (11) detecting the quality and the service life of the pavement layer in a monitoring mode and a pavement layerearly-stage defect early-warning monitoring mode. The problem that traditional epoxy asphalt concrete is low in mechanization and intelligence degree is solved.

Description

technical field [0001] The invention relates to the technical field of bridge deck pavement, in particular to a construction method for full-width paving of epoxy asphalt concrete with high performance and wide temperature range. Background technique [0002] With the development of long-span steel bridge construction in China, a variety of bridge deck pavement materials have been applied, among which three pavement schemes of modified asphalt SMA, cast asphalt concrete and epoxy asphalt concrete are widely used. According to statistics In my country, epoxy asphalt concrete is used as the bridge deck pavement design scheme for the largest number of bridges, and it has been applied in the long-span steel bridge deck pavement of Runyang Bridge, Hangzhou Bay Bridge, and Zhanjiang Bay Bridge. However, epoxy asphalt concrete pavement has the following main problems: [0003] First of all, the traditional construction of epoxy asphalt concrete adopts separate lanes or sections and...
