Abstract

A method for paving a steel bridge deck comprises laying consecutively a 0.6 mm-0.8 mm epoxy waterproofing bond material layer, a 30 mm-40 mm injectable self-flowing asphalt concrete material layer, a 0.4 mm-0.6 mm epoxy asphalt bond material layer, and a 25 mm-40 mm latex cement mortar poured asphalt concrete material layer onto the top of the steel bridge deck to form the steel bridge deck pavement structure.

First claim

What is claimed is:

1. A method for paving a steel bridge deck pavement structure comprising
laying consecutively a 0.6 mm-0.8 mm epoxy waterproofing bond material layer, a 30 mm-40 mm injectable self-flowing asphalt concrete material layer, a 0.4 mm-0.6 mm epoxy asphalt bond material layer, and a 25 mm-40 mm latex cement mortar poured asphalt concrete material layer onto the top of the steel bridge deck to form the steel bridge deck pavement structure; wherein,
the epoxy resin waterproof bond material layer is formed by mixing an epoxy resin of 1,6-hexanediol diglycidyl ether with a curing agent containing 2-acrylic acid and 1,3-butadiene polymer, in a weight mixing ratio of 50:50;
the injectable self-flowing asphalt concrete material layer is formed by mixing a binder with an aggregate, in a weight mixing ratio of 6-10:100; wherein the binder is composed of styrene-butadiene-styrene (SBS) copolymer modified asphalt, thermoplastic rubber, adhesive resin, and plasticizer, in a weight ratio of 100:10:2:1;
the epoxy asphalt bond material layer is composed of an epoxy resin of 1,6-hexanediol diglycidyl ether and a curing agent containing 2-acrylic acid and 1,3-butadiene polymer, in a weight mixing ratio of 50:50;
the latex cement mortar poured asphalt concrete material layer is composed of a macropore open-graded asphalt mixture and a latex cement mortar; wherein the macropore open-graded asphalt mixture is formed by mixing an asphalt binder with aggregates, in a weight mixing ratio of 4-8:100, the air-void content of the macropore open-graded asphalt mixture is 25-35%; the latex cement mortar poured asphalt concrete material layer is composed of a latex modifier, cement, standard sand and water, in a weight mixing ratio of 6:100:20:60; the latex cement mortar is impregnated into the macropore open-graded asphalt mixture through the pores of the macropore-opened asphalt mixture with an air-void content of 25˜35%.
