Embodiment 1

[0029] In this embodiment, the preparation method of epoxy asphalt for steel bridge deck paving is as follows:

[0030] 1) According to parts by weight, weigh 6 parts of allyl bisphenol A epoxy resin, 4 parts of modifier, and 90 parts of petroleum-based asphalt; the modifier, in parts by weight, includes: nitrile rubber 36 parts, 42nm nano zinc oxide (ZnO) 4 parts, tetramethylthiuram disulfide (TMTD) 16 parts, sulfur (S) 60 parts, polyamide 40 parts;

[0031] 2) Heat the petroleum-based asphalt to 175°C and keep it warm while stirring at a slow speed (40r / min) and wait for the next process;

[0032] 3) Add the weighed allyl bisphenol A epoxy resin to the petroleum-based asphalt, and first stir slowly (40r / min) for 7 minutes to obtain mixture A;

[0033] 4) Add the weighed modifier to the mixture A, stir slowly (40r / min) and develop for 1.5h, and obtain epoxy asphalt for steel bridge deck paving after cooling.

Abstract

The invention relates to epoxy asphalt for steel bridge deck pavement and a preparation method thereof. The epoxy asphalt comprises, by weight, 4-16 parts of epoxy resin, 5-20 parts of a modifier and90 -100 parts of asphalt. The modifier comprises, in parts by weight, 20-40 parts of rubber, 4-8 parts of nanometer zinc oxide (ZnO), 10-25 parts of tetramethylthiuram disulfide (TMTD), 40-70 parts ofsulfur (S) and 24-46 parts of polyamide. The toughness of the modified epoxy asphalt for steel bridge deck pavement is significantly enhanced.

Description

Technical field [0001] The present invention relates to the technical field of asphalt, and more specifically, the present invention relates to an epoxy asphalt for paving steel bridge decks. Background technique [0002] Since the 21st century, my country’s economy has developed rapidly, traffic demand and total highway mileage have increased rapidly year by year, expressways have risen rapidly, and the proportion of domestic high-grade highways has also increased significantly. At the same time, great success has been achieved in the depth of highway access. Reached the countrywide village highway. In addition, urban development has increased the demand for large interchanges, viaducts and bridges. Asphalt pavement is the most used for high-grade pavement and bridge deck paving in my country, but ordinary asphalt pavement is difficult to meet the requirements of modern traffic, which restricts the development of road construction in China. Therefore, various modified asphalts ...
