Abstract

The invention discloses a road and bridge caulking asphalt. The road and bridge caulking asphalt comprises the following ingredients: a petroleum asphalt, a compatilizer, a stabilizer, an antioxidant,a flow modifier, a modified oxidized graphene, a modified bagasse molecular sieve, and SBS. The oxidized graphene and the bagasse molecular sieve are added, a net-shaped structure is formed in the inner part of the asphalt without crosslinking, the shock resistance effect is good; part of aluminum hydroxide and ferric oxide form a high-temperature-resistant high-stability hercynite structure at the high temperature, the high-temperature-resistant high-stability hercynite structure is adhered to the formed net-shaped structure, the structure is stabler, the high and low temperature resistanceproperty is better, the asphalt also has the functions of being waterproof, ultraviolet-proof and antiflaming at the same time; the bagasse molecular sieve is modified, so that the reaction effect isbetter in the subsequent process of reaction with the aluminum hydroxide. In conclusion, the road and bridge caulking asphalt can still be normally used for a long term even under the environment withthe limit difference of temperature.

Description

technical field [0001] The invention relates to the technical field of road surfaces, in particular to a road bridge caulking asphalt and a preparation method thereof. Background technique [0002] At present, road caulking and sealing materials have relatively mature technology and equipment abroad, and have also been widely used. The research and production of our caulking and sealing materials are still in the exploratory stage. Compared with foreign developed countries, the quality is far behind, and the production technology is far from mature. Generally, ordinary road asphalt is used, but the high and low temperature performance of ordinary road asphalt is poor. , easy to fall off, can not effectively prevent rainwater from leaking into the base from the joints and prevent debris such as sand and gravel from being embedded in the joints to cause the concrete panels to be crushed, which seriously affects the quality and service life of the road bridge deck. This is also...
