High-temperature-resistant composite modified asphalt for roads and preparation method thereof

Abstract

The invention discloses high-temperature-resistant composite modified asphalt for roads and a preparation method of the high-temperature-resistant composite modified asphalt. The material is preparedfrom the following raw material components: n-hexylamine, a functional polymer, activated waste glass powder, styrene, divinylbenzene, epoxy asphalt, dithiothreitol, zinc nitrate hexahydrate, potassium persulfate, sodium citrate, epoxy resin, an aminoalkyl silane coupling agent, an epoxy silane coupling agent, a chain extender, carboxyl silicone oil, mineral fiber, an antioxidant and aggregate. The waste glass powder has low heat conductivity coefficient and high thermal insulation performance, and the waste glass powder is added into the asphalt mixture, so that waste resources can be reasonably utilized, the environmental pressure is reduced, the resistance of the asphalt pavement to heat can be effectively improved, and the service life of the asphalt pavement is prolonged.

Description

technical field

[0001] The invention relates to the technical field of asphalt, in particular to a high-temperature-resistant composite modified asphalt for roads and a preparation method thereof. Background technique

[0002] Asphalt is an organic gel material with waterproof and anti-corrosion properties, which is widely used in coatings, plastics, rubber engineering, etc. The asphalt mixture obtained by mixing asphalt, mineral fiber, aggregate and other materials can also be used to pave roads; compared with ordinary cement pavement, the road paved with asphalt mixture has a smoother and smoother surface, more comfortable driving experience and better safety performance. High, so very favored by engineers and people.

[0003] However, the traditional asphalt pavement generally has the problem of insufficient high temperature resistance, and it is easy to change the structure due to changes in the ambient temperature, especially in the hot summer, when the temperature ris...
