Problems solved by technology

[0003] In the prior art, the road performance of the asphalt pavement deteriorates rapidly due to the rutting, pushing, waves, and other diseases caused by the heavy load of the asphalt pavement, and the difficulty of construction is increased due to the insufficient viscosity of the asphalt during paving. The pavement paved by the existing technology is too hard and too weak, which reduces the durability of the pavement against deformation. In the prior art, increasing the amount of magnesium hydroxide added by adding a flame retardant will seriously affect the performance of the modified asphalt coating. High temperature resistance, low temperature bendability, mineral adhesion and glue bonding performance, and increase the cost, so there is an urgent need for a high viscosity improved asphalt to change the status quo

Abstract

The invention belongs to the technical field of asphalt materials and in particular relates to high-viscosity improved asphalt and a preparation process. The high-viscosity improved asphalt comprisesthe following components: 100-200 parts of natural asphalt, 150-200 parts of biological asphalt, 30-60 parts of a tackifying resin, 30-50 parts of rubber powder, 60-100 parts of packing, 40-70 parts of a stabilizer, 20-50 parts of a defoaming agent and 10-30 parts of a curing agent. The asphalt is prepared from the components through procedures such as mixing, stirring and defoaming. Compared withthe prior art, the high-viscosity improved asphalt has the beneficial effects that with the combination of rock asphalt with biomass heavy oil, the viscosity of the product provided by the inventioncan be improved through the tackifying resin and the rubber powder, and the asphalt is greatly improved when being compared with common asphalt; due to addition of the defoaming agent and the curing agent, bubbles inside the product can be reduced, and properties of the product can be improved; through steps of the invention, mixtures are firstly mixed at a high temperature, melting debubbling treatment is further carried out, the product provided by the invention has very large viscosity, and different properties of the asphalt can be all improved.

Description

technical field [0001] The invention belongs to the technical field of asphalt materials, and in particular relates to a high-viscosity improved asphalt and a preparation process. Background technique [0002] Natural asphalt is the residue of petroleum seeping out of the ground after long-term exposure and evaporation; the rapid development of highways urgently requires a large amount of high-quality asphalt materials, and most of the currently used asphalt is refined from crude oil, which is a non-renewable resource. Bio-asphalt not only It can solve the environmental problems caused by the disposal of a large amount of municipal and agricultural and forestry solid waste, and can also reduce pollution. It is a renewable resource, so how to make good use of bio-asphalt and natural asphalt in the research of asphalt materials is a problem worth studying. [0003] In the prior art, the road performance of the asphalt pavement deteriorates rapidly due to the rutting, pushing, ...
