Abstract

The invention provides a normal-temperature asphalt modifier, modified asphalt and asphalt concrete. The normal-temperature asphalt modifier is a mixture containing waste engine oil, rubber tires and plastic extract. The normal-temperature asphalt modifier is added to matrix asphalt at the temperature of 130 DEG C-150 DEG C, and the mixture is stirred, so that the modified asphalt is obtained. The asphalt concrete comprises the modified asphalt and mineral aggregates. The normal-temperature asphalt modifier utilizes three or more high-molecular polymers including the waste engine oil, the rubber tires, the plastic extract and the like, and the three or more high-molecular polymers are blended to form a polymer alloy with an interpenetrating polymer network. A storable road normal-temperature asphalt modifier can be obtained by the asphalt modified by the normal-temperature asphalt modifier. The asphalt concentrate has the advantages of low carbon, energy saving, environment protection, availability in case of pavement, little repair, low construction cost, good adaptability, long service life, convenience in construction, health and low station construction cost.

Description

technical field [0001] The invention relates to the technical field of asphalt modifiers, in particular to normal-temperature asphalt modifiers, normal-temperature modified asphalt and warm-mixed and cold-paved asphalt concrete. Background technique [0002] With the rapid growth of the national economy, my country's highway construction has entered a good development period. The achievements of expressway construction are astounding, but the problem of damage to asphalt concrete pavement is more and more common. The existing conventional means to improve the road performance of asphalt is to add asphalt modifier to asphalt or asphalt concrete, and the asphalt modifier can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt. [0003] Most of the current asphalt modifiers use natural or synthetic organic or inorganic materials. Although they have a certain effect on improving the use effect of asphalt pavement, there is no breakthrough pro...
