Normal-temperature asphalt modifier, modified asphalt and asphalt concrete
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.
