Abstract

The invention discloses modified asphalt prepared from waste packing tapes. The modified asphalt is prepared from a matrix asphalt material and a waste packing tape modifier in the mass ratio being (100:2)-(100:8). The invention also discloses a preparation method of the modified asphalt prepared from the waste packing tapes. The preparation method has the characteristics that the method is simpleto operate and low in cost, has no complex processing procedures and can be popularized in industrial production easily and the like. The prepared modified asphalt has better high-temperature anti-rut performance, the pavement performance of the asphalt is improved, a way is provided for recycling of the waste packing tapes, and the modified asphalt has remarkable environmental, social and economic benefits and wide application prospects.

Description

technical field [0001] The invention belongs to the field of road engineering, and in particular relates to a modified asphalt prepared by using waste sealing tape and a preparation method thereof. technical background [0002] In recent years, with the rapid development of e-commerce, the express delivery industry has become one of the fastest growing emerging industries. As a result, a huge amount of express packaging waste has also been generated. Moreover, the phenomenon of "excessive packaging" is serious in the express delivery industry. According to statistics, in 2016, the use of tape in the express delivery industry alone reached about 330 million rolls. If these waste tapes cannot be properly disposed of, it will seriously pollute the environment. It also causes waste of resources. As the country attaches great importance to the concept of green development, the resource recycling of waste tapes has attracted more and more attention. [0003] The waste sealing t...
