Abstract

The invention discloses an environment-friendly cementing agent for road use. The environment-friendly cementing agent comprises the following components in parts by weight: 20-60 parts of waste plastic, 10-30 parts of rubber oil, 5-8 parts of waste butadiene styrene rubber powder, 2-8 parts of modified starch, 2-10 parts of lignin, 5-15 parts of inorganic filler and 1-5 parts of coupling agent. The invention also discloses a preparation method of the environment-friendly cementing agent for road use. The environment-friendly cementing agent for road use is good in high-temperature stability, has excellent low-temperature crack resistance and high cementing capability, has no production of excessive waste gas, waste water and solid wastes in a preparation process and is high in construction capability; in addition, the environment-friendly cementing agent for road use has the effect of turning wastes into valuables by taking the waste plastic and waste rubber as raw materials, so that not only are resources saved, but also the processing cost is also reduced.

Description

Technical field: [0001] The invention relates to the technical field of pavement mixtures, in particular to a binder for environment-friendly roads. Background technique: [0002] The rapid development of the economy has put forward high requirements for the transportation construction industry: the roads must extend in all directions, and be capable of high speed, heavy axle load, and large flow. Newly built roads require a large amount of asphalt as a binder, and maintenance is a long-term task, which puts forward eternal requirements for asphalt. Bitumen is derived from petroleum, which is a non-renewable resource with huge but limited reserves. [0003] In addition, with the development of the polymer material industry, the application of plastic products is becoming more and more extensive, and has become an indispensable part of people's life. The "white pollution" within the scope is not only a major public hazard of environmental protection, but also causes a huge ...
