Pavement expansion-joint filler made of red mud
The invention discloses a pavement expansion-joint filler made of red mud. The filler is made of red mud, chloroprene rubber, polymethyl methacrylate, sodium dodecyl sulfate, hydroxypropyl methyl cellulose, and redispersable latex powder. Through the cooperation between red mud and other components, the physical mechanical properties of the expansion-joint filler are enhanced and improved, the rebound value is increased, the redispersable latex powder can increase the binding performance and cohesive strength among molecules, thus the flexibility of the expansion-joint filler is strengthened, at the same time, the expansion-joint filler has an excellent performance on resisting water and alkali; the expansion-joint filler has the advantages of elasticity, viscosity, durability, and weatherability, can sustain long-term stretching, compressing and vibration, has a strong binding force, and can tolerate the repeated stretching and compressing due to the heat expansion and cold contraction happening in the joints, at the same time, the wastes are converted into valuable resources, the economic cost is reduced, and the problems of environment pollution and land wasting due to red mud stacking are solved.
