example 1

[0024] Take the rice husk and wash it, dry it naturally and place it in a tube-type atmosphere furnace at 125 °C for 25 min, then pass nitrogen to remove the air, control the nitrogen flow rate to 100 mL / min, and raise the temperature to 450 °C at a rate of 5 °C / min under nitrogen protection. ℃, after heat preservation and carbonization for 1 h, let it stand and cool to room temperature to obtain carbonized rice husks, weigh 45 parts of carbonized rice husks, 10 parts of sodium fluoride and 15 parts of nano-iron powder, stir and mix them, and place them in graphite In the crucible, place the graphite crucible at 1250°C under an argon atmosphere for sintering treatment for 3 hours. After the sintering is completed, stop feeding argon gas and naturally cool to 650°C. After oxidation treatment for 5 hours, naturally cool to room temperature to obtain the modified material ; In parts by weight, weigh 45 parts of kaolin powder, 10 parts of aluminum sulfate and 15 parts of sodium sul...

Abstract

The invention discloses an antiskid modified bridge deck paving material and a preparation method thereof, which belongs to the field of building materials. The preparation method comprises the following steps: by counting in parts by weight, respectively weighing epoxy resin, dispersed curing liquid, silicate cement, stone particles, polycarboxylic acid water reducer and rubber particles, stirring, mixing, then laying the mixture on a bridge deck after the stirring and the mixing are finished, standing, curing, and naturally maintaining, thus obtaining the antiskid modified bridge deck paving material. The antiskid modified bridge deck paving material has the beneficial effects that the friction coefficient is large, and the corrosion resistance is good (chemical stability is good), and the paving material has relatively good antiskid performance and durability and is worth of being popularized to use.

Description

technical field [0001] The invention relates to an anti-slip modified bridge deck pavement material and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Bridges are the throats of transportation, and their mileage accounts for a small proportion of the total mileage of highways, but their maintenance has a huge impact on the traffic capacity of the entire road network. Due to the special structural location of the bridge deck pavement, its service life is much shorter than that of ordinary asphalt pavement. Since it is easier to form channelized traffic at the bridge, and the pavement is more complex in stress, the bridge deck pavement is more prone to early damage than ordinary asphalt pavement, which seriously restricts its service quality and life. Frequent maintenance, repairs, and even renovations not only waste a lot of financial, material and manpower, but also cause serious traffic congestion. [0003] Bridge...
