Abstract

The invention discloses an anti-skid shock-absorbing pavement which is formed by pouring concrete. The concrete is prepared from a gel material, cement, mineral powder, coal ash, a fine aggregate, anelastic agent, magnesium silicate, modified light calcium powder, methyl acrylate, titanium dioxide, glass fibers, cotton fibers, triethanolamine, polyimide, sodium dodecyl benzene sulfonate and water. The elastic agent is elastic particles, the granularity of which is 0.02-0.006 mm, the grade of the mineral powder is S95, the fineness modulus of the fine aggregate is 2.3-2.8, the apparent densityis greater than 2300 kg / m<3>, and the bulk density is greater than 1200 kg / m<3>. The concrete is simple in formula and shrinkage cracks of bridge concrete can be prevented effectively. By doping theelastic agent into the bridge concrete, the bridge pavement is shock-absorbing and is wear-resistant, and the durability of the bridge construction can be improved. The impact loss ability of the concrete is improved greatly, and the service life of the concrete is prolonged.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to an anti-slip and shock-absorbing bridge pavement. Background technique [0002] Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades; these characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal Engineering, etc.; in recent years, with the continuous construction of super high-rise buildings in my country, the height of super high-rise buildings has been continuously refreshed, the stress state of the foundation floor has been aggravated, the structure has become thicker, and the requirements for concrete strength grades have become higher and higher. The amount of cement...
