A kind of steel slag aggregate synchronous crushed stone seal layer material and construction method for highway maintenance

Abstract

The invention relates to a synchronous pavement surface dressing material for steel slag aggregate for road maintenance, and a construction method thereof. The synchronous pavement surface dressing material for steel slag aggregate is prepared from the following raw materials in percentage by weight: 85%-95%, 5-15 of asphalt, and 0-10% of paddings, wherein the paddings comprise the following components in parts by weight: 10-90 parts of limestone dust and 10-90 parts of semi-dry flue gas desulfurization ash. The synchronous pavement surface dressing material for steel slag aggregate has good water-proof, antiskid and wear-resistance properties. The synchronous pavement surface dressing material for steel slag aggregate provides an effective approach for the recycling of steel slag and desulfurization ash, in addition, the road construction cost is also lowered, and good economic and environment benefits can be achieved.

Description

technical field [0001] The invention belongs to the technical field of highway maintenance, and in particular relates to a steel slag aggregate synchronous crushed stone sealing layer material and a construction method for highway maintenance. Background technique [0002] Steel slag is the slag discharged during the steelmaking process and is the main solid by-product of the smelting industry. For a long time, a large amount of steel slag has been piled up, not only occupying a large area of ​​industrial and agricultural land, but also causing great pollution to the environment. With the development of the steel industry, the discharge of steel slag is also increasing year by year. How to strengthen the resource utilization of steel slag has become the key to the sustainable development of the steel industry and the protection of the ecological environment. [0003] Synchronous gravel sealer is to use a synchronized gravel sealer to sprinkle gravel and bonding materials on...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the problems in the prior art that steel slag is difficult to be harmlessly treated and utilized, and road maintenance relies heavily on high-quality stones, the present invention provides a steel slag aggregate synchronous crushed stone seal layer material and construction method for road maintenance , synchronous crushed stone seal material uses steel slag instead of stone, which reduces the impact of steel slag on the environment; and uses desulfurization ash to further reduce production costs
