Embodiment 1

[0035] (1) Material preparation: After dehydration and air-drying, the ceramic polishing waste and waste powder from ceramic enterprises are sent to a ball mill to be ground into powder, and then sent to a special ash storage tank for standby.

[0036] (2) Ingredients: Surface-modified ceramic polished brick powder Ingredients: The mass ratio of ceramic polished brick powder to silane coupling agent KH-550 solution with a mass concentration of 1% is 1:1; The mass percentages are as follows: surface-modified ceramic polished brick powder 5%, ordinary road petroleum asphalt 95%.

[0037] (3) Prepare deionized ethanol solution: mix deionized water and dehydrated ethanol, and adjust the pH value of the mixed solution with glacial acetic acid, wherein the ratio of each raw material is: m (deionized water): m (dehydrated ethanol)= (1~4): (6~9), pH=3~5, the mixed solution is obtained;

[0038] (4) Preparation of silane coupling agent KH-550 solution: Weigh a certain amount of silane...

Embodiment 2

[0042] Example 2: surface-modified ceramic polished brick powder ingredients: the mass ratio of ceramic polished brick powder and silane coupling agent KH-550 solution with a mass concentration of 2% is 1:1; the proportion of modified asphalt raw materials accounts for the mass The percentages are as follows: surface modified ceramic polished brick powder 8%, ordinary road petroleum asphalt 92%. Others are the same as in Example 1. The main technical indicators of the above-mentioned modified asphalt are as follows: penetration 63.4, ductility at 25°C > 100, softening point 51.4, residual penetration ratio 72.6, residual ductility 11.2, and the adhesion level to coarse aggregate is 5 .

Embodiment 3

[0043] Example 3: Surface-modified ceramic polished brick powder ingredients: the mass ratio of ceramic polished brick powder to 3% silane coupling agent KH-550 solution is 1:2; the ratio of modified asphalt raw materials accounts for the mass The percentages are as follows: surface modified ceramic polished brick powder 10%, ordinary road petroleum asphalt 90%. Others are the same as in Example 1. The main technical indicators of the above-mentioned modified asphalt are as follows: penetration 62, ductility at 25°C > 100, softening point 52.0, residual penetration ratio 70.3, residual ductility 10.4, and adhesion to coarse aggregate grade 5 .

Abstract

The invention discloses ceramic-polished-tile-powder-modified asphalt made from industrial waste residue and a preparation method of modified asphalt. The method comprises drying ceramic polished waste residue, performing grinding and screening to obtain ceramic polished tile powder, performing surface modification to the ceramic polished tile powder with a silane coupling agent solution to obtainsurface-modified ceramic polished tile powder, mixing the surface-modified ceramic polished tile powder with common road asphalt, and performing heating melting, shearing stirring and delaying curingto make modified asphalt. Compared with common road asphalt, the modified asphalt has no obvious change in penetration, ductility and softening point, while has improved adhesion performance with aggregates, and is obviously improved in residual penetration and residual ductility, so that the road performance is obviously improved. Ceramic industrial solid waste is fully utilized, and pollution of the waste to the environment is greatly reduced. The preparation method is simple in process, stable in product quality, can be widely applied to laying of multiple grades of roads and building waterproofness, and has great economic benefit and social benefit.

Description

technical field [0001] The invention relates to a building material, in particular to a ceramic polished brick powder modified asphalt using industrial waste residue and a preparation method thereof. Background technique [0002] At present, more than 98% of the expressways in our country have adopted asphalt pavement. However, with the increase of vehicle flow, heavy axle load and excessive speed, the pavement structure is seriously damaged, which puts higher demands on the quality of asphalt pavement. requirements. Modified asphalt is a functional high-grade pavement material. It combines the dual advantages of asphalt and modifiers. It is superior to ordinary road petroleum asphalt and can be used for high-grade pavement. It is a promising new material in the 21st century. Polymer-modified asphalt has become the mainstream of asphalt modification because it can effectively enhance the disease resistance of asphalt pavement, but it is expensive, difficult to process, and ...
