preparation example Construction

[0034] The preparation process of the SBS modified asphalt is as follows: when the asphalt is heated to 120-150°C, the SBS modifier is added for stirring, and then heated continuously to 180-200°C to obtain the SBS modified asphalt. No. 90 asphalt is used. The addition amount of the SBS modifier is 5-9% of the asphalt mass.

[0035] This application selects fan waste with different particle sizes to replace aggregates in asphalt mastic gravel mixture: fan powder waste replaces crushed stones with a particle size of ≤0.075mm; Among the fiber waste, fan fiber waste is selected to replace lignin fiber as a stabilizer; fan block waste is used to replace gravel with a particle size > 9.5 mm.

[0036] The total amount of recycled fan blade waste accounts for 0.12% to 0.15% of the total mass of all materials.

[0037] The asphalt ratio of SBS modified asphalt and all materials is 5.00%-8.00%.

[0038] The present application also protects a preparation method of the above-mentioned...

Embodiment 1

[0043] In this embodiment, the asphalt mastic macadam mixture with recycled fan blade waste as filler, in parts by weight, includes the following components: 0.7kg of SBS modified asphalt, and the total mass of lignin fiber and fibrous waste is 0.8kg , crushed stone 10kg, fan powder waste 0.4kg, fan massive waste 0.2kg in total;

[0044] Fan powder waste replaces gravel with a particle size of ≤0.075mm; in the fiber waste with a particle size of >0.075mm and a particle size of ≤9.5mm, choose fan fiber waste to replace lignin fiber as a stabilizer; use fan block waste to replace Crushed stone with a particle size > 9.5mm.

[0045] The total amount of recycled fan blade waste accounts for 0.14% of the total mass of all materials.

[0046] The asphalt mastic macadam mixture adopts SMA-16 skeleton structure gradation,

[0047] The gradation of asphalt horseshoe grease mixture is as follows:

[0048] Mesh size(mm) 19 16 13.2 9.5 4.75 2.36 1.18 0.6 0.3 0.15 0....

Embodiment 2

[0055] The raw material selection and preparation method of the mixture in this example are the same as in Example 1, except that the mass ratio of lignin fiber and fan fiber waste added is 1:9.

Abstract

The invention relates to a stone mastic asphalt mixture using recycled fan blade waste as a filler. The mixture comprises the following components in parts by weight: 6-9 parts of SBS modified asphalt, 8-12 parts of lignin fibers and fan fibrous waste, 100-150 parts of crushed stones, 4-6 parts of fan powder waste and 1-5 parts of fan blocky waste. In the mixture, the particle size of the fan powder waste is smaller than 0.075 mm, the particle size of the fan fiber waste is larger than or equal to 0.075 mm and smaller than 9.5 mm, the length-width ratio of the fan fiber waste is larger than 10, the particle size of the fan block waste is greater than or equal to 9.5 mm, aggregate except asphalt in the stone mastic asphalt mixture meets the grading requirement of the national stone mastic asphalt mixture, and the SBS modified asphalt adopts No.90 matrix asphalt. By means of the size synergistic effect of the fan fiber waste materials of various sizes, the fan blade waste materials, thelignin fibers and the crushed stone aggregates form a better interlocking framework structure and dense filling in the stone mastic asphalt mixture, and the anti-cracking performance and the anti-rutting performance of the material are improved.

Description

technical field [0001] The invention relates to the field of material science and engineering, in particular to an asphalt mastic gravel mixture prepared by recycling fan blade waste and a preparation method thereof. Background technique [0002] Wind energy is a clean, renewable and efficient energy source. At present, wind power generation technology is used on a large scale around the world. As of 2018, the total installed capacity of wind power in the world is 539GW. The service life of fan blades is about 15 years, and the installed capacity of wind power is also increasing. Due to reasons such as reaching the service life and damage, a large number of fan blades will be decommissioned. In my country, 5,700 tons of fan blades were decommissioned in 2018, and 5,900 tons of fan blades will be decommissioned by 2022. A large number of decommissioned fan blades not only pollute the environment, but also lead to a waste of resources. At present, the main components of dec...
