Embodiment 1
[0043] The warm-mix type anti-rutting composite modifier described in this embodiment is composed of the following raw materials in terms of the following mass percentages:
[0044] Special warm mix agent: 3wt%; Wherein, in the said special warm mix agent, in terms of mass percentage, include 30wt% sodium perfluorooctane sulfonate, 30wt% dodecyl glucoside, 40wt% caralamide ;
[0045] Powdered solids: 68wt%;
[0046] Polyethylene wax: 7 wt%;
[0047] Sulfur: 7 wt%;
[0048] Hard asphalt: 15wt%.
[0049] In this example, the powdery solids are obtained from oily sludge (in which the oil content is 90wt%, and the solid content is 5wt%) through the thermal extraction and dehydration process of oily sludge. The process is as follows: send the oily sludge into the centrifuge, and simultaneously The flocculant, that is, polyacrylamide, is added to the centrifuge. The amount of the flocculant added is such that the final powdery solid contains 0.03wt% flocculant. After the oily sl...
Embodiment 2
[0053] The warm-mix type anti-rutting composite modifier described in this embodiment is composed of the following raw materials in terms of the following mass percentages:
[0054] Special warm mix agent: 7.2wt%; Wherein, in the described special warm mix agent, by mass percentage, include the sodium perfluorooctane sulfonate of 32wt%, the alkyl glycoside of 42.6wt% ((C 6 h 11 o 6 ) n R, wherein R=C10, n=2), 25.4wt% carolamide;
[0055] Powdered solids: 38.3 wt%;
[0056] Polyethylene wax: 11.2 wt%;
[0057] Sulfur: 15 wt%;
[0058] Hard asphalt: 28.3wt%.
[0059] The preparation method of the powdery solids described in this example is as follows: send the oily sludge (in which the oil content is 69wt%, and the solid content is 24wt%) into the centrifuge, and at the same time add flocculant, namely oleic acid, to the centrifuge The amount of polyoxyethylene ester and flocculant added is such that the final powdery solid contains 0.05wt% flocculant, and the oily sludge...
Embodiment 3
[0063] The warm-mix type anti-rutting composite modifier described in this embodiment is composed of the following raw materials in terms of the following mass percentages:
[0064] Special warm mix agent: 3.6wt%; Wherein, in the described special warm mix agent, by mass percentage, include the sodium perfluorooctane sulfonate of 43.8wt%, the lauryl glucoside of 31wt% ((C 6 h 11 o 6 ) n R, wherein R=C8 alkyl, n=1), 30wt% carolamide;
[0065] Powdery solids: 38wt%; among them, the inorganic components in the powdery solids account for 70wt%, and the organic components account for 30wt%;
[0066] Polyethylene wax: 18.1wt%;
[0067] Sulfur: 19wt%;
[0068] Hard asphalt: 21.3wt%.
[0069] The preparation method of powdery solid described in the present embodiment is as follows:
[0070] The oily sludge (in which the oil content is 43wt%, and the solid content is 48wt%) is sent into the centrifuge, and at the same time, a flocculant, namely a mixture of cocamidopropyl betain...
