Example Embodiment
[0017] Example 1:
[0018] A wide-area modified asphalt, (1) uses 91 grams of 130-140℃ hot asphalt as the main raw material; (2) uses 4 grams of powdered styrene butadiene rubber as the first modifier; (3) Using 5 grams of polyethylene wax as the second modifier, the above-mentioned components are mixed to form a wide-area modified asphalt.
[0019] The preparation method of this wide-area modified asphalt is as follows:
[0020] 1) Add 4 grams of powdered styrene-butadiene rubber to 91 grams of hot asphalt at 130-140°C, and shear it to produce high extension modified asphalt;
[0021] 2) Add 5 grams of polyethylene wax to the high elongation modified bitumen, and stir to make a wide area modified bitumen.
Example Embodiment
[0022] Example 2:
[0023] A wide-area modified asphalt, (1) uses 95 grams of 130-140℃ hot asphalt as the main raw material; (2) uses 2 grams of powdered styrene butadiene rubber as the first modifier; (3) Using 3 grams of polyethylene wax as the second modifier, the above-mentioned components are mixed to make a wide-area modified asphalt.
[0024] The preparation method of this wide-area modified asphalt is as follows:
[0025] 1) Add 2 grams of powdered styrene-butadiene rubber to 95 grams of hot asphalt at 130-140°C and shear it to produce high-extension modified asphalt;
[0026] 2) Add 3 grams of polyethylene wax to the high elongation modified asphalt, and mix it to make a wide area modified asphalt.
Example Embodiment
[0027] Example 3:
[0028] A wide-area modified asphalt, (1) uses 92 grams of 130-140℃ hot asphalt as the main raw material; (2) uses 3.5 grams of powdered styrene butadiene rubber as the first modifier; (3) 4.5 grams of polyethylene wax is used as the second modifier, and the above-mentioned components are mixed to form a wide-area modified asphalt.
[0029] The preparation method of this wide-area modified asphalt is as follows:
[0030] 1) Add 3.5 grams of powdered styrene-butadiene rubber to 92 grams of hot asphalt at 130-140°C, and shear it to produce high extension modified asphalt;
[0031] 2) Add 4.5 grams of polyethylene wax to the high elongation modified bitumen, and stir to make a wide area modified bitumen.
