Example Embodiment
[0031] Example 1:
[0032] The ratio of various raw materials in this embodiment is as follows:
[0033] Table 1
[0034] name
[0035] Coupling agent (aluminate)
[0036] The asphalt in Table 1 is made by mixing 100# and 10# petroleum asphalt at a ratio of 5:1 to adjust the softening point and ductility of the asphalt.
[0037] Production is carried out according to the raw material ratio in Table 1. The specific steps are as follows:
[0038] First, put the softener low volatile aromatic oil into the reactor, heat the low volatile aromatic oil to 170-200°C, and put the modified material styrene-butadiene-styrene block copolymer (SBS) and poly Propylene (PP) is stirred and dispersed evenly, the speed of the stirring head is 100~200r / min, and the stirring time is 1~2 hours;
[0039] Then, put the asphalt and rubber powder into the reactor and stir and disperse evenly, the rotating speed of the stirring head is 100-200r / min, and the stirring time is 1-2 hours to obtain the intermed...

[0042] Example 2:
[0043] The ratio of various raw materials in this embodiment is as follows:
[0044] Table 2
[0045] name
[0046] Coupling agent (silane coupling agent)
[0047] The asphalt in Table 2 is made by mixing 100# and 10# petroleum asphalt in a 4:1 ratio to adjust the softening point and ductility of the asphalt.
[0048] Production is carried out according to the raw material ratio in Table 2, and the specific steps are the same as in Example 1.
Example Embodiment
[0058] Example 3:
[0059] The ratio of various raw materials in this embodiment is as follows:
[0060] Table 6
[0061] name
[0062] Softener (low volatile naphthenic oil)
[0063] The asphalt in Table 6 is made by mixing 100# and 10# petroleum asphalt in a ratio of 4.2:1 to adjust the softening point and ductility of the asphalt.
[0064] The production is carried out according to the raw material ratio in Table 6, and the specific steps are the same as in Example 1.
