Embodiment 1
[0035] A kind of ecological garden landscape permeable road, such as figure 1 As shown, including the permeable road body, the two sides of the permeable road body are provided with curbs 1 along its length direction, and each curb 1 is provided with a water delivery tank 2 along the length direction of the permeable road body, and the end of the water delivery tank 2 is provided with The sump, the top of the water tank 2 is provided with a filter screen 7;
[0036] The permeable road body includes a permeable asphalt surface layer 3, a graded gravel base layer 4, an aquifer layer 5, and a rammed earth layer 6 arranged in sequence from top to bottom; the top surface of the permeable asphalt surface layer 3 is an upwardly convex arc surface, The angle between the tangent line passing through the two ends of the arc surface and the horizontal plane is 3-5°, here you can choose 3°, 4° or 5°, so that the arc surface maintains a certain upward convex arc, which is conducive to the ...
Embodiment 2
[0042] The permeable asphalt surface layer 3 material in Example 1 is made of the following components in parts by weight: 5 parts of AH-70 heavy traffic asphalt, 1 part of modified SBS, 90 parts of coarse aggregate, 8 parts of fine aggregate, mineral powder 5 parts, 1 part of polysiloxane, 0.5 part of antioxidant 1010;
[0043] Among them, the particle size of coarse aggregate is 2.36-16mm, and the particle size of fine aggregate is ≤2.36mm;
[0044] The preparation method of the permeable asphalt surface layer 3 material is as follows:
[0045] Step 1, mix dopamine methacrylamide and SBS at a molar ratio of 1:5 and dissolve in acetone, then add azobisisobutyronitrile, and react at 60°C for 2 hours, remove acetone after the reaction, and obtain the modified Sexual SBS;
[0046] Wherein, the mass ratio of azobisisobutyronitrile to dopamine methacrylamide is 1:15;
[0047] Step 2, take by weight 5 parts of AH-70 heavy traffic asphalt, 1 part of modified SBS, 90 parts of coar...
Embodiment 3
[0051] The material of the permeable asphalt surface layer 3 in Example 1 is made of the following components in parts by weight: 8 parts of AH-70 heavy traffic asphalt, 1.5 parts of modified SBS, 100 parts of coarse aggregate, 10 parts of fine aggregate, ore 4 parts of powder, 2 parts of polysiloxane, 1 part of antioxidant 1010;
[0052] Among them, the particle size of the coarse aggregate is 2.36-16mm, and the particle size of the fine aggregate is ≤2.36mm.
[0053] The preparation method is the same as that of Example 2, except that the formula of Example 2 is replaced with that of Example 3.
