Examples
Embodiment 1
[0026] Example 1 : A large-porosity epoxy asphalt macadam drainage base with drainage function is a mixture formed by uniform mixing at 110°C with epoxy asphalt as the binder and open-graded crushed stone as the aggregate. The mass ratio of epoxy asphalt to gravel is 3.0:100, and the design gradation of the aggregate is as follows:
[0027]
[0028] The laying process of the epoxy asphalt gravel drainage base as mentioned above is as follows: firstly, clean the surface of the subbase; secondly, evenly spray the epoxy asphalt waterproof bonding layer, according to 0.4Kg / m 2 thirdly, lay epoxy asphalt macadam drainage base, rolling and forming, pavement thickness is 6cm, and wait for the end of the age to construct the surface layer.
Embodiment 2
[0029] Example 2: The difference from Example 1 is that the mass ratio of epoxy asphalt to gravel is 4.0:100, and the epoxy asphalt waterproof bonding layer is laid according to 0.6Kg / m 2 The amount of spraying is controlled and the paving thickness is 10cm.
Embodiment 3
[0030] Example 3: A large-porosity epoxy asphalt macadam drainage base with drainage function is a mixture formed by uniform stirring at 110°C with epoxy asphalt as the binder and open-graded gravel as the aggregate material, wherein the mass ratio of epoxy asphalt to crushed stone is 3.0:100, and the design gradation of the aggregate is as follows:
[0031]
[0032] The laying process of the epoxy asphalt gravel drainage base is as follows: firstly, clean the surface of the subbase; secondly, spray the epoxy asphalt waterproof adhesive layer evenly, according to 0.4Kg / m 2 thirdly, lay epoxy asphalt macadam drainage base, rolling and forming, pavement thickness is 8cm, and wait for the end of the age to construct the surface layer.
