Embodiment 1
[0050] Such as figure 1 As shown, a luminous permeable concrete road based on recycled aggregates, the road includes a permeable cushion 1, a permeable base layer 2 and a luminous permeable surface layer 3 laid sequentially from bottom to top, and the surface of the luminous permeable surface layer 3 is painted with Luminous water-permeable surface layer sealant 4; water-permeable cushion layer 1 includes pressed ceramsite 5 and low-quality recycled aggregate 6 laid sequentially from bottom to top; water-permeable base layer 2 is the first high-quality recycled aggregate permeable concrete 9; luminous water-permeable surface Layer 3 includes luminous permeable concrete 7 and the second high-quality recycled aggregate permeable concrete 8; the luminous permeable surface layer sealant 4 adopts double propylene polyurethane sealant. Among them, the laying thickness of the permeable cushion layer 1 is 60mm; the laying thickness of the permeable base layer 2 is 80mm; the laying thi...
Embodiment 2
[0066] Except that the laying thickness of the permeable cushion layer 1 is 40mm; the laying thickness of the permeable base layer 2 is 50mm; the laying thickness of the luminous permeable surface layer 3 is 50mm; The mass ratio of aggregate to cementitious material is 85:15; the second highest quality recycled aggregate permeable concrete 8 is made by mixing the second highest quality recycled aggregate and cementitious material slurry, and the second highest quality recycled aggregate The mass ratio to the gelling material is 95:5. The water absorption rate of low-quality recycled aggregate is 4.0%, and the bulk density is 1100Kg / m 3 , the apparent density is 2.45g / cm 3 , the crushing value is 14%, the needle flake particle content is 4%; the water absorption rate of the first high-quality recycled aggregate is 2%, and the bulk density is 1275Kg / m 3 , the apparent density is 2.65g / cm 3 , the crushing value is 8%, the content of needle flake particles is 0.5%; the water ab...
Embodiment 3
[0068] In addition to the laying thickness of the permeable cushion 1 is 80mm; the laying thickness of the permeable base layer 2 is 76mm; the laying thickness of the luminous permeable surface layer 3 is 63mm; the thickness of the luminous permeable surface sealer 4 is 3mm, the first high-quality regeneration The mass ratio of aggregate to cementitious material is 95:5; the second high-quality recycled aggregate permeable concrete 8 is made by mixing and stirring the second-highest-quality recycled aggregate and cementitious material slurry, and the second-highest-quality recycled aggregate The mass ratio to the gelling material is 85:15. The water absorption rate of low-quality recycled aggregate is 5.5%, and the bulk density is 1300Kg / m 3 , the apparent density is 2.65g / cm 3 , the crushing value is 18%, the content of needle flake particles is 6%; the water absorption rate of the first high-quality recycled aggregate is 4%, and the bulk density is 1400Kg / m 3 , the apparen...
