preparation example Construction

[0028] Further preferably, the colored modified epoxy resin is prepared by the following method.

[0029] Preferably, the embodiment of the present invention also provides a preparation method of a colored modified epoxy resin. The method comprises the steps of:

[0030] S01. Weigh each component material according to the above-mentioned color modified epoxy resin;

[0031] S02. Premixing the silane coupling agent with the nano diatomaceous earth to obtain a first mixture;

[0032] S03. Preheating epoxy resin, adding the first mixture into the preheating epoxy resin, fully mixing, then adding the diluent, the stabilizing agent, and the defoamer in turn, mixing and stirring at 70 Incubate at -80°C for 0.5-1h to obtain the colored modified epoxy resin.

[0033] In the above-mentioned step S01, each component material is weighed according to the above-mentioned colored modified epoxy resin, which is consistent with the above-mentioned discussion. In order to save space, detail...

Embodiment 1

[0064]Use a road roller to roll and finish the original soil subgrade to form a subgrade; select 4% cement-stabilized graded gravel as the non-motor vehicle road base material, and after paving and rolling, the thickness is 30cm; use high-viscosity modified asphalt as anti-seepage For the bonding layer, the amount of spraying is 1.2kg / ㎡, and 0.3-0.6mm gravel is spread synchronously to ensure that the gravel coverage area is about 60%-80%; mix the raw materials of the colored green road surface layer to obtain a mixture, Spread the mixture evenly on the impermeable adhesive layer to ensure that the loose paving thickness is equal to the horizontal line; after the paving length reaches 20m, use the principle of rolling 2 times with a 1-ton small road roller to obtain the obtained product. Describe the colored greenway.

[0065] The raw materials of the colored green road surface layer include 60 parts of coarse aggregate, 30 parts of fine aggregate, 4 parts of filler, 7 parts of...

Embodiment 2

[0068] The original soil subgrade is rolled and polished by a road roller to form a subgrade; 4% cement stabilized graded stone powder slag is selected as the non-motor vehicle road base material, and after paving and rolling, the thickness is 40cm; water-based epoxy resin and water-based curing agent are used After mixing according to the proportion, it will be used as an impermeable bonding layer, and the spraying amount is 0.6kg / ㎡; synchronously spread 0.3-0.6mm gravel to ensure that the gravel coverage area is about 60%-80%; mix the colored green The raw materials of the road surface layer are mixed, and the mixture is evenly spread on the permeable layer to ensure that the loose paving thickness is equal to the horizontal line; after the paving length reaches 20m, the principle of rolling with a 1 ton small road roller is rolled twice , the colored green channel can be obtained.

[0069] Water-based epoxy resin and water-based curing agent are mixed in proportion as an an...

Abstract

The invention provides a pavement structure of a colored greenway. The pavement structure of the colored greenway comprises a roadbed, a pavement base layer, an impermeable bonding layer and a coloredgreenway pavement layer which are sequentially arranged in a stacked mode, wherein the pavement base layer is arranged on the other face, making contact with the ground, of the roadbed; the impermeable bonding layer is arranged on the side, away from the roadbed, of the pavement base layer; and the colored greenway pavement layer is arranged on the side, away from the pavement base layer, of theimpermeable bonding layer. Raw materials of the colored greenway pavement layer comprise the following components (by weight): 100-102 parts of epoxy resin, 10-20 parts of coarse whiting powder, 5-10parts of silica fume, 1-5 parts of nanometer diatomite, 1-5 parts of a silane coupling agent, 3-6 parts of a toner, 0.5-1 part of an anti-aging agent, 0.5-1 part of a dispersing agent, and 1-2 parts of a stabilizer.

Description

technical field [0001] The invention relates to the field of urban road materials, in particular to a pavement structure and method for colored greenways. Background technique [0002] Sponge city is a new concept of ecological city. Its most important feature is "absorbing water, storing water, seeping water, purifying water when it rains, and releasing water when needed". The construction of sponge city needs to improve several aspects such as underground comprehensive pipe gallery, permeable pavement pavement, and permeable non-motor vehicle lane pavement. Among them, the research on underground comprehensive pipe gallery and permeable pavement pavement is relatively sufficient, although there are not many implementation cases. But the theoretical feasibility is already high. [0003] At present, urban bicycles are prevalent, and more and more people choose bicycles for environmentally friendly travel. This puts forward higher requirements for greenway pavement, which re...
