Problems solved by technology

[0004] Although grass-planting ecological asphalt mixture can introduce plants and allow water and air to pass through, if it is used as a roadbed pavement, the pores are easily blocked, and it has no effect of purifying water and has no greening effect

Embodiment

[0052] Fine asphalt mixture layer: take: rock asphalt, E-51 epoxy resin, methyl hexahydrophthalic anhydride and hydrophilic additives, use shear mixing method, control the stirring rate at 2500r / min, at 100 Stir at a stirring temperature of ~150°C for 60-70 minutes and stop stirring when the uniformity of the mixture is good;

[0053] Pour the prepared plant-type asphalt mixture into the container, develop it in a constant temperature box at 150°C for about 1 hour, take it out, and then stir it at 150°C for 10 minutes, and then it can be poured into a fine asphalt mixture layer. Block structure, and finally control the stable ambient temperature and humidity for maintenance.

[0054] Concrete raw material proportioning ratio is as shown in table 1 below:

Abstract

The invention provides a grass planting ecological sponge type bituminous mixture pavement structure which sequentially comprises a fine bituminous mixture layer, a coarse bituminous mixture layer, a water permeable cloth layer, a water purification and filtering layer, a waterproof film layer and a roadbed layer from top to bottom. The bottom layer of the water purification and filtering layer is provided with a drainage pipe layer by extending outwards. The thickness of the fine bituminous mixture layer is 3-5 cm, the thickness of the coarse bituminous mixture is 8-12 cm and the thickness of the water purification and filtering layer is 12-25 cm. The bituminous mixture layers are composed of bituminous materials and plantation base materials. According to the method, separation of trivalent chromium and hexavalent chromium is achieved by adoption of a liquid chromatography system, the chromium content is measured through ICP-MS, the analysis effect can be ensured, the pretreatment operation procedure can further be simplified, and the detection requirements of the new toy directive of European Union for the migration amounts of the trivalent chromium and the hexavalent chromium can be completely met.

Description

technical field [0001] The invention relates to the technical field of permeable pavements, in particular to a planting sponge type asphalt mixture pavement structure. Background technique [0002] In recent years, with the continuous development of our country's social economy, the large-scale and unprecedented number of civil engineering construction activities carried out in major and medium-sized cities have caused a load on the environment that cannot be ignored. Traditional roads, harbors, revetments and other engineering components are generally composed of concrete made of cement, stone, steel, sand and other materials. They are closed and impermeable, and plants cannot grow. This completely destroys the natural water and soil environment and has a significant negative impact on the ecological environment. ;Modern cities are covered by buildings, impermeable roads and fields. The closed concrete masonry has no water permeability and air permeability. Urban flooding ...
