Technical Field

The invention relates to the field of urban road materials, in particular to a paving structure and a paving method of a color green road.

Background

The sponge city is a novel ecological city concept, and is mainly characterized in that the sponge city absorbs water, stores water, seeps water and purifies water when raining, and releases water when needed. Sponge city construction needs to perfect several aspects such as utility tunnel, permeable pavement, permeable non-motor way pavement simultaneously, and wherein the research in the aspect of utility tunnel and permeable pavement is comparatively abundant, and although the implementation case is not many, theoretical feasibility has been higher.

At present, city bicycle is flourishing, and more people select bicycle environmental protection trip, and this has provided higher requirement to green way pavement, has both required the travelling comfort of driving, requires certain aesthetic property and durability simultaneously. Along with the rapid progress of national economy, people put forward higher requirements on the color and coordination of urban road materials, and accordingly, colored pavements are produced, and the colored pavements are mainly applied to public transport lanes, urban green roads, tourist attraction roads, tunnel entrances and exits, various turning, speed limiting, crossing zones and the like. In order to be different from the traditional black and white road surfaces, more and more green roads in cities adopt color pavement surface layers, and hot-mix color asphalt pavement is mainly adopted for pavement. The paving material has several obvious defects when being used for paving green roads, firstly, the width of the green road is limited, so that the paving and rolling effects of the colored asphalt can not be achieved, and the durability of the paving material is further influenced; secondly, the colors of the colored asphalt pavement are mostly limited to the cementing material, and once the pavement is worn and the color of the original aggregate is exposed, the color of the colored pavement is more diluted; thirdly, the color asphalt belongs to a viscoelastic material system, and the prior art cannot modify the high-viscosity color asphalt, so that if a hot-mix color technology is adopted to prepare a permeable pavement layer, the bonding effect and the water damage resistance are seriously insufficient.

In addition, the raw materials of the common color green road surface layer also include permeable concrete and surface layer color coating, and cold-mix color permeable paving material. The permeable concrete and the surface layer color coating are to coat a layer of color pigment on the surface of the permeable concrete, and the permeable concrete belongs to a cement-based system and needs a certain curing time, so that the permeable concrete is inconvenient to maintain, and the shrinkage of the surface layer color pigment is seriously inconsistent with the shrinkage coefficient of the permeable concrete, so that various uneven cracks are easily caused on the surface layer of the color coating. The cold-mixed colored water-permeable pavement material mainly adopts polyurethane or epoxy resin, the bonding capacity of the polyurethane is limited, and the aggregate peeling disease is easy to occur after the water-permeable pavement layer is made; the epoxy resin material has high bonding capability, but the problem of poor aging resistance is generally generated when the epoxy resin material is used for road materials. In view of the disadvantages of the conventional color paving green road, the use of the color paving green road is limited.
