Problems solved by technology

[0002] In the construction of traditional garden road pavement, the heat island effect is likely to occur due to the increase of surface temperature and humidity during the evaporation process after rain; and when the drainage facilities are not fully constructed, it is easy to be waterlogged, and the color and form of the asphalt concrete pavement are usually relatively single, lacking beauty

Embodiment Construction

[0041] Permeable concrete has a microporous structure, which can be referred to figure 2 , Permeable concrete is characterized by using single-grain coarse aggregate as the skeleton, and a thin layer of cement paste or a thin layer of mortar with a small amount of fine aggregate is wrapped on the surface of the coarse aggregate particles as a cement layer between the aggregate particles to form the skeleton ——Porous concrete materials with pore structure, due to the special gradation of aggregates, form a honeycomb structure, or called rice candy structure. by figure 1 It can be seen that water-permeable concrete is a porous aggregate structure formed by cementing a thin layer of hardened cement slurry between coarse aggregate particles. It contains many pores, and most of them are large pores with a diameter of more than 1mm, so it has good water permeability. Sex.

[0042] The present invention will be further described below in conjunction with the accompanying drawings and s...

Abstract

The invention discloses a garden road colored asphalt pervious concrete construction method, and relates to the technical field of pavement construction. According to garden path requirements, soil meeting the design requirement is selected for layered backfilling and layered compaction of the plain soil roadbed; the foundation flatness of the roadbed is detected; after compaction, a cutting ringis used for sampling to check the roadbed quality; the density coefficient is greater than or equal to 0.93; graded broken stones are paved continuously; construction of a cushion layer is firstly carried out during graded broken stone paving; a sand filter layer is laid; and a pervious concrete base layer is poured by firstly pouring pervious concrete on the bottom layer, pouring pervious concrete on the surface layer, maintaining the pervious concrete base layer, paving road shoulder stones after construction and maintenance of the pervious concrete base layer, and continuing asphalt sealinglayer construction, carrying out asphalt bonding layer construction, and carrying out asphalt surface layer construction and maintenance.

Description

Technical field [0001] The invention discloses a construction method, which relates to the technical field of pavement construction, in particular to a construction method of colored asphalt permeable concrete for garden roads. Background technique [0002] In the construction of traditional park road pavement, the heat island effect is likely to occur due to the increase of surface temperature and humidity during the evaporation process after the rain; and when the drainage facilities are not completed, it is prone to waterlogging, and the color and form of the asphalt concrete pavement are usually relatively simple and lacking. Beauty. However, the application of colored asphalt permeable concrete in garden roads improves the risk of waterlogging when drainage facilities are incomplete. The color and form of garden roads are usually relatively simple, lacking aesthetic problems, but the existing color asphalt permeable concrete construction for garden roads The construction qu...
