Asphalt pavement permeable diversion road flat stone and diversion road structure

Abstract

The invention discloses an asphalt pavement permeable diversion road flat stone and a diversion road structure. The asphalt pavement permeable diversion road flat stone includes a diversion road flatstone body, a tamped soil layer, a pavement, a permeable road edge stone and an asphalt road surface layer. The pavement, the permeable road edge stone and the asphalt road surface layer and the diversion road flat stone are arranged above the tamped soil layer, the permeable road edge stone is arranged on one side of the pavement, one side of diversion road flat stone is close to the permeable road edge stone, the other side of the diversion road flat stone is connected with an asphalt road surface, and the diversion road flat stone is arranged above a sewage disposal well ditch. The size ofthe prepared diversion road flat stone can be changed according to the specific requirements of road traffic design, the thickness is no less than 60MM, diabase and the like or the other broken stonesare arranged on the bottom layer, permeable cement is of a porous structure, and the surface layer is arranged to be of a cement-based or polymer-silica sand fine hole structure. The compressive strength of the prepared diversion road flat stone is more than and equal to 45 MPa, the flexural strength is more than and equal to 4.0 MPa, the city vehicle-mounted load capacity can be completely met,and the surface layer is fine in holes and abrasion-resistant and attractive. All-directional seepage drainage is achieved, and the runoff volume is much higher than that of general flat stones.

Description

Technical field: [0001] The invention relates to a permeable road flat stone brick and a diversion path, in particular to an asphalt pavement permeable diversion road flat stone and a diversion path structure. Background technique: [0002] With the continuous acceleration of the national urbanization process and the continuous expansion of urban construction, the need for road hardening is also increasing. With the continuous expansion of the urbanized population and the sharp increase in road traffic pressure, urban waterlogging also often occurs, resulting in urban " The phenomenon of "watching the sea" brings great inconvenience to people's work and life, and creates some safety hazards. Therefore, the country vigorously advocates the construction of sponge cities to solve the problem of urban rainwater drainage. Road leveling stone is a commonly used building material on asphalt pavement. The general materials are granite and cement prefabricated slabs, both of which a...
