Problems solved by technology

However, this pavement structure also has obvious disadvantages: First, the water permeability and water storage are poor. When it rains, the rainwater will be directly drained along the urban road drainage system, and in sunny days, water must be sprinkled to ensure that the pavement is wet. Although there are currently some such as The new material of permeable concrete can solve the drainage problem to a certain extent, but its water storage performance is still very poor, and it cannot intercept rainwater. Moreover, when it rains in a short period of time, it is still prone to water accumulation; The air exchanges heat and humidity, which is prone to heat island effect, which makes the temperature of urban roads and even the whole city too high

Abstract

The invention discloses an urban road pavement structure which comprises a drainage layer, a support layer, a foundation layer, a drainage degradation layer and a drainage cooling system. The supportlayer is directly paved on an urban road foundation and comprises a plurality of laminated metal perforated plates and gravel arranged between the metal perforated plates in a filling manner; the drainage layer is arranged below the support layer and is inserted into the urban road foundation; the foundation layer is arranged above the support layer and sinks along the middle portion of the uppersurface of a road in the length direction in an inclined downward manner, the longitudinal section of the foundation layer is in an isosceles trapezoid shape with the large upper portion and the smalllower portion; the drainage degradation layer is arranged above the foundation layer, and the upper surface of the drainage degradation layer is horizontal; and the drainage cooling system comprisesa heat exchange tube, a heat exchange main chamber, and a vertical tube, a pipe cap and a water storage tank; the middle portion of the upper portion of the water storage tank is provided with an opening, and the opening is opposite to the sinking position of the upper surface of the foundation layer. The pavement structure has good stability, has good water permeability and water storage performance and has high pavement high temperature deformation resistance.

Description

technical field [0001] The invention relates to the technical field of urban road paving, in particular to an urban road paving structure. Background technique [0002] In recent years, my country's transportation industry has developed rapidly, and many transportation infrastructures are being constructed in full swing. Among them, the asphalt pavement structure has gradually become a road project due to its characteristics of good driving comfort, easy repair, and low initial cost. The most commonly used pavement structure. However, this pavement structure also has obvious disadvantages: First, the water permeability and water storage are poor. When it rains, the rainwater will be directly drained along the urban road drainage system, and in sunny days, water must be sprinkled to ensure that the pavement is wet. Although there are currently some such as The new material of permeable concrete can solve the drainage problem to a certain extent, but its water storage performa...
