Embodiment 1

[0023] The AC-13 pavement is selected, and the original pavement detection conditions are that the structure depth is 0.5mm, the friction pendulum value is 45BPN, and the water seepage coefficient is 47mL / min.

[0024] Under the temperature condition of 30°C, the construction process is as follows: Step 1) The bottom layer is to mix the components of the epoxy asphalt adhesive material according to the requirements, and then spray it evenly on the asphalt pavement with a certain pressure, and spread a layer evenly at the same time fine sand. Step 2) The surface layer is to cover the surface with a layer according to the method of step 1) after the bottom layer is cured to form a waterproof and anti-skid protective layer.

[0025] The amount of epoxy asphalt bonding material used for the bottom layer is controlled at 0.3kg / ㎡, and the amount of fine sand spread is 0.1kg / ㎡.

[0026] The amount of epoxy asphalt bonding material used for the surface layer is controlled at 0.2kg / ㎡,...

Abstract

The invention discloses a fine surface treatment method for a double-layer spread type bituminous pavement and belongs to the related field of bituminous road maintenance and repair. The fine surface treatment method comprises the steps that (1) according to a base layer, after all components of epoxy asphalt binding materials are stirred evenly as required, the mixture is evenly sprayed to the bituminous pavement with certain pressure, and a layer of fine sand is synchronously and evenly spread; and (2) according to a surface layer, after the base layer is solidified, the surface of the base layer is covered with a layer in the mode of the step (1) to form a waterproof antiskid protective layer. According to the fine surface treatment method, the old bituminous pavement can be repaired fast, the antiskid capacity of the pavement and the road appearance are improved.

Description

technical field [0001] The invention relates to the related fields of asphalt pavement maintenance and repair, in particular to a method for fine surface treatment of double-layer asphalt pavement. Background technique [0002] As a seamless continuous pavement, asphalt pavement is widely used in high-grade highway construction because of its smooth surface, comfortable driving, wear resistance, low noise, short construction period, and convenient maintenance. [0003] Due to various reasons such as the complexity and variability of asphalt pavement engineering itself, structural design and construction quality control, coupled with factors such as increasing traffic volume, channelization of vehicles, aggravation of overloaded transportation and water damage, asphalt Early damage such as cracks, ruts, loose surfaces, potholes, etc. appear on the road surface (or bridge deck pavement layer) in varying degrees, which seriously reduces the performance of the road surface (or b...
