Problems solved by technology

[0004] The present invention provides a preparation method of a polymer modified asphalt material, which has a very high hydrophobic effect and has the beneficial effect of anti-blocking function, and solves the problem that the polymer modified asphalt material mentioned in the above background technology is difficult to adapt to the road surface In addition, the asphalt on the road has very poor permeability to rainwater and does not have a hydrophobic effect, resulting in long-term accumulation of rainwater, reducing friction on the road surface, and causing great danger to driving vehicles. , and the existing asphalt is usually laid on the foundation of cement and other materials, which leads to extremely poor water flow and expands the accumulation of rainwater, so it is necessary for the roadbed to provide support for the asphalt and guide water flow.

Embodiment 1

[0032] It is necessary to make the modified asphalt polymer material 2 have a hydrophobic function to ensure the rapid drainage of rainwater on the road surface, please refer to Figure 1-4 , and discloses a method for preparing a polymer-modified asphalt material, wherein a polymer-modified asphalt material includes an integrated material layer 1 and a foundation 30 under the integrated material layer 1, and the interior of the integrated material layer 1 is symmetrically installed with Adhesive material 3, modified asphalt polymer material 2 is installed between the two adhesive materials 3, upper diversion hole cylinder 11 is installed inside the integrated material layer 1, combined roadbed frame 4 is installed on the foundation 30, combined roadbed frame The two sides of 4 are provided with limiting edge 21, and the interior of combined subgrade frame 4 is provided with permeable hole 5, and the inside of modified asphalt aggregate material 2 is symmetrically installed wit...

Embodiment 2

[0035] The height of the existing pavement will move down slightly after being heavily pressed by the vehicle for a long time, but the lowering will affect the overall hydrophobicity of the integrated material layer 1. This embodiment is an improvement made on the basis of embodiment 1. Specifically, see Figure 1-4 , the diameter of the upper diversion hole cylinder 11 is 0.3 centimeters, the lower end of the upper diversion hole cylinder 11 is equipped with a lower diversion column 12, and the upper diversion hole cylinder 11 is used for inserting in the lower diversion column 12, and the upper strata The outside of the diversion hole cylinder 11 is provided with a hypotenuse 13 , and the bottom of the lower diversion column 12 is provided with a fixed foot 14 .

[0036]When the overall height of the integrated material layer 1 decreases, the upper diversion hole cylinder 11 will fall simultaneously with the height of the integrated material layer 1, and the lower end of the...

Embodiment 3

[0038] After the rainwater is discharged into the infiltration hole 5, it needs to be discharged to avoid accumulating inside the device. This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-5 , the inside of the combined subgrade frame 4 is also provided with a diversion cavity 24, the diversion cavity 24 is used to communicate with two permeable holes 5, and the inside of the diversion cavity 24 is equipped with a support shaft 25.

[0039] After the rainwater is discharged into the infiltration hole 5 , it will flow into the combined roadbed frame 4 , be collected by the combined roadbed frame 4 , and be discharged uniformly, and the supporting shaft 25 can increase the supporting strength of the diversion chamber 24 .

Abstract

The invention relates to the technical field of asphalt pavement preparation, and discloses a preparation method of a polymer modified asphalt material.The polymer modified asphalt material comprises an integrated material layer and a foundation below the integrated material layer, and attaching materials are symmetrically installed in the integrated material layer; a modified asphalt polymeric material is installed between the two attaching materials, an upper-layer flow guide hole cylinder is installed in the integrated material layer, a combined roadbed frame is installed on the foundation, limiting edges are arranged on the two sides of the combined roadbed frame, permeation holes are formed in the combined roadbed frame, and a lower-layer flow guide hole cylinder is installed in the permeation holes. And steel cable net layers are symmetrically mounted in the modified asphalt polymeric material. Through cooperation of the steel cable net layer and the supporting columns, the loading capacity of the modified asphalt polymeric material is greatly improved, the multidirectional tensile function is achieved, the whole integrated material layer has the large-weight supporting effect, and therefore the device can adapt to various use environments.

Description

technical field [0001] The invention relates to the technical field of asphalt pavement preparation, in particular to a preparation method of a polymer modified asphalt material. Background technique [0002] Modified asphalt is the addition of external additives (modifiers) such as rubber, resin, high molecular polymer, ground rubber powder or other fillers, or taking measures such as mild oxidation of asphalt to make asphalt or asphalt mixture The performance of asphalt is improved. Asphalt pavement refers to various types of pavement that are paved with road asphalt materials mixed with mineral materials. [0003] The existing single modified asphalt material is difficult to adapt to the use of the road surface, and the asphalt on the road surface has extremely poor passability for rainwater and does not have a hydrophobic effect, resulting in long-term accumulation of rainwater, which reduces the friction of the road surface. However, the existing asphalt is usually lai...
