Problems solved by technology

When the traditional slurry seal is laid on the original road surface, its compactness is poor, which makes the water seepage resistance and erosion resistance poor, which makes the life of the slurry seal layer extremely short, which leads to the need for repeated laying of the road surface, which not only causes Huge economic loss, but also increased the workload of road maintenance

Abstract

The invention discloses an anti-permeable and corrosion resistant asphalt base composite sealing layer structure. The anti-permeable and corrosion resistant asphalt base composite sealing layer structure successively includes a gravel sealing layer, a first thin pulp sub-layer and a second thin pulp sub-layer from top to bottom; the gravel sealing layer is prepared from the following materials inparts by weight: 10-20 parts of SBS modified emulsified asphalt, 80-100 parts of a filler, 15-30 parts of water and 5-7 parts of a compatilizer. The anti-permeable and corrosion resistant asphalt basecomposite sealing layer structure successively includes the gravel sealing layer, the first thin pulp sub-layer and the second thin pulp sub-layer from top to bottom, by optimizing the composition ofeach layer, the internal structure of the asphalt is improved at the micro level, excellent tenacity is achieved, anti-permeability and corrosion resistance are good, and good stability and durability are achieved.

Description

technical field [0001] The invention relates to a pavement material and a preparation method thereof, in particular to an anti-seepage and anti-corrosion asphalt-based composite seal layer structure. Background technique [0002] The slurry seal layer is a thin layer formed by mixing emulsified asphalt, coarse and fine aggregates, fillers, water and additives according to the designed ratio by mechanical equipment and spreading it on the original road surface. The traditional slurry seal layer is mostly It is mainly made of ordinary emulsified asphalt, which has the advantages of smooth surface, comfortable driving, good wear resistance, small vibration and low noise. When the traditional slurry seal is laid on the original road surface, its compactness is poor, which makes the water seepage resistance and erosion resistance poor, which makes the life of the slurry seal layer extremely short, which leads to the need for repeated laying of the road surface, which not only cau...
