experiment example 1
[0043] First, clean the limestone material and put it into a 100-120°C oven to preheat;
[0044]Based on the quality of limestone material, weigh 1.0% of the asphalt, put it into an oven at 130-165°C to preheat until it reaches a liquid flow state;
[0045] Preheat the mixing pot to 130-165°C, then add the preheated limestone material and asphalt, and stir for 90s; then take it out and let it cool.
experiment example 2
[0047] Except for the following, the rest is the same as in Experimental Example 1.
[0048] The amount of asphalt used is 1.5% of the mass of limestone material.
experiment example 3
[0050] Except for the following, the rest is the same as in Experimental Example 1.

The invention belongs to the field of road engineering, and particularly relates to a pavement seal coat structure and a construction method thereof. According to the pavement seal coat structure, the rubber particles subjected to surface treatment are adopted to replace part of stone materials to serve as the aggregate, the original effect of the pavement seal coat can be ensured while the use amount of waste rubber is greatly increased, the rubber performance can be exerted to the maximum extent, and the shock absorption and noise reduction capacity of a pavement is improved. The construction method does not need large construction equipment, has the characteristics of low construction cost and convenience in construction, and has remarkable economic and social benefits.
Description
technical field [0001] The invention belongs to the field of road engineering, and in particular relates to a noise-reducing resource-friendly road seal structure based on the reuse of waste rubber tires and a construction method thereof. Background technique [0002] The gravel seal layer of road pavement is mainly composed of asphalt binder and aggregate embedded above the binder. It is widely used in the United States, Canada, Australia, South Africa and Europe and other countries or regions. The pre-maintenance structure of pavement such as layer cover and thin layer of hot mix asphalt concrete, gravel seal layer is more durable, efficient and economical maintenance. [0003] At present, hundreds of millions of waste rubber tires are produced every year in the world. Due to the difficulty of compression and the presence of heavy metals such as lead, chromium and cadmium, waste rubber tires occupy a large amount of land space resources and are not easy to biodegrade.
