Problems solved by technology

[0002] Usually, the maintenance of asphalt pavement and cement pavement is limited to the short-term repair of the cracked part. Many bridges are exposed to rainwater at the joints. The repeated driving load shortens the life of the road / road. After repairing, it will go through the maintenance process , not only the process is complicated and the maintenance cost is high, but also the quality of the repair is not good and the service life is not long; although the method of using road sealant to repair cracks has appeared on the market, the traditional hot-melt sealant is only suitable for joints made of surface materials. The fine cracks on the surface of the pavement caused by shrinkage and periodic changes in temperature, but it is no longer applicable to reflective cracks on the pavement caused by the base layer or roadbed

specific Embodiment approach

[0017] A road sealant, said sealant is mainly composed of 29% matrix asphalt by mass percentage, 15% fine rubber powder, 45% fossil powder, 0.4% SBS modified asphalt, 0.4% styrene-butadiene rubber powder, 0.1% active agent, 0.1% tackifier and 10% diesel.

[0018] A kind of production technology of road sealant: described production technology mainly comprises the following steps:

[0019] Step 1: Take the base asphalt according to the above ratio, put the base asphalt in the asphalt circulation tank, turn on the stirring function and the heating function, heat the base asphalt to 150-180°C evenly, then add talcum powder according to the above ratio and stir evenly;

[0020] Step 2: Take SBS modified asphalt, fine rubber powder and styrene-butadiene rubber powder according to the above ratio, put them in a mixing tank, heat them to a molten state, add active agent and tackifier in proportion and stir evenly;

[0021] Step 3: Add the mixture in the molten state in step 2 to the...

Embodiment 1

[0028] Embodiment 1: Adopt technology of the present invention to produce 1 ton of road sealant.

[0029] Get a kind of road sealant, described sealant is mainly by the mass percent of 0.29 tons of matrix asphalt, 0.15 tons of fine rubber powder, 0.45 tons of fossil powder, 0.04 tons of SBS modified asphalt, 0.04 tons of styrene-butadiene rubber Rubber powder, 0.01 tons of active agent, 0.01 tons of tackifier and 0.1 tons of diesel oil, put the base asphalt in the asphalt circulation tank, turn on the stirring function and heating function, and evenly heat the base asphalt to between 150-180 °C Then add talcum powder according to the above ratio and stir evenly; put SBS modified asphalt, fine rubber powder and styrene-butadiene rubber powder into the mixing tank, heat to molten state, add active agent and tackifier in proportion and stir evenly Add the mixture in molten state to the base asphalt in step 1, stir until fully mixed, then cool, and finally add diesel oil in propor...

Abstract

The invention relates to the technical field of road repair, in particular to production and construction technologies of a road sealant applicable to road crack repair of pavements made of various materials. The road sealant mainly comprises 29% by mass of matrix asphalt, 15% by mass of fine rubber powder, 45% by mass of fossil meal, 0.4% by mass of SBS (styrene butadiene styrene) modified asphalt, 0.4% by mass of butadiene styrene rubber powder, 0.1% by mass of an active agent, 0.1% by mass of a tackifier and 10% by mass of diesel oil. The road sealant has high applicability, can be widely applied to crack pouring repair of asphalt pavements such as asphalt and concrete highways, expressways, high-grade highways, urban highways, airport runways and the like as well as seam sealing repair of cement concrete pavements and can be further applied to expansion joints of bridges or structures; when the construction technology is adopted for construction, the driving feeling on the repaired road is excellent, the traffic noise is small, and various problems that cannot be solved with the traditional technology can be solved by the aid of the excellent sealing performance, waterproofness, high-strength adhesion, high-temperature resistance, good low-temperature adhesion and the like of the road sealant.
