Embodiment 1

[0022] First put 10kg of base asphalt into the asphalt heating tank from the drum remover, heat up to raise the temperature of the asphalt to 150°C, the base asphalt will continue to bubble after heating, stop heating when the bubbles stop, and Pour the asphalt into a mixing tank, then add 0.5kg of sulfur into the mixing tank, start the agitator to make the agitator work, control the stirring speed at 300r / min, add 0.2kg of polyvinyl chloride modifier, and swell After the swelling is sufficient, the asphalt mixture in the mixing tank is put into another mixing tank through a colloid mill, and the machine is stopped after all the grinding is completed, and then the ground asphalt in the mixing tank is put into the front through a colloid mill. Put it in a mixing tank, repeat this process for 3 times, and finally pour the ground asphalt into the storage tank, and continue to develop it for 1 hour to get a kind of PVC modified matrix asphalt.

Embodiment 2

[0024] First put 20kg of base asphalt into the asphalt heating tank from the drum remover, heat up to raise the temperature of the asphalt to 170°C, the base asphalt will continue to bubble after heating, stop heating when the bubbles stop, and Pour the asphalt into a mixing tank, then add 1.5kg of sulfur into the mixing tank, start the agitator to make the agitator work, control the stirring speed at 350r / min, add 0.6kg of polyvinyl chloride modifier, and swell After the swelling is sufficient, the asphalt mixture in the mixing tank is put into another mixing tank through a colloid mill, and the machine is stopped after all the grinding is completed, and then the ground asphalt in the mixing tank is put into the front through a colloid mill. Put it in a mixing tank, repeat this way for 4 times, and finally pour the ground asphalt into the storage barrel, and continue to develop for 1.5 hours to get a polyvinyl chloride modified matrix asphalt.

Embodiment 3

[0026] First put 50kg of base asphalt into the asphalt heating tank from the drum remover, heat up to raise the temperature of the asphalt to 180°C, the base asphalt will continue to bubble after heating, stop heating when you see that the bubbles stop, and Pour the asphalt into a mixing tank, then add 5kg of sulfur into the mixing tank, start the agitator to make the agitator work, control the stirring speed at 400r / min, add 2kg of polyvinyl chloride modifier to swell, swell After the asphalt mixture in the mixing tank is fully ground through the colloid mill, it is put into another mixing tank. After all the grinding is completed, stop the machine, and then the ground asphalt in the mixing tank is put into the previous mixing tank through the colloid mill. In the tank, grind it repeatedly for 5 times, and finally pour the ground asphalt into the storage barrel, and continue to develop a PVC modified matrix asphalt for 2 hours.

Abstract

The invention relates to polyvinyl chloride modified base asphalt and a processing method of the polyvinyl chloride modified base asphalt. The method comprises the following steps of pouring base asphalt into a heating tank, sufficiently heating, pouring the heated base asphalt into a stirring tank, adding sulfur, starting a stirrer, adding a polystyrene modifier, repeatedly grinding, stirring and mixing by utilization of the stirring tank, pouring the grinded asphalt into a storage tank for later development for a period of time. The processing method has the advantages of simplicity, easiness in large-scale production and wide application prospects.

Description

technical field [0001] The invention relates to a modified base asphalt, in particular to a base asphalt added with a polyvinyl chloride modifier and a processing method thereof, belonging to the field of asphalt processing. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. Adding road asphalt materials to pave roads in mineral materials can greatly improve road paving performance. The ability of the pellets to resist damage to the road surface by driving and natural factors makes the road surface smooth, less dusty and durable. With the rapid development of China's highways, the total mileage of my country's highways ranks second in the world. A considerable part of my country's road surfaces are paved with asphalt. During the "Twelfth Five-Year Plan" period, the average consumption of road asphalt is about 15 million...
