Problems solved by technology

Technologists have done a lot of work on this for two decades, but the ruts have not been completely resolved
At present, various countries have researched and developed many modified materials, such as APAO, EVA, PE, SBS, SBR, etc., but due to the high price of such polymer modifiers (tens of thousands or tens of thousands of yuan per ton), some are not easy to produce. Miscibility with base asphalt, complex production equipment and other factors, ultimately cannot be widely used

Embodiment 1

[0018] Embodiment 1, the equipment used in this embodiment consists of modifier addition system (mainly including modifier feeding hoist), colloid mill, matrix asphalt and modified asphalt delivery system, air circuit (including air compressor) and pneumatic Asphalt valve switch system, electrical control system (including console, computer), heating system (heat-conducting oil furnace burner) and three processing tanks (mixing tank, grinding tank, finished product tank), among which the colloid mill is made by German SIEFER company Developed SIEFER G-20 colloid mill. This embodiment is a fully automatic processing system, and its processing flow chart is as follows figure 1 shown. Combine below figure 1 Take 5 tons of matrix asphalt as an example to describe the present embodiment in detail:

[0019] 1. Preparation before production

[0020] (1) Turn on the main power switch of the equipment, then turn on the mixing tank, grinding tank, finished product tank switch, modif...

Embodiment 2

[0032] Embodiment 2, need to use colloid mill in embodiment 1, this equipment price is higher, is not suitable for small-scale production. Under the condition of no colloid mill, RS2000 anti-rutting modified asphalt can also be produced by increasing the temperature of the mixture and increasing the mixing time. Its production equipment compared with embodiment 1 has saved colloid mill and grinding tank. Its production process is as follows:

[0033] 1. Preparation before production

[0034] (1) Turn on the main power switch of the equipment, then turn on the mixing tank, finished product tank switch, modifier feeding hoist, air compressor, console, heat conduction oil furnace and other small switches, turn on the computer, and enter the production interface.

[0035] (2) Turn on the burner of the heat transfer oil furnace for continuous heating.

[0036] (3) Arrange the base asphalt to enter the site and raise the temperature to 150°C.

[0037] (4) RS2000 is internally bl...

Abstract

The invention provides a RS2000 anti-rutting modified asphalt processing technic which belongs to the road and bridge engineering technique field, relates to a road asphalt processing technique. The technique uses a technical scheme as follows: the RS2000 anti-rutting modified asphalt is prepared by adding RS2000 modifying agent to basic asphalt which has characteristics that: adding 8% modifying agent into the basic asphalt evenly, heating to 160-170 DEG. C, and stirring 30 minutes with a stirring speed 350 revolutions per minute. The technique also can use a technical scheme as follows: adding RS2000 modifying agent into the basic asphalt which has characteristics of: adding 8% RS2000 modifying agent into the basic asphalt with 150-160 DEG. C, stirring 10 minutes, then rubbing the mixed material twice by a colloid mill. Compared with the prior modified asphalt, the modified asphalt provided by the invention has excellent performance and low cost.

Description

technical field [0001] The invention belongs to the technical field of road and bridge engineering, and relates to a processing technology of road asphalt. Background technique [0002] Rutting is a technical problem with asphalt pavements. Over the past two decades, technical workers have done a lot of work for this, but the ruts have not been completely solved. [0003] The traditional solution mainly starts with improving the performance of materials. The key factor to solve the rutting of asphalt pavement is asphalt binder, and improving the performance of asphalt is one of the main means to improve the rutting of asphalt pavement. One of the keys to an anti-rutting solution is anti-rutting modified asphalt. At present, various countries have researched and developed many modified materials, such as APAO, EVA, PE, SBS, SBR, etc., but due to the high price of such polymer modifiers (tens of thousands or tens of thousands of yuan per ton), some are not easy to produce. ...
