Problems solved by technology

Therefore, the difference in softening point cannot be used to judge the stability of waste tire rubber powder rubber asphalt
Moreover, this method is not a test and evaluation method for judging the segregation degree of modified asphalt, but a test method for judging the difficulty of segregation of modified asphalt, and it cannot solve the problem of how to deal with waste tire rubber powder rubber asphalt after segregation

Embodiment Construction

[0027] Below in conjunction with embodiment the present invention is described in further detail.

[0028] Example conditions: the design content of waste tire rubber powder in rubber asphalt is 20%. After production, it will be transported 700km for 24 hours to the asphalt mixing plant. The temperature of waste tire rubber powder rubber asphalt will drop from 200°C to 160°C, and segregation has occurred, use the method of the present invention to determine whether it can be used directly.

[0029] A kind of waste tire rubber powder rubber asphalt segregation test and evaluation method, the method comprises the following steps:

[0030] The first step is to draw the standard density map of waste tire rubber powder rubber asphalt:

[0031] Draw a standard density map of waste tire rubber powder rubber asphalt before mass production, see figure 1 , the waste tire rubber asphalt is produced in the laboratory, the materials and production process are the same as those in mass pr...

Abstract

The invention provides a waste tire rubber powder asphalt separation test and an evaluation method. The method comprises the following steps: firstly, drawing a waste tire rubber powder asphalt standard density graph; secondly, measuring the density of separated waste tire rubber powder asphalt, wherein the operation is needed only in case of separation of the waste tire rubber powder asphalt; thirdly, calculating corresponding content of waste tire rubber powder; further calculating the content difference of the waste tire rubber powder; finally, judging the separated waste tire rubber powder asphalt. The method aims to detect the separation degree of the waste tire rubber powder asphalt and judge whether the separated waste tire rubber powder asphalt can be directly used or not. A main experimental instrument used in the method is a common pycnometer, no special experimental instrument is needed, tests and calculation methods are simple, the evaluation method is easy to master and is practical and rapid, construction can be accurately instructed, waste can be avoided, and the efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of road waste tire rubber powder rubber asphalt, in particular to a separation test and evaluation method of waste tire rubber powder rubber asphalt. Background technique [0002] At present, my country's waste tires have caused serious environmental pollution and continue to increase. The application of waste tire rubber powder processed from waste tires in road construction is technically feasible and the quality of the project can be guaranteed. The reuse of tires has found a good way. Therefore, the application of waste tire rubber powder rubber asphalt in road asphalt pavement is increasing and the growth rate is very fast. [0003] Waste tire rubber powder rubber asphalt is a modified asphalt made by mixing waste tire rubber powder into matrix asphalt through swelling, network filling, cross-linking or degradation. According to regulations, the content of waste tire rubber powder (internal mixing) is n...
