废胎胶粉的细度在很大程度上影响着橡胶改性沥青的性能,由于在废胎胶粉的生产上要求的某一目数的产品不可能是单一的粒径,而是在一个具体的范围内,且由于我国缺少相应的标准而使得不同厂家生产的同一目数的橡胶粉粒径范围差别较大。在橡胶粉细度控制的室内试验中,不同的试验方法又使得结果有较大的出入。通过橡胶粉细度不同的室内试验方法,运用微观分析的方法和分形理论分析的方法,对橡胶粉的细度特性及不同试验方法得出的结果进行分析,得到橡胶粉分形的特点及不同试验方法下的结果差异特性。
The fineness of waste rubber powder has a great influence on the performance of rubber modified asphalt. Since a certain number of products required in the production of waste rubber powder can not be a single particle size, Of the range, and due to the lack of appropriate standards in our country so that different manufacturers produce the same mesh rubber powder particle size range vary greatly. In the laboratory test of rubber powder fineness control, different test methods make the results have a greater discrepancy. By means of laboratory test with different fineness of rubber powder and microscopic analysis and fractal theory analysis, the fineness characteristics of rubber powder and the results obtained by different test methods are analyzed. The fractal characteristics and different tests of rubber powder Differences in the results under the method.
