聚合物改性沥青的相态结构

Phase Structure of Modified Asphalt

聚合物改性沥青是由聚合物和沥青组成的两相共混物 ,按照相的连续性可以分成 3种基本类型 :第 1种是沥青相为连续相而聚合物相为分散相的单相连续结构 ;第 2种是聚合物相为连续相而沥青相为分散相的单相连续结构 ;第3种为两相连续结构或两相互锁结构 。

Polymer modified asphalt (PMA) is a kind of 2-phase structure composed of polymer and asphalt. PMA can be classified into three categories, first, single phase structure with continuous asphalt phase and dispersed polymer phase, second, single phase structure with continuous polymer phase and dispersed asphalt phase, third, two-phase continuous structure or two-phase interlocked structure, i. e. both asphalt and polymer phases are continuous.
