The chemical structure of modified asphalt is very complex, oxidized asphalt and its relationship with asphalt colloid structure, physical performance and activity characteristics is very complex. Modified asphalt improves the physical performance of asphalt by improving the internal structure of the asphalt system. The mechanism of asphalt modification production is introduced.

Modified asphalt compatibility system has two meanings: one is the physical stability of the system, that is, the polymer particles and asphalt are not different in the heat preservation process; the second is chemical stability, that is, chemical stability. E. In the process of thermal insulation, the performance of educational modified asphalt will not change significantly at any time. The compatibility and stability of the modified asphalt can be obtained by studying the compatibility between the main asphalt and the polymer and adding the corresponding additives.

Asphalt and polymer mixture form a compatible system, which performs the function of asphalt. According to the principle of asphalt modification, whether it is the swelling and distribution of the adsorbed polymer petroleum in the asphalt, or the adsorption polymer in the asphalt After the expansion and formation of the oxidized asphalt continuous phase, the petroleum has the high temperature and low temperature functions of the asphalt through the existence of the polymer, so that the asphalt components are compositely distributed in the polymer phase. The adsorption of oil constitutes a continuous network and plays a key role in the modification of the polymer.

After the asphalt is modified, its chemical structure and asphalt molecules are not changed. It is easy to absorb the plump part of the asphalt and swell. After the swelling, the polarity of the asphalt is close to colloidal aluminum, and the partial compatibility changes the distribution of asphalt components, which has an impact on the phase transition of the asphalt. The bituminous fraction on the polymer particles is completely swollen, and the adsorption of the bituminous fraction by the polymer particles is the basis of the polymer modification and the performance of the running bitumen. The expansion of the composition of the polymer particles by the asphalt and the adsorption of the asphalt fraction by the polymer particles is a dynamic process, which will have an important impact on the three-dimensional structure and function of the modified asphalt.If you have any other questions, please contact us for oxidized asphalt details or contact us directly.
