Research progress of epoxy resin application in road engineering
Aims to deeply delve the classification and composition of epoxy resins and their various applications in road engineering,firstly,the classification and composition of epoxy resins were outlined,and the types of commonly used curing agents along with their advantages and disadvantages were summarized.A new type of glassy polymer-type epoxy resin material was introduced,unlike traditional epoxy resins,the unique dynamic covalent bonds of glassy polymer-type epoxy resins conferred the possibility of their regeneration and reuse,further enhancing the application potential of epoxy resins in road engineering.Subsequently,the ring-opening mechanism,polymerization mechanism,and network formation theory of epoxy resins were pointed out,and scientific guidance for the actual composite processes of epoxy resins was provided.Then,the structure,properties,and classification of epoxy asphalt were outlined,and the main modification methods of epoxy asphalt by scholars at home and abroad were discussed,the main issues in the compatibility,flexibility,and retention time of epoxy asphalt were explored and the existing improvement technologies and methods was summarized.Furthermore,the engineering application examples and research status of epoxy resin in bridge engineering,tunnel engineering,and pavement engineering were reviewed.By elucidating the different application methods and scenarios of epoxy resin in road engineering,the wide application possibilities and application value of it in the field of road engineering were showcased.The results show that epoxy resin has demonstrated excellent performance and great application potential in road engineering.With regard to the renewability and reparability of glassy epoxy resins,future research should focus more on these areas to promote the continuous development and innovative application of epoxy resin materials,providing a significant theoretical and practical foundation for the innovation and application of road engineering materials.8 tabs,7 figs,96 refs.
