The properties of fine-grained asphalt concrete and its modified by bio based epoxy rape oil (BERO) form were studied. Rapeseed oil epoxide (ROE) obtained from renewable and ecological raw materials, rapeseed oil in a composition with initiators (hardeners) was used as a modifier. It was found that the introduction of BERO in the amount of 3% of the mass. allows to increase indicators of limit of durability of asphalt concrete at compression at a temperature of 20 ° C and 50 ° C.
In our time, the use of bitumen modified with epoxy compounds is considered as an
effective means of improving the durability of road pavement. Given the rather long duration
of modification of road bitumen epoxy rapeseed oil (EPO), we studied the processes of
modifying bitumen using ultrasonic cavitation. For research, road bitumen modified with
rapeseed oil epoxy using cavitation and without it. Cavitation in the process of modification of
road bitumen was used to reduce the modification time.
Cross-linking of epoxy-oligomeric mixtures based on ED-20 industrial epoxy dianic resin and TGM-3 oligoesteracrylate in the presence of fluorine-containing peroxy oligomers has been studied. Oligomers used for the cross-linking have been obtained via chemical modification of peroxy derivative of ED-24 epoxy resin with alcohols-telomers by general formula HOCH2–(CF2–CF2)nH, where n is 3 or 4. The thermal stability of peroxy groups in the initial material, fluorine-containing peroxy oligomers and stability of cross-linked films have been examined using derivatographic methods.
The reaction of chemical modification of ED-20 epoxy resin with isopropylbenzene hydroperoxide has been studied. The process duration effect on the reaction between resin and hydroperoxide has been determined. The possibility to use the synthesized product as a component in the process of epoxy-oligoesteric compositions crosslinking with application of hardeners various by their nature has been studied.
