Abstract: 
Using light fraction of coal tar (5.75 wt % of coumarone and 44.45 wt % of indene), glycidyl methacrylate and styrene, the coumarone-indene resin with epoxy groups (CIRE) has been synthesized. Monoperoxy derivative of diglycidyl ether Bisphenol A (PO) was used as an initiator. The possible formation of CIRE has been studied on the model systems consisting of PO, glycidyl methacrylate, indene or coumarone, or styrene, or mixture of mentioned compounds. The synthesized product has been investigated as a polymer additive to bitumen-polymer blends (BPB). The effect of CIRE amount, temperature and time on the BPB operational characteristics has been examined. By means of IR-spectroscopy the structures of CIRE, bitumen and BPB were determined.
