The dependence of weight change after heating from the content of water-insoluble fraction of the liquid products of fast pyrolysis in the bitumen has been defined. It was revealed that the weight change after heating the samples with the addition of a water-insoluble pyrolysis liquid in an amount of 0-50% by weight does not exceed 0.5%, which corresponds to the requirements. Also, the dependence of depth of needle penetration on content of liquid products of fast pyrolysis of birch wood in the road bitumen composition has been defined. It was found that with increasing cycles of exposure to heat penetration decreases.
