yes. the road surface is abraded as it's driven over, which creates oily dust. essentially "microbitumen". also, road usage already causes microplastic pollution in the form of tire wear, so while including plastic in the road surface might increase the overall volume of microplastic pollution, it won't increase the distribution of it - areas near roadways are already microplastic hotspots.
