You should, but may have to go to court to vindicate and enforce them. If there is no recorded easement(s), there is presently no right; but if there is no other practical way to get from you home to a public road or vice versa, a court can create an easement "by necessity" to allow access. So if this private road is the only way in/out of your property, if the neighbor tries to block it, you can likely get a court to have him remove the blockage and create an easement.
