If you are correct about where the street ends and your property begins - then there was a legal obligation for the municipality to get permission before entering your property for the purpose of paving your land. However, the situation is not so clear in case there is an easement for access across your land to the adjacent business. Especially if that business requested the municipality to pave the easement. You need to consult a local real property attorney regarding such questions, which require careful investigation and some legal research.
