Case Closed. Case Resolved. What you see on the roadway is a type of pavement preservation called 'crack seal'. The purpose of this is to give the roadway a few more years of life before it needs to be resurfaced. The random patterns are simply where the cracks have been covered. This will prevent salt, sand, etc. from seeping into the cracks and heaving the road. It's applied on a 'per neighborhood' basis which may explain why you see it on some adjacent streets and not others. Thank you for your question!
