Hi.  Your request to review your mappings. 
Fine mapped.  It is difficult to decide which road to map. Focus on highways connecting settlements, Where multiple traces go to same direction, just map one. 
Measure the width of a trace by drawing a round building between the shoulders. If it stays below 2 mtr tag it as a path. Otherwise, unclassified. No need to tag highways within (small) settlements as residential. Just unclassified.
Except for main highways, the highways are mostly unpaved. You can add that to the roads. 
Best regards
