It isn't Phuoc Vinh. That's a great map - I can confirm that this airfield does appear on it
Here's an image of the runway.
the url for the map has a comma in it in error - here's a link to it:

Edit to add: The road on the right that goas around the end of the runway and bends around to the left looks like it still exists.
