Hello Thai 
Community,
This is Salim from TomTom.
It may be helpful to you to take part in a MapRoulette challenge related to Add Surface to Highway in Thailand.
The goal of this challenge is to identify and add missing surface tags on motorways and motorway links as they represent high speed roads, and it is desirable to accurately tag the surface for these highways. We queried OSM for ways with certain highway=* values where the surface tag was missing.
Whenever you have questions or comments, feel free to contact me - and happy editing!
