Doing some research, I found that by the end of this March the Toncontin runway repairs were finished by the airport authority, including a brand new layer of asphalt. It also included an additional of 300 feet of runway, but they were unable to get more lenght because of lack of government funding to buy the land from the owners.
While searching for that info, I read a statement made today by some engineer, saying that the runway repair personnel did not clean oil that is used while placing the asphalt layer, something as an emulsifier. Also read in another newspaper that the runway had to be vapor cleaned after the asphalt application, which they did not do.
I would not like to comment if the runway had grooves or not before I can confirm, but you know ...............
