Here is a photo of them de-rubberizing the runway in Beirut Int'l:
Here is a paragraph from their website:
Our cleaning program continues to cover aprons and runways. This cleaning process starts with daily cleaning activities such as manual cleaning & vacuuming of aprons and service roads. This is followed by periodic cleaning which includes mechanical sweeping of taxi Ways with Water Jet & Single Disk, degreasing of Aprons using Sweeper, Degreasing & Cleaning of traffic lines on Aprons & Runways. Another type of periodic cleaning is the Periodic Derubberizing of Runways, especially on the Aviation Marking Lines with Sweeper Derruberizer.
Hope this helps.
It's actually quite gloomy and cool in Beirut now. That's how it is in the winter.

At SFO, a rubber removal company comes out about 4 times a year to remove the buildup. The majority of time they work on the touchdown areas of 28L and 28R. The same company rotates around the different airports up and down the west coast.
