Pretty neat how quickly they can add the fancy red zebra crossings to an intersection. Would be interesting to see a video of how they stamp and colour the pattern (assuming this is how it is done).

They heat the pavement to soften it up first, and then put a grid (in the form of the faux brick pattern) on top of the now-soft pavement.  They then use a plate compactor to press the grid into the asphalt and make the pattern.

They were working on Charles/Queen tonight, so I get to correct/improve my description:

1. Mark the positions on pavement
   
2. Apply some goop (technical term!) on the crosswalk area
   
3. Place coloured polymer tiles (roughly 60x60 cm) on the crosswalk area, in the desired colour pattern
   
4. Press down to adhere
   
5. Heat the polymer and underlying pavement
   
6. Place the grid on the polymer tiles, appropriately aligned with the colour edges
   
7. Use compactor to press the grid into the pavement, to make the brick pattern; the polymer will stretch to cover the indents/grooves
   
8. Remove the grid
   
9. Let cool
   
10. Done!
