Moss on tarred road

My driveway was retarred 3 years ago and now there is green moss appearing all over it. I previously removed some with boiling water but the area would take forver. Any ideas what's best to remove, thanks, R

 

I water soda crystal solution on mine but will be interested in other remedies

 

I used diluted Jeyes Fluid on my shed to remove moss, it worked a teat.

 

My Neighbour swears by 'Wet and forget' and I must say it's worked a treat.
