Having driven that sandy road the past 2 days a few times, I can safely say that the road is dangerous, with ridges of sand, and it should be "broomed" with the broom contraption that is just lying on the side of the road about 3 k's out from camp on the right hand side. :thumbs_up:



Have to agree with you here Scips seeing that we drove that road quite a few times when we were up at letaba in June it is dangerous :big_eyes:

The tar roads in Kruger are constructed and maintained using a process of "sand sealing".

Refer to the linked pdf below for a in depth discussion:

This does seem to explain most of the instances where I have seen sand covering the tar roads.

What I have also found interesting is that the sand remains on the tar for a long time after. I have been on a trip and seen them doing the road works, and driven on the 'freshly' laid sand, then returned a good while after, to find the road still has sand on it.
