No sure if I understood what you asked but here we go.
First I'd rescale (r.rescale) the aspect to the desired directions.
Take a look at the r.slope.aspect man page [1] to see what the aspect
values represent
Then I'd rescale the directions map to the weights you mention.
Hope it helps

I need to rescale an aspect map in a scale 0-255 where North = 0 and SE=255.
Finally I need to assign weights as follow:
0.02N
0.02NE
0.12E
0.34SE
0.20S
0.18SW
0.08W
0.03NW
Thank you!

But the output file has a range 60-255
What's going wrong?
