Grahame (once again!) makes a very valid point=20
What PSV are the designers predicting for the proposed surface?
For any reasonable traffic flow DMRB would lead to an expectation of 65+

We were not aware of any requirement to use thermoplastic, just that a
(white) stop line to diag 1001 (TSRGD) should be installed.
We have used white sticky road marking tape and even spray paint so
cannot see any reason why white granite blocks would not suffice.
The legality as we see it lies in the dimensions, the location and the
alignment. Hope they get it right first time !
However, wet granite is not the first material we would think of with
adequate skid resistance.

We are replacing an existing traffic signal control installation within
our city centre. A significant investment in materials is to be made as
the final scheme will figure centrally in our public realm. Granite
will be used in the carriageway construction and we are seeking
alternatives to thermoplastic to define the signal controlled stop
lines. The possibility of a contrasting white granite has been tabled
as an option. I'm aware of the relevant BSI that lining materials must
adhere to and tolerances on stopline widths etc, but the alternative of
thermoplastic on granite is not entirely attractive.
Has anyone used anything other than thermpolastic to deliniate stop
lines at traffic signal control junctions in public realm schemes?
