T-SQL (SS2K8) :: Merging Intervals With Identical Data

I'm having issues building a cte sql statement for merging intervals. I have a table with data as follows:

declare @table table
(
startpoint int,
stoppoint int,
value int
[Code] ....

The resulting query returns the rows in the table, sorted by startpoint:

startpoint stoppoint value
----------- ----------- -----------
0 10 1
10 15 1
15 25 2
25 30 2
30 40 2
40 55 3
55 60 3
60 80 2

I'm looking for a merge cte that returns consecutive intervals with the same value, as follows:

startpoint stoppoint value
----------- ----------- -----------
0 15 1
15 40 2
40 60 3
60 80 2
