Type of joint Example / Details use Subjective advice Remarks
placed
Bituminous joint
Reported under “flexible plug
joints”
Old type of joint.
The gap was bridged by a
copper sheet
Flexible plug joints "Thorma" Only used for joint
replacements when movement
capacity needed is less than 30
mm
Buried joints Joint under the road surfacing
with reinforcement
Finger joints Finger joint with watertight
neoprene membrane under
finger plate
Mat joints Rubber joints "(GHH -
"Transflex")
Not used nowadays Cracks appear systematically
in the road surfacing when the
movement capacity needed is
a little important.
Fairly good behaviour
Sometimes cracks appear in
the adjacent road surfacing
when a new joint is combined
with an old pavement.

Easy repair
Difficulties appear at the uplift
of the extremity to avoid the
flowing of water.
Life cycle cost are relatively
high due to frequent
maintenance. Joints have to
be replaced with replacement
of pavement adjacent to
joints.
One test No experience Difficulties appear at the uplift
of the extremity to avoid the
flowing of water.
Have been often used in the
past but not used nowadays
Seldom placed (Pont des
Ardennes)
Good resistance of the joint it
self but the watertight
membrane finishes by splitting
due to the accumulation of
dirt.
Generally good behaviour
with actual joints.
Watertightness problems at
the boundary between the
joint and the road surfacing.
Sensitive to wear.
Broken fingers in aluminium
alloy (Quality of the
aluminium alloy ?)
Dangerous for motor cyclists
In the passed, bad experience
with the type made in Belgium
due to the lack of wear
resistance of the rubber.
