Adaptive temperature	Ordinary type:+80ºC--25ºC
	Hardy type:+80ºC--45ºC
Scope of application	Old bridge replacement and new small bridge and the opening of the bridge.

\ n \ n \ n \ n II \ n Q: Quelles sont les caractéristiques du joint de dilatation en caoutchouc? \ n A: Il y a les caractéristiques du joint de dilatation en caoutchouc:

i  It can freely flex in parallel and vertical direction.

ii  It is firm and reliable.

iii  It is smooth, no sudden jump and noise when the vehicle passes by.

iv It is waterproof and it can prevent the infiltration of debris into the block.

v It is convenient for installation, inspection, maintenance, removal of dirt.

\ n \ n \ n \ n III \ n Q: Comment classer le joint de dilatation en caoutchouc? \ n A:

1. Slab type expansion jointIt is made of rubber, vulcanized or steel plate.It is suitable for ordinary highway bridge engineering which the expansion volume is less than 6Omm.

2.Combined expansion jointIt is made of rubber plate and steel plate.It is suitable for ordinary highway bridge engineering which the expansion volume is less than 120mm.

3. Modular expansion jointIt is composed of the whole shaped steel.And it is composed of the side beam, the middle beam, the beam, the displacement control system, the sealing rubber belt and so on.The advantages of it are good integrity and high bending and compressive strength.There is smooth and no jump and low noise when the vehicle passes by.It applies to all kinds of bend, slope, oblique, wide bridge.Displacement design of modular expansion joint can arbitrary group according to the actual needs.
