In areas where different materials connect or join onto asphalt surfaces that have already cooled, no watertight and permanent connections are produced without any further measures. According to ZTV Asphalt-StB, seams and connections must therefore be sealed with corresponding systems when producing asphalt coverings.
CREATING WATERTIGHT CONNECTIONS.
APPLICATION
Protection of the substructure against erosion
Safe absorption of movement through joint in appropriate width
For composite construction, raising of joints in the asphalt surface to absorb movement
SERVICES
Construction of seams and joints in asphalt according to ZTV Fug-StB and ZTV Asphalt-StB
Cutting and sealing connecting seams and structural joints
Filling joints in front of kerbs according to RiZ DICHT 9
Raising joints in the asphalt with superstructures on over concrete roads (e.g. in DSH-V)
Also chemically stable construction in storage, filling and handling plants and on WHG surfaces
Cutting the joint
Constructed joint chamber
Sealing the joint
Finished joint in DSH-V on concrete
CONSTRUCTION
Cutting with joint cutter (dry or wet cut with extraction)
Cleaning the joint using a brushing machine or compressed air
Applying the bonding agent, if necessary
Version with and without undersealing
Melting the joint material in indirectly heated melting cookers
Inserting the sealant using lances
ADVANTAGES
Selection of suitable materials adapted to the intended use
Cost-effective increase of the service life and value preservation of the infrastructure due to professionally designed joints with high-quality filling materials
Absorption of movement in the joint – preventing cracks
