Definitions

  • the invention relates to a joint profile, in particular for joints in road surfaces, as well as a road surface system.
  • concrete pavements are generally used for the road surface. These offer greater stability and durability, for example compared to asphalt.
  • Such concrete covering layers are typically around 18 to 30 cm thick and consist of several concrete slabs, which can be connected to one another with dowels and/or anchors, for example. Temperature fluctuations, moisture and/or loads can lead to different movements of adjacent sections of the concrete slabs, which can cause stress cracks.
  • joints particularly longitudinal joints and transverse joints, in the concrete covering layers.
  • dummy joints can be used which do not completely cut through the concrete slabs and serve as a predetermined breaking point in the form of joint notches to enable controlled crack formation.
  • the joint notches can be widened by cutting them open to form a joint gap.
  • the joints are usually filled with a sealing material. Joint profiles are used for this purpose, for example.
  • the joint profiles must meet high requirements. On the one hand, they must ensure that the joints are sealed against the ingress of water and/or moisture and the pollutants dissolved in them in order to prevent the resulting erosion of the lower supporting layers and the breaking of road slabs. The accumulation of foreign bodies in the joints should also be prevented and the joint profile itself should have sufficient flexibility or deformability. Otherwise, for example, the mobility of the concrete slabs could be restricted. This could lead to cracks, edge breaks and/or slab breaks. Finally, the joint profiles should be able to retain their properties for as long as possible and the joint profiles should reliably not sag or tear out of the joints. The joint profiles must be able to withstand traffic loads, temperature fluctuations up to extreme temperatures of e.g. -20°C to +50°C, moisture from water vapor and rain as well as horizontal joint movements, e.g. quasi-static, i.e. slow, up to 7 mm and dynamic up to 0.1 mm.
  • the WO 03/046300 A1 shows a seal having a main web from which first and second side arms protrude.
  • a first connecting web extends between a first of the side arms and a second of the side arms, such that a first cavity is enclosed by the first side arm, the second side arm, the first connecting web and the main web.

  • the joint profile is in particular a profile element.
  • the joint profile can advantageously be designed in one piece and/or essentially in one piece. "Essentially in one piece” can mean, for example, that one or more components, such as an anti-stretch thread, are incorporated or embedded in the joint profile.

  • An end of the joint profile that closes the joint profile in the positive longitudinal direction is referred to as the first end, while an end that closes the joint profile in the negative longitudinal direction is referred to as the second end.
  • the deviation can be, for example, a deviation in an extension length, an angular orientation or a curvature (based on the ratio of the curvature to the width or wall thickness of the component).
