1General provisions
1.1Scope
The “Additional technical terms of contract and guidelines concerning joints in traffic areas”, 2011 edition [German designation: ZTV Fug-StB], deal with the establishment of joints in traffic areas in connection with new building and maintenance measures and for airfield fortifications. They especially apply in conjunction with the Additional technical terms of contract and guidelines for the construction of roadbases containing hydraulic binders and concrete carriageway surfaces, the Additional technical terms of contract and guidelines for the structural upkeep of road surfaces – concrete constructions, the Additional technical terms of contract and guidelines concerning the construction of traffic area fortifications from asphalt, the Additional technical terms of contract and guidelines concerning the structural upkeep of traffic areas - asphalt constructions, the Additional technical terms of contract and guidelines for the construction of sett and slab pavements and kerbs, the Additional technical terms of contract and guidelines for the corrosion protection of steel structures and the Notes on the closing and reparation of cracks and defective seams and seals in traffic areas.
The Additional technical terms of contract and guidelines concerning joints in traffic areas regulate joint filling systems which, depending on the joint filling compound chosen, have to absorb variations of up to 7 mm in the joint gap width by way of movements. With larger movements, joint structures must be executed as carriageway transitions, for instance.
The Additional technical terms of contract and guidelines concerning joints in traffic areas shall be applied in conjunction with the “Technical terms of delivery for joint filling compounds in traffic areas”, 2011 edition [German designation: TL Fug-StB].
This set of regulations shall not apply to installations which are covered by the special regulations under law concerning the containment, filling and handling of water-endangering materials and those covered by the special regulations under law concerning the preparation, treatment and use of the same.
The Additional technical terms of contract and guidelines concerning joints in traffic areas take into account the fact that the German construction contract procedures - Part C: General technical specifications in construction contracts (ATV) and, in particular,
ATV DIN 18299General rules applying to all types of construction work,
ATV DIN 18316Road construction - Surfacings with hydraulic binders,
ATV DIN 18317Road construction - Asphalt surfacings, and
ATV DIN 18318Road construction - Dry jointed sett and slab pavements, and surrounds
form part of the building contract.
The paragraphs in this text which are indicated by a line in the margin are “Additional technical terms of contract” within the meaning of Section 1 point 2d of the German construction contract procedures - Part B (DIN 1961), where the Additional technical terms of contract and guidelines concerning joints in traffic areas constitute part of the building contract.
The paragraphs in this text which are printed in i t a l i c s, and which are not indicated by a line in the margin, are “Guidelines”. They must be observed by the Client when drawing up the specification of works and when monitoring and accepting the building works.
Provision can be made for the joint fillings and/or joint filling systems described in the Additional technical terms of contract and guidelines concerning joints in traffic areas in connection with new building and maintenance measures on all traffic areas for moving and stationary traffic.
As regards particular areas of application, such as for special chemical stresses, suitability must be verified on a case-by-case basis.
In the case of maintenance measures, the nature and extent of the contaminant levels in the materials being removed must be indicated in the specification of works.
Paragraphs in small print refer to sections in the German construction contract procedures - Part B, or to chapters in ATV DIN 18316, ATV DIN 18317 and ATV DIN 18318.
Products and goods originating from other Member States of the European Union, or Turkey, or from an EFTA State which is a signatory to the Agreement on the European Economic Area, which do not conform to these Additional technical terms of contract, shall be regarded as being equivalent, including the tests and inspections conducted in the country of manufacture, provided that the required level of protection in terms of health and safety and the product being fit for its purpose is achieved in the same permanent manner.
The abbreviations used and the technical regulations indicated in the text are summarised in Annex B.
1.2Terms and definitions
The following definitions are applicable to joints in road surfaces:
Alteration of the joint gap width: joint openings or movements at structural component temperatures of between -20 °C and +60 °C. In the event of continued displacement of the concrete slabs, they relate to the original joint gap width.
Bituminous water stop: preformed, thermoplastic strip profile containing bitumen which is melted to layers of asphalt through the supply of heat. It may contain additives of synthetic materials, plasticisers and mineral fillers.
Joint insert: structural element incorporated for the purpose of establishing expansion joints which partially remains in the joint insert or is removed in its entirety.
Joint filling compound: generic term for all materials inserted into the joint gap and the combined effect of which represents the joint filling system.
Joint filling system: combination of underfilling material, primer and joint sealant which seals the joint gap in a durable manner.
Joint notch: predetermined breaking point in a concrete slab; brings about the targeted tearing of the dummy joint; expands as far as the joint gap in the upper area.
Joint sealant: hot or cold applied joint sealant which is inserted into the joint gap.
Type N1 as per the Technical terms of delivery for joint filling compounds in traffic areas: thermoplastic bituminous compound applied hot which is predominantly elastic.
Type N2 as per the Technical terms of delivery for joint filling compounds in traffic areas: thermoplastic bituminous compound applied hot which is predominantly plastic.
Class 25 and 35 as per the Technical terms of delivery for joint filling compounds in traffic areas: reactive single- or dual-component system with elastic properties which is applied cold.
Joint seal: compressible elastic seal which is inserted into the joint gap.
Joint gap: (also: joint cavity): space in which the joint filling compound is placed. An incision is made with dummy joints, working joints and expansion joints.
Slip joint: separates the slabs from one another across the entire thickness of the pavement and facilitates a longitudinal displacement of the slabs (to prevent reflective cracks in the case of transverse joints that are offset against one another) by means of an insert.
Paving and rail joint sealant: thermoplastic compound mainly consisting of bitumen in the form of binding material.
Working joint: separates the structural component and the slab from one another across the entire thickness; in contrast to the expansion joint, does not provide any room for the concrete to expand beyond its original length.
Expansion joint: separates the structural component and the slab from one another across the entire thickness of the pavement and enables both to expand by means of a broad, preformed joint gap.
Crevice sealer: thermoplastic compound mainly consisting of bitumen in the form of binding material which is primarily used to backfill cracks.
Dummy joint: predetermined breaking point in the concrete slab which is established by notches in the top of the pavement.
Protective lining: solid or closed pore elastomeric or plastomeric membrane which prevents the infiltration of dust, sludge or foreign bodies into the emerging crack.
Underfilling material:
preformed profile incorporated into the joint gap which seals the latter at the envisaged grouting depth and prevents three-sided adhesion and/or infiltration of the joint sealant into the indentation with the existing joint notch.
For certain applications, a separating strip is inserted in place of the underfilling material.
Primer: substance which supports joint sealant adhesion along the joint edges.
Permissible total deformation: (abbreviation: PTD) The permissible total deformation is the deformation range (sum total of expansion, compression and shear as a %) within which the joint sealant maintains its functionality.
1.3General principles
1.3.1Limit values and permissible variations
The limit values and permissible variations specified in the Additional technical terms of contract and guidelines concerning joints in traffic areas cover both dispersion during sampling and the confidence ranges of the test methods (precision under comparable conditions), as well as the irregularities associated with working, unless another provision is laid down in a particular case. The permissible variations for the joint filling compounds are stipulated in Annex A. The permissible variations regarding the execution of construction work are stipulated in the individual sections.
1.3.2Nature of the tests
Refer to DIN 18316, Sections 2 and 4, and DIN 18318, Sections 2 and 3.
1.3.2.1General provisions
Original inspections
The Contractor shall present the Client with the test results established within the framework of the original inspection as per the Technical terms of delivery for joint filling compounds in traffic areas and declare suitability in good time prior to building work starting.
The tests conducted within the framework of building construction fall into the following categories:
–internal quality control tests,
–check tests,
–additional check tests,
–arbitration investigations.
Insofar as is necessary, the tests include the following:
–sampling,
–packing the sample, ready for dispatch,
–transporting the sample from the withdrawal point to the test centre, and
–analysis, including a test report.
As regards sampling and testing for the purpose of proving the quality characteristics of the building materials, the methods indicated in the corresponding technical regulations shall apply.
1.3.2.2Internal quality control tests
The following constitute internal quality control tests:
-inspections of incoming building materials,
-tests carried out at the time of delivery,
-tests carried out at the time of execution.
Internal quality control tests are tests carried out by the Contractor, or his authorised representative, during the execution of construction work to establish whether the quality characteristics of the joint filling compounds supplied (tests performed on the building materials) and the finished work (tests carried out at the time of execution) satisfy contractual requirements and comply with the data from the original inspection.
The Contractor (processor), or his authorised representative, shall perform the internal quality control tests with the necessary care and to the extent laid down in Annex A. If deviations are established, the Contractor shall immediately take the necessary corrective measures. Only those building materials which satisfy requirements may be used.
The results of the internal quality control tests must be presented to the Client on request.
1.3.2.2.1Inspections of incoming building materials
Inspections of incoming building materials are tests carried out by the Contractor (processor) on the joint filling compounds supplied in order to determine whether they satisfy the contractual requirements of the applicable technical regulations in terms of type and quality. The performance of inspections on incoming building materials presupposes recognition, in accordance with the Guideline for the recognition of testing bodies for building materials and mixtures thereof that are used in the field of road construction, of the laboratory used by the Contractor (processor) or his authorised representative for joint filling compounds.
Inspections on incoming building materials must be performed in accordance with Annex A for every joint filling compound used.
Performance of the tests as per Annex A shall lapse if the Contractor (processor) has a certificate from the manufacturer concerning quality monitoring, the content of which is equivalent to the scope of the test laid down in Annex A. In this regard, the inspections performed within the framework of this quality monitoring must be carried out by an independent test centre which is recognised in accordance with the Guideline for the recognition of testing bodies for building materials and mixtures thereof that are used in the field of road construction.
