ASTM D4071-84(2016)
(Practice)Standard Practice for Use of Portland Cement Concrete Bridge Deck Water Barrier Membrane Systems
Standard Practice for Use of Portland Cement Concrete Bridge Deck Water Barrier Membrane Systems
SIGNIFICANCE AND USE
4.1 This practice provides a guide for factors to be considered prior to waterproofing bridge decks with water barrier membrane systems. It will provide guidance for specification of materials, application of membrane systems, and placement of bituminous wearing courses. It may be used as a guide for new construction or for rehabilitation of existing structures.
SCOPE
1.1 This practice covers liquid applied, preformed, or built-up water barrier membrane systems and their application; overlaid with bituminous concrete wearing courses, for use in the protection of bridge decks from deleterious effects of deicing salts. Material use and specifications should be adapted to conform to job and user requirements for new construction or existing structures. This practice is written as a guide for the use of bridge deck water barrier systems only.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 10.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

4. Significance and Use
4.1 This practice provides a guide for factors to be considered prior to waterproofing bridge decks with water barrier membrane
systems. It will provide guidance for specification of materials, application of membrane systems, and placement of bituminous
wearing courses. It may be used as a guide for new construction or for rehabilitation of existing structures.
5. Bridge Design and Specification Consideration
5.1 Proper use of water barrier membranes with bituminous concrete wearing courses requires consideration of certain elements
during the design stage of new or existing bridges to be treated and covered with a bituminous concrete wearing course.
5.2 New bridge deck designs must include provision for dead loads including future systems.
5.3 The deck surface finish should be specified to allow proper use of the intended membrane system. Manufacturers’
recommendations for surface finish should be reviewed for guidance on finishing freshly placed concrete or for repair of existing
deck surfaces.
5.4 Surface drains should be designed to allow positive drainage to minimize the penetration of water through the bituminous
wearing course.
This practice is under the jurisdiction of ASTM Committee D04 on Road and Paving Materials and is the direct responsibility of Subcommittee D04.32 on Bridges and
Structures.

D4071 − 84 (2016)
5.5 Joint systems should be designed to provide adequate termination points for the membrane. Membranes should not be
placed over expansion joints. Dams or expansion assemblies should be provided to the height of the bituminous wearing course.
5.6 Curbs or parapets, or both, should be designed for functional terminations. Manufacturers of membrane systems should be
consulted for recommended termination details. If rough surfaces (such as granite curbs) are specified, a treatment should be
specified to provide the surface smoothness required for the proper use of the membrane. Treatment of rough curbs may be
achieved with a leveling surface treatment with epoxy mortar or other suitable materials.
5.7 Decks should include weepholes to provide drainage for water which penetrates through the bituminous wearing course to
the membrane level.
5.8 For bridges with significant grades (usually over 4 %) or those which are subject to traffic acceleration, deceleration, or
radial stresses (such as on ramps), the use of membrane systems may cause overlay movement. Membrane manufacturers should
be consulted for limitations on membrane use.
5.9 Service life and maintenance requirements should be considered when designing the water barrier and wearing surface.
5.10 Specified materials should be chemically and physically compatible with specific emphasis on proper adhesion of the
membrane and the bituminous wearing course.
6. Bridge Construction
6.1 A preconstruction conference should be held to assure that the contractor is aware of all construction requirements which
affect the membrane system.
6.2 Inspectors should ensure that surface finish of the concrete deck is acceptable for the use of the intended membrane system,
usually an even float finish.
6.3 Concrete decks or other components should be cured and dried for the required minimum time before installation of the
membrane. Limitations on curing methods or curing materials should be observed. In most cases, the use of membrane curing
compounds containing wax or oil should be prohibited.
6.4 Care should be exercised to avoid the use of materials which are chemically or physically incompatible with the membrane
system to be used.
7. Membrane Application
7.1 A preconstruction conference should be held to schedule membrane application and placement of the bituminous wearing
course.
7.2 Prior to application, the bridge deck should be inspected, deficiencies no
