Standard Practice for
Use of Portland Cement Concrete Bridge Deck Water Barrier
Membrane Systems1
This standard is issued under the fixed designation D 4071; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. 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.
2. Referenced Documents
2.1 ASTM Standards:

3. Terminology
3.1 For definitions of terms used in this practice, refer to
Terminology D 3743.
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
