It is sometimes desirable to dilute an emulsified asphalt in the field with water. This practice is designed to ascertain if this may be done safely without breaking the emulsified asphalt.

Note 2—Water supplies available in some areas contain high levels of dissolved salts and other minerals which coalesce emulsified asphalts to a greater degree than distilled or deionized water. It is recommended that the user evaluate potential local water sources using this practice before attempting a field dilution.

1. Scope

1.1 This practice covers all medium and slow-setting emulsified asphalts. It is not applicable to the rapid-setting types.

1.2 This practice 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.
