Описание
Значение и использование

3.1 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 without irreversibly separating the water and asphalt (breaking) in the emulsified asphalt.

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

1.1 This practice covers the suitability of all medium and slow-setting emulsified asphalts to be diluted with water.. 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.
