Air Enterained test by Air Indicator Kit:

This kit provides a quick and easy method to check air content. A sample is placed in the vial and alcohol is added to free the air. The change in level of the alcohol in the vial stem indicates the air content. The test takes about 3 minutes to perform and is therefore ideal for field use at either a pour site or batch plant. It may also be used to determine whether more thorough testing may be needed. The open end of the vial has a reinforced lip and extra graduation marks are included on the stem. The kit includes a vial with stopper/cup, squeeze bottle for alcohol, brush and instructions in a plastic case. Applicable Standard: AASHTO T-199
