Good morning! How do you conduct the determination of the exact lowest percentage of xylene that produces a negative spot for AASHTO T 102? Thank you.

How to prepare 20-25% xylene-heptane?

Hi Infinity
In this test, Can we use hexane instead of heptane?

[@InfinityGalaxyCo]

No, you can't. Solvents play an important role in this test so you should conduct it exactly as per standard procedure
