Asphalt Testing for Any Situation

From Aggregate to Asphalt Performance Testing, AMS is capable of providing all of your aggregate and asphalt testing. AMS regularly partners with other AASHTO accredited laboratories so that we can ensure that our clients are provided with quality data for any job.

Picture

Cracking Potential

We provide in house testing for I-FIT, IDEAL and SCB testing. We also can provide low-temperature IDT, OT and DCT.
Picture

Moisture Damage

TSR testing of dense and open-graded mixtures along with the Boil test for determining the affinity of asphalt binder and aggregate.
Picture

Rutting Susceptibility

The APA Jr. is capable of evaluating rutting, fatigue cracking and mositure sensitivity of asphalt in wet and dry conditions.
