Specifications
Interlaken serves the Asphalt testing market with the Superpave Direct Tension Tester (DTT). This unit evaluates the low temperature thermal properties of asphalt binder. The Interlaken DTT has been evaluated by the Federal Highways Administration and meets all AASHTO, SHRP, and FHWA specifications. It is designed to perform asphalt binder tests in accordance AASHTO T 314 and ASTM D 6723 test protocols. The DTT features both the simplicity required of a routine specification tester for QA/QC and the versatility of a full research instrument. In fact, it’s just as easy to determine the Pass/Fail analysis for asphalt Performance Grading as it is to perform comparisons of binder/additive and binder/modifier interactions over a wide range of strain rates. The system performs the Direct Tension test, and with optional tooling a Blister test and an Adhesion test.
