First Simple Performance Testers Delivered
 
This summer, Interlaken Technology Corp. (Eden Prairie, MN) and Shedworks Inc. (College Station, TX) delivered the first models of a new device that can perform three simple performance tests designed to give contractors and road-building agencies extra confidence in the rut- and crack-resistance of mixes that meet volumetric mix design criteria. Production of the equipment is an important milestone in the NCHRP/FHWA-funded research program to develop a simple performance test for the Superpave system. The device is designed to conduct three tests that were identified under NCHRP Program 9-19:

--  Creep Test (tests rut-resistance)
--  Repeated Load Test (tests rut-resistance)
--  Complex Modulus, Frequency Sweep Test (tests rut- and fatigue crack-resistance)
