B049, ASPHALT TESTING APPARATUS

Λεπτομέρειες
Κατηγορία: Ασφαλτικά / Bitumen - Asphalt

Standard:
ASTM D4123 -BS598:111 -BS DD 213,DD226
Description: This apparatus is a general purpose testing machine developed to carry out a range of tests on asphalt.
The emphasis has been on producing affordable systems with the versatility to perform both routine testing and detailed research investigations. The MATTA is based on a simple reaction frame comprising a steel base plate, support columns and crosshead. Cylindrical samples are positioned between the base plate and the crosshead, and an electro-pneu-matic actuator is used to exert dynamic compressive forces.
Measurement of displacement and forces enables the resultant stress and strain in the sample to be determined.
Jigs are provided to allow axial or diametral (indirect tensile)loading of samples. The machine is controlled by a compact microprocessor based Control & Data Acquisition System (CDAS).
All time-critical parameters are controlled directly by the CDAS unit for reliability and accuracy. A temperature controlled cabinet is available (accessory) where accurate control of test temperature is required,as is the case when testing asphalt.
