ตัวทดสอบความหนาแน่นขนาดใหญ่สำหรับคอนกรีตยางมะตอยอัดแน่น

Suitable for:
Construction, Geological Exploration, Roadway research lab
 
Principle:
 
In accordance with the standards of GB/T2413, 1966, 2834, ASTMC20/C134/C373/C329, EN-725-10, AASHTO T166, ASTM D6572, T0705, and by adopting the buoyancy method of Archimedean principle, the boiling water method, wax-sealing method, vacuum saturation method and surface dried method can be chosen to use, it can show the measuring result accurately and fast.
 
Specifications:
 
 
Functions:
 
*The machines can directly show the bulk density ( Gmb ), apparent porosity, wet density, volume of compacted asphalt concrete.
 
*When water absorption of product is higher than 2%, the bulk density can be showed by using wax-sealing method.
 
*The machines have the function of water temperature and solution compensation, density setting when using wax-sealing method
 
*By adopting the design of big tank, it can decrease the inaccuracy caused by supporting wire's buoyancy.
 
*Standard size of water tank: 150×100×90mm.
