Overview

The manual railway ballast aggregate impact toughness testing machine shall comply with the standard TB/T2140.2-2018 "Testing Part of Railway Crushed Stone ballast". The impact index of the standard aggregate impact toughness testing machine represents the parameter of the ballast material's resistance to instantaneous impact or impact. Value test is used to determine the recommended standard aggregate impact toughness testing machine by the China Academy of Railway Sciences for road surfaces; #160; Aggregate impact toughness testing machine for ballast inspection. The impact resistance of coarse aggregate is expressed as the mass percentage of the portion less than 2.36mm after crushing.
