COOPER Indentation Testing Machine

Introduction

The Indentation Testing Machine CRT-IND for determining the resistance to penetration of road and mastic asphalt by loading a cylindrical pin and measuring the indentation in a sample over a given time. The CRT-IND comprises of a frame incorporating a stainless steel water bath with drain facility, method of applying the 500 Newton load and means of recording the test results.* Immersion heater is not included but can be offered as additional equipment. The apparatus conforms to the requirements of EN 12697-20.The maximum nominal size of the aggregates should be less or equal to 16 mm. It comes with optional auto data logging software which saves test data files, shows a graphical representation of the test in real time, reduces operator involvement and thus eliminates chances of error.

Key Use

  • Determines the depth of indentation.
  • To test the behavior of mastic asphalt, rolled and other such asphalts

Software

  • CRT-INSOFT, A Cooper Technology designed and developed software package that allows for the automatic capture to PC of test data from the indentation test at the two required test temperatures* and over the four time durations. This software shows a graphical representation of the test in real time, storing the data in text files that can subsequently be opened in Excel.
