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 Features

Auto data logging software available which:
- Reduces operator involvement
- Eliminates chances of error
- Generates graphical representation of the test in real time
- Saves operator data, sample information data, time, and pertinent information relevant to the specific sample on test
- Reduces test costs significantly
Heater element to comply with both temperatures requested by EN standard
Stainless steel
Temperature controlled water bath with drain facility
Digital indicator with digital communications.
CE Marked and Made in United Kingdom




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.
*Additional function allows the user to input a temperature between 5°C (or ambient if higher) and 95°C.
