Specifications

Digital Control Electric Compaction Tester is a new microprocessor controlled intelligent heavy electric compaction tester

Purpose
The instrument is designed and made as per T0131 “Compaction Test Standard” in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is used for light compaction test or heavy compaction test in the highway construction.
The instrument is a new microprocessor controlled intelligent heavy electric compaction tester. It has characteristics of delicate, beauty, operation convenience, running stability and reliability, automation, strong anti-interference ability, and convenient maintenance. It is a advanced, practical, and desired instrument for highway construction test.
Instrument function:
1. The default mode for counting is countdown;
2. It has function of inching movement, so you can determine the rotary direction of motor;
3. You can modify or preset compaction times;
4. It can be reset manually;
5. It has function of pause. It does not affect compaction times if it halts during a test.
