This laboratory instrument is known as GMM Apparatus and it is used for accurate assessment of the bulk specific gravity (Gmm) of asphalt mixtures. This equipment as part of the essentials for all material testing laboratories helps to determine the accurate results that are reliant on superior technology and structures. In quality control or research on asphalt production, GMM Apparatus provides the performance you require for accurate outcomes.
Especially suitable for the asphalt mixture testing laboratories, the GMM Apparatus supplies valuable information concerning the performance and durability of pavements. As a matter of fact, it is one of the most effective tools needed to help maintain high quality throughout the construction and development of roads, and highways.
Some of the features of the GMM Apparatus include the following;
- Vacuum Pycnometer: The GMM Apparatus is shipped complete with a vacuum pycnometer output with volumes of 4. For example, the company may need to perform tests on different amounts of liquid ranging from 5 liters to 10 liters at times, for that it needs to have them available. The pycnometer helps in getting rid of the bubbles of air that may interfere with determination of the specific gravity.
- High-Performance Vacuum Pump: The apparatus comprises of a very efficient 2-stage vacuum pump which has the capacity to pull out air with a pulling capacity of 2. 5 – 6 CFM or 169 L min. In addition, the presence of a reliable 3/4 HP motor which delivers adequate force to drive the pump facilitates timely removal of air hence accuracy in tests derived from it.
- Vibro-Deaerator: In order to increase the precision of the results, the GMM Apparatus has a vibro-deaerator incorporated in the system that utilizes a vacuum timer system to eliminate the entrapped air by vibrating the sample. This additional feature helps to avoid air pockets and stabilises and increases reliability in the rates of GMM.
The GMM Apparatus also has several advantages:
- Accuracy and Consistency: That is why GMM Apparatus has such advanced features as vacuum pycnometer and vibro-deaerator to provide more precise and consecutive measurements and that is why it is popular among laboratories.
- Time Efficiency: This is made possible by the integration of the vacuum pump and the timer controlled vibro-deaerator which takes shorter time to remove air from the samples hence making possible faster tests without compromising on the accuracy.
- Versatility: Based on the size of the samples that have been used, the GMM Apparatus covers different sizes to fit different testing requirements.
