SYD-0711A Asphalt mixture theory of maximum relative density tester

Brief introduction

Asphalt mixture is suitable for vacuum method, the theory of maximum relative density, for the mix proportion design of asphalt mixture, road survey or pavement construction quality management calculation used void ratio, degree of compaction, etc.But shall not apply to the bibulous rate is more than 3% of porous asphalt mixture of aggregate.

Features

1. Using single-chip microcomputer control technology, vacuum, pressure, vibration, fill gas automatically.

2. Absolute pressure sensor with high precision, instrument negative pressure container pressure of 3.7 kPa + / - 0.3 kPa.

3. Equipped with vacuum table, can directly reflect the performance of the vacuum pump.

4. Containing water buffer device, can prevent the negative pressure of the water in the container into the vacuum pump.

5. Can be two parallel test samples at the same time, reasonable structure, convenient use, high efficiency.

Technical parameter

1. Power supply voltage: AC (220 + / - 10%) V, 50 hz;    

2. Container volume: 4000 ml x 2.

3. Vacuum pump power: 160 w;

4. Negative pressure container pressure: 3.7 kPa (27.75 mmHg), allowable deviation plus or minus 0.3 kPa;

5. Motive power of vibration: 30 w;                

6. Appearance size: 510 mm * 520 mm * 380 mm (length x width x height).
