Marshall electric compaction instrument
Marshall electric compactor is an extremely important testing instrument in the field of road engineering. It is mainly used to make asphalt mixture specimens, and obtains standard asphalt mixture specimens by simulating the compaction effect of a road roller during actual road construction. These specimens can help engineers and researchers evaluate the physical properties of asphalt mixtures, such as density, porosity, etc., providing key data for road design, construction quality control, and optimization of asphalt mixture formulations.
In road construction, the compaction degree of asphalt mixture directly affects the strength, durability, and smoothness of the road surface. The Marshall electric compactor is like a small compaction factory, which uses precise compaction operations to achieve the expected dense state of asphalt mixture, just like in real road construction scenarios, by tightly arranging the particles of the mixture to simulate the actual compaction situation of the road.
Brief introduction:
When the rammer reaches the required height, the pawl releases the rammer, which falls freely on the test specimen. The release mechanism is connected by an arm moving up and down, which is connected to a reduction gear coupled to the motor through another arm. An automatic Electronic blow counter is used to set the desired number of blows. The Compactor is supplied complete with wooden pedestal. Suitable work on 230 V, 50 Hz, Ac Single Phase.
Basic structure:
It consists of two parts: the compaction hammer and the standard compaction table.
The compaction hammer is composed of mechanical transmission and electrical control, which can realize functions such as automatic counting, automatic compaction, and automatic shutdown.
