Frequently Asked Questions (FAQ)

What are the main differences between the two specimen sizes?
The standard method produces 101.6mm x 87mm specimens for regular Marshall tests, while the large-scale method produces 152.4mm x 115mm specimens for specific testing requirements.
Is the compaction count handled manually?
No, the Electric Marshall Compactor features an automatic recording system and a preset function (0-99 times) with memory storage.
What material is used for the compaction table base?
The base consists of a steel plate on a hardwood block (oak, pine, etc.) with a dry density of 0.67-0.77 g/cm³, secured to the base plate.
What are the power requirements for this equipment?
The equipment operates on a 220V ± 10% 50HZ power supply with a power consumption of approximately 370W.
How is the temperature monitored during the mixing process?
Temperature can be monitored using an infrared thermometer or a thermocouple asphalt thermometer with a metal stem at least 300mm long, covering a range of 0-300°C.
Are the test molds durable enough for repeated use?
Yes, the test molds are manufactured from high-carbon steel or tool steel to ensure durability and precision during high-frequency compaction.
