Automatic Marshall Compactor 295 kg Manufacturer,Supplier and Exporter in India
Product Code : TVT-BATE-10339
The Automatic Marshall Compactor 295 kg from Tvet Equipments is a motor-driven compaction unit built to prepare bituminous mix specimens for Marshall stability and flow testing without the fatigue and inconsistency of hand compaction. A digital stroke counter halts the hammer automatically once the preset number of blows is delivered, so every specimen in a batch receives an identical, repeatable compactive effort.
How It Works
The compaction mould holding the heated bituminous mix specimen is clamped beneath a free-falling rammer weighing 4535 ± 15 g, which drops from a fixed height of 457 ± 5 mm onto the specimen face. A geared motor lifts and releases the hammer at a controlled rate of 55-60 blows per minute, and an electronic counter tracks each blow against the operator's preset target — typically 50 or 75 blows per face for standard Marshall mix design — before the unit stops automatically. The rigid main frame keeps the fall height and blow alignment constant throughout the run, removing the operator-to-operator variation that hand compaction introduces.

Applications
The Automatic Marshall Compactor is used in highway and airport pavement laboratories to prepare bituminous mix specimens for Marshall stability and flow testing under ASTM D6926, the standard practice for preparing Marshall specimens using mechanical compaction, and to support Marshall mix design procedures referenced in India's MoRTH specifications for road and bridge works. Typical users include highway construction contractors, asphalt plant quality control labs, and civil engineering institutions running bituminous mix design coursework.

Frequently Asked Questions
Q1. How is the Automatic Marshall Compactor different from a manual compactor?
It compacts specimens using a motor-driven hammer with an automatic stroke counter, removing the physical effort and stroke-count variability of hand compaction while keeping the same 4535 g hammer weight and 457 mm fall height specified for the Marshall method.
Q2. What blow counts can the machine apply?
The digital counter can be preset to stop after any target blow count, with 50 and 75 blows per specimen face being the counts most commonly used in Marshall mix design.
Q3. What specimen testing follows compaction?
Once compacted and cooled, specimens are typically tested on a Marshall stability and flow apparatus, such as the Marshall Stability Compression 50kN tester, to determine optimum bitumen content.
