Ручной уплотнитель Marshall в сборе

Manual Marshall Hand Compaction Assembly is designed to compact asphalt mixtures under standard impact energy in the laboratory and to prepare specimens for Marshall stability testing. The system consists of a hammer, guide, and mold. The hammer is released from a specified height to compact the mixture in successive blows, producing homogeneous and repeatable specimen density. This method is a standard laboratory procedure for preparing specimens used in Marshall stability and flow tests. The hammer and mold components manufactured by YKMTEST are made of high-strength steel for long service life. Compaction is performed under guidance to keep the hammer axis perpendicular to the mold. Blows are evenly distributed over the mixture surface, resulting in uniform density across the specimen, enabling behavior similar to field compaction. Each specimen is compacted with a specified number of blows. This manual system is an ideal solution for laboratories where automatic compactors are not available, for university teaching labs, or for applications requiring a limited number of specimens. YKMTEST Marshall Hand Compaction Assembly provides a durable steel structure, precise drop mechanism, and fully standard-compliant dimensions, offering an economical, practical, and repeatable specimen preparation system for asphalt mixture laboratories.
