The Marshall Stability Machine is used to determine the load and flow values of bituminous mixtures.The Marshall is composed of a robust and compact two-column frame with an adjustable upper cross beam driven by an electro-mechanical ram with a maximum capacity of 50 KN and a data acquisition and processing system.The Marshall Stability Machine can be hand operated by a lateral hand wheel for calibration purposes. The mechanical jack raises the lower cross beam at a constant speed of 50.8 mm/min.The limit switches are provided for both, bottom and top limit of travel.The Automatic measuring system consists of a 50KN capacity strain gauge load cell that is fitted to the upper cross beam to read stability values and 25 mm x 0.001 mm displacement transducer fitted to Break Head.The Manual measuring system consists of a 50 KN capacity load ring and dial gauge graduated 0.01 mm with 25 mm travel.Product Features:-Marshall Apparatus is used to carry out the stability test.The test is intended for the measurement of the resistance to plastic flow of cylindrical specimens of bituminous paving mixture loaded on lateral surface For use with hot mixture containing asphalt or tar and aggregate up to 25.4mm maximum size.Technical Details:-Drop distance - (457±1.5)mm Compaction speed - 60±5 times/minute Compaction preset number - 0－999 times Hammer weight - 10210g±10g/ 4536±9g Test mode cylinder diameter - 152.4mm/101.6mm Dimensions - 670X570X1800mm Weight - 175kg Ambient temperature - 5～40℃ Environment humidity - ≦85﹪
