TAMPERS

S3141 These tampers are used along with the proctor molds to prepare moisture density samples for the proctor test. There are three types of tampers, 5-1/2 lb with a 12" drop, 10 lb with an 18" drop, and 5-1/2 lb with an 18" drop. The tamper weights have a 2" diameter face. The guide tubes have vents to prevent any air pressure from developing and all parts are plated to prevent rusting. The S3143 tamper is not required by ASTM or AASHTO. The U.S. Army Corps of Engineers Tamper is guided on a shaft instead of a sleeve. The length of the drop is slightly adjustable. The foot assembly has a recoil mechanism which reduces the impact and the fatigue on parts.
