Clegg Soil Impact Tester 20kg

The 20 kg "Heavy" Hammer was developed for testings on the running course of flexible pavements. Its hammer diameter is 13 cm meaning that it is also tests through a larger zone than other Hammers. Its larger mass and diameter means a reduction in output sensitivity enabling testing of materials harder than 100 CIV (of the Standard Hammer).

Because of its weight, the Heavy Hammer has a guide tube with wheels and a pull-handle to ease moving around the site. In the GTM style, the weight of the guide tube is around 17 kg and the shipping case weighs around 18 kg for a combined total shipping weight with the 20kg hammer of 55kg. Case dimensions are 38 cm by 49 cm by 86 cm. Standard drop-height for the Heavy Hammer is 30 cm. Notation for the output is CIV/H when the 20 kg Hammer is dropped from its standard height of 30 cm.
