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.

Made to order, allow 8-12 weeks for delivery.
