The spec for highway works in the UK specifies a Gv of 3% for material with lime and/or hydraulic binder. Anyone know why it is set at 3%? I am doing some research on this test and find it hard to meet this criteria with the soils I am testing. They very rarely have a volumetric heave below 3% even though the CBR heave and strength is ok. Any thoughts??

Sounds like you need to sit down and discuss this with someone, are you UK based? See previous reply to BS EN 13286-49. ian_dot_gardner_at_xplor_dot_co_dot_uk
