Method to determine full work of fracture from disk shaped ...

Fatigue cracking is an important mode of failure in hot-mix asphalt (HMA). As part of the revision of the South African pavement design method (SAPDM) a need was identified to assess the fracture toughness of HMA in terms of fracture energy. The disk shaped compact tension test (DSCTT) was selected to experimentally determine the fracture energy.
