XFEM simulation of reflective crack in asphalt pavement ...

Nov 20, 2018 · Fig. 6 presents the fracture life versus cracking propagation with different inclined degrees of initial crack in different models, which are with the initial cracking length 0 cm, 2 cm, 5 cm and 8 cm at the bottom of overlay. As shown in the figures, the crack propagates fastest in the models with inclined degree 0 °C, and the crack propagates slowest in the models with inclined degree 30 °C.

Review of fracture toughness (G, K, J, CTOD, CTOA) …

Fracture toughness is usually used as a generic term for measures of material resistance to extension of a crack. It is re-stricted to results of fracture mechanics tests in this work, which are directly applicable to fracture control and to fracture test in describing the material property for a crack to resist fracture.

Using fracture slab technology to minimize reflection cracking

Using fracture slab technology to minimize reflection cracking ... slabs must be cracked through the entire layer depth to be effective in controlling cracks from reflecting through the overlay. Cracking/seating is an effective technique for addressing unstable slabs and working cracks or joints within the pavement. ... This process typically ...

TLN - Cracking and Debonding of a Thin Fiber Reinforced ...

Also, bond tests indicated that interfacial fracture occurred through the overlay mixture and was proportional to the number of fibers which intersected the fracture path near this interface. The finite element analysis verified that crack width, vertical lift off, and debonding length all decrease as the fracture energy across joint increases or as the interfacial tensile bond increases.
