The reason of the crack and its action play a dominant role in determining the success of crack sealing or filling operations.
This chapter addresses crack sealing and filling techniques associated with flexible hot mix asphalt (HMA) pavements and joint and crack sealing of firm portland cement concrete (PCC) pavement systems.
The reader is advised to pay close attention to the kind of pavement system being addressed, as treatment techniques can be different.
Cracking may be connected with diverse distress mechanisms. Crack types comprise: fatigue cracks, longitudinal cracks, transverse cracks, block cracks, reflective cracks, edge cracks, slippage cracks and joints in PCC pavements.
CRACK SEALING
Cracking
in pavements occurs while a stress is built up in a surface layer that exceeds
the tensile or shear strength of the pavement causing a fissure or crack to
open.
Crack
sealing and crack filling are methods which can be used to revamp these cracks
in pavement surfaces.
