Transverse cracking -- we do projects with lots of transvers cracking and like mill and fill projects they come back over time.
Bleeding -- bleeding pavements are considered
Existing pavement thickness -- minimum 50 mm to 100 mm. Although we have done roads with an asphalt depth of only 50mm and recycled the top 40mm, the projects were still considered to be very successful.
Roughness -- smooth to moderate. We have done rough roads and it was made way better
Structural condition -- minimum structural capacity based on strength testing
Projects with extensive rubberized crack sealant or high percentages of rubber tires may not be considered. However we do major crack sealing very often.
Bottom lifts then overlaid for structural strength with hot mix
Chip sealed or seal coated is okay
Four inch rehabilation - two inch hot-in-place plus two inch overlay
