If the material does not meet all applicable Crack Sealing Machine specifications, it should be rejected. On the other hand, good performance does not guarantee material compliance with specifications. Proper installation is a must, no matter how good the material.
Sealant and filler materials can be placed in cracks in numerous configurations by Crack Sealing Machine Pouring; the most common are shown. These placement configurations are grouped into four categories.
Flush fill 2. Reservoir 3. Overband 4. Combination (Reservoir and Overband).In the flush fill configuration, material is simply dispensed into the existing, uncut crack and excess material is struck off.
In an overband configuration, the material is placed into and over an uncut crack.
If the material over the crack is shaped into a band using a squeegee, then the simple band-aid configuration is formed. If the material over the crack is left unshaped, then the capped configuration is created. All these situation will effect the Crack Sealing Machine final construction result.
