Below is a good example of a highly oxidized pavement that was recently crack sealed and then had an asphalt surface treatment placed. It is easy for a manufacturer to call an application like this a "rejuvenator," but it is simply a protective coating for the asphalt.
preventive maintenance treatment, and should be scheduled for rehabilitation or reconstruction. Maintenance treatments covered in this handbook include: Crack repair wisealing, including clean and seal, saw and seal, and rout and seal; crack
Compared with crack self–healing via infrared heating or microwave heating, the automatic induction self–healing treatment (AI–SHT), which has the advantages of construction automation and high efficiency, is widely regarded as the most cost-efficient pre-maintenance method to repair cracks in asphalt concrete [,,, ].Electromagnetic induction heating for healing purposes was first ...
For existing HMA pavements, one of the following treatment methods may be selected: o. Crack sealing and overlay (pros: low cost and suitable for cracked asphalt pavements; cons: reflection cracking may still appear). o. Chip seal interlayer (pros: low cost and adequate control of reflection cracking). o

In general, cracks that display significant raveling of the crack face and secondary branch cracking (Figure 551-1) need more than just a crack seal and should be considered for some other treatment. Furthermore, pavements that require more than 5000 pounds of crack seal material per lane mile (1400 kg per lane km) are questionable candidates ...
Many types of crack treatment materials are available. The principal material families and types are given in Table 1. Asphalt cement and liquid asphalt possess little flexibility and are very temperature susceptible, so they are limited to use as fillers in non-working cracks.

With crack filling treatment a new asphalt mat will be again placed after 5 years and with crack sealing after 7 years. This is the reason behind the consideration of a 35 year analysis period to analyze the long term cost effectiveness between these two treatments. In between 35 years, resealing with crack filling treatment will be performed 7 ...
The cause of the crack and its activity plan an important role in determining the success of crack sealing or filling operation. Cracks in asphalt pavement are inevitable, and crack filling and sealing should be considered the first line of defense in asphalt pavement maintenance, whether it's considered routine or preventive maintenance.
The sealing process is a localized treatment that is used to prevent water and debris from entering cracks in asphalt and concrete pavements. The crack sealants can be asphalt emulsions, asphalt cement and different types of rubberized asphalt. Crack sealing/filling can be a very effective pavement maintenance tool.
