Historically, most Crack Sealing has been performed on a routine basis with inappropriate materials that provide less than desirable performance. This approach to Crack Sealing is rarely cost-effective because treatment performance is generally poor and maintenance costs are high. In addition, the safety of the workers and traveling public is compromised, since the filling operation must be repeated frequently.
The following factors should be addressed when planning Crack Sealing or crack filling operations:
Climatic conditions.
At time of installation.
In general
Highway classification.
Traffic level and percent trucks.
Crack characteristics and density.
Materials.
Material placement configurations.
Procedures and equipment.
Safety
The planning process centers on selecting an appropriate material and placement configuration, and determining the procedures and equipment to be used on existing and future roadway conditions.
