Actual field performance should always be considered when determining which material to use for Crack Sealing Machine. Maintenance planners should not only keep abreast of the results of national and state crack treatment studies, they should also stay informed of local experiences with material performance. Results from the recently concluded some city road crack treatment study indicate the following material performance capabilities, given proper installation:
Crack Sealing Machine use the emulsion and asphalt cement filler materials placed flush in unrouted, non-working cracks can perform satisfactorily for between 2 and 4 years, whereas rubber and fiber modified asphalt fillers placed flush or overbanded in the same cracks can serve effectively for 6 to 8 years.
Rubberized asphalt sealants also can be used by Crack Sealing Machine placed flush or overbanded in routed, working cracks can provide between 5 and 9 years of service, whereas placed overbanded in non-routed working cracks, they can provide 2.5 to 5 years of service.
Self-leveling silicone placed recessed in routed/sawn working cracks can perform satisfactorily for at least 4 to 6 years.
Fiberized asphalt placed overbanded in unrouted, working cracks can provide a maximum of 2 year of adequate service.
