Certain asphalt maintenance and preservation methods extend the life of asphalt and reduce the frequency in which surfaces need to be extensively repaired or replaced.
There are three types of pavement maintenance operations:
-Preventative Maintenance: Anything that improves overall functionally and extends the life of pavement. This includes a variety of surface treatments that ultimately decrease the need for constant maintenance and service activities.
-Corrective Maintenance: This includes any measures taken after an issue or defect arises including loss of friction, rutting or cracks.
-Emergency Maintenance: This entails any repairs that must be conducted immediately such as filling a severe pothole. This also includes temporary treatment measures used to resolve an issue before more permanent repairs are conducted.
