Preventative Maintenance and CAP Reduction Sealing Technology of Asphalt Pavement

The decaying characters of application performances on asphalt pavement under loading and environmental factors were analyzed.Preventative maintenance technology was adopted maintain good state of pavement while prevent or control occurrence and development of disease.The traffic safety could be guaranteed and maintenance cost decreased.The adoption of CAP regenerated reduction sealing reagent could improve the properties of asphalt mixture greatly,such as increment of bonding force,sealing of microcracking,forbidden of the aggregates loosening.
