“Rejuvenators will retard the loss of surface fines and reduce the formation of additional cracks.” – WSDOT
Bringing Aging Pavement Back to Life
The oxidative aging of pavements begins during the construction process and continues throughout a pavement’s life. The most severe aging occurs within the first two to four years of service life. Ultraviolet light from the sun, water and the environment causes surface age hardening with the top of the pavement becoming more brittle than the underlying material. While the hardening of the asphalt and the micro-cracks may not be visible, the damage is beginning and can result in raveling and/or premature cracking originating at the pavement surface.
Pavement rejuvenators are sprayed on existing aged or oxidized HMA pavements in order to restore pavement surface flexibility and to retard cracking and raveling. Emulsified sealers, binders and rejuvenators are used to protect oxidized asphalt surfaces and rejuvenate them. Rejuvenators are formulated with oils to penetrate into the pavement and then enhance the properties of the asphalt binder of the existing pavement. The chemistry of the rejuvenators is designed to replenish the oily fraction of the asphalt.
