Road Preservation FAQs
What is pavement preservation? According to the National Asphalt Pavement Association, the United States has more than 2.7 million miles of pavement, 94 percent of which use asphalt either as full-depth roadways or as overlays to restore aging concrete pavements. Roadway preservation typically consists of a programmatic approach to restoring a pavement’s original performance characteristics. […]
What is Asphalt Rejuvenation?
To rejuvenate asphalt pavement means to restore it to its original character. Lots of materials, from coal tars and emulsion sealers to today’s trendy biosolvents claim to rejuvenate. But genuine asphalt rejuvenation requires returning the precise maltene fractions that oxidation has removed from aging pavement. Rejuvenators using Maltene Replacement Technology (MRT) deeply penetrate aging asphalt […]
Sealing the Seam that Seals Your Roads
The premature failure of centerline joints, lane-to-lane joints and rumble strips is generally recognized by pavement preservation managers to be a grave threat to the sustainability of our federal interstate highway system). The longitudinal joints where paving mats meet in Hot Mix Asphalt (HMA) pavements and overlays are vulnerable to moisture intrusion should the wearing […]
Bio-Based Rejuvenators – A Review of Functionality
In recent years, there has been no shortage of confusion (and some intentional misdirection) in the asphalt pavement preservation marketplace in relation to the definition and understanding of maltenes and the role they play in rehabilitating and extending the life of asphalt roadways. For a clear understanding of the natural, resilient chemistry Pavement Technology calls […]
