Do We Really Have to Choose Between Reducing Pollution and Destroying Human Prosperity?
Scientists have noted that worldwide quarantines have dramatically reduced ground-level air pollution. In Paris, nitrogen dioxide readings have dropped a stunning 60 percent in the past few weeks. But what we’ve also learned in this pandemic is that austerity and abstinence, the long-offered solution to urban smog, will have a devastating impact on the human […]
What Method of Pavement Preservation Works Best?
We see and use them every day, and yet we totally underestimate their value. Most people never give them a second thought. But let them get rough or cause damage to our vehicles, and suddenly we take notice. I am of course describing our pavements…the path that runs through our communities, the ribbon that ties […]
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 […]
Longitudinal Joints: Sealing Road Seams for Pavement Preservation
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 […]
ASPHALT ROAD BIO-BASED REJUVENATORS – FUNCTIONALITY REVIEW
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 […]
