The Vermont Agency of Transportation (VTrans), with headquarters in Montpelier, has typically employed common preventive maintenance treatments such as bituminous crack fill sealant, micro surfacing, various seals, ultra thin lays, hot-in-place bituminous overlays, and more. These treatments have proven to be effective. Their costs, however, can be fairly expensive, depending on the treatment and roadway […]

Brooklyn Bridge relies on micro surfacing for a smooth ride for its more than 100,000 average daily vehicles. Asphalt Paving Systems is there to help.

Maine DOT uses GSSI’s PaveScan RDM to measure whether there is uniform density throughout a pavement layer.

Sandy Lender uncovers the best practices of how to place an ultra thin lift pavement treatment.

In the January 2018 issue, Courtney Jones and Mike Heitzman from the National Center for Asphalt Technology (NCAT) at Auburn, shared “Michigan Tests Friction Aggregates” from their contribution to the fall 2017 NCAT Newsletter. This excellent article can be reviewed on www.TheAsphaltPro.com. The authors shared results of evaluating 11 aggregates for high friction surface treatments […]

Editor’s Note: Read the February issue for findings from the Florida Department of Transportation’s experience with HFSTs over time. High friction surface treatments (HFST) provide enhanced pavement friction in critical safety locations such as horizontal curves and bridge decks. HFSTs are a thin layer of durable, high friction aggregate bonded to an existing pavement surface […]

When it comes to minor surface distress, sometimes the best option is to perform an overlay. “Overlays have some distinct advantages compared to less costly surface maintenance treatments,” said Terry Humphrey, a training consultant at Caterpillar Paving Products, Peoria, Illinois. “In addition to sealing shallow fatigue cracks, overlays add strength to the existing structure and […]
