BACKGROUND:
Background
Conventional micro surfacing and slurry seal systems have played an important role in pavement preservation for the city of Dallas for decades. However, in the time it takes these systems to fully cure, especially during periods of extreme heat and high humidity which happen quite often in Texas, the treated roads can sometimes be susceptible to power steering burns, raveling and other vehicular damage. While the long-term benefits have historically outweighed these short-term inconveniences, Dallas was interested in systems that can provide a more durable wearing course sooner after application, while still providing long-lasting benefits.
Highly Polymer Modified = Increased Durability, Longevity, Friction
In 2016, Ergon Asphalt & Emulsions’ Area Sales Manager David Stroud and Technical Marketing Manager Tom Flowers introduced Dallas road officials to the eFlex solutions for their short- and long-term pavement preservation needs. eFlex premium micro surfacing and eFlex ES premium slurry seal systems are both highly polymer modified for increased durability and longevity. In addition to providing increased protection from scuffing and power steering burns early on, eFlex and eFlex ES also provide high friction surfaces that retain their friction levels even in harsh conditions throughout the life of the treatments, increasing the safety of the driving public.
After demos were conducted, the city was pleased with the finished product. eFlex and eFlex ES had withstood intense traffic and extreme temperatures. The decision was made to include highly polymerized premium micro surfacing and highly polymerized premium slurry seals in the city’s 2017-2018 pavement management program.
