Layers of repaving “fills” curbing and leads to flooding. Right shows how it's supposed to look

Layers of repaving “fills” curbing and leads to flooding. Right shows how it’s supposed to look

At the last Preston Center Task Force Meeting, TXDoT spoke about their progress repaving of Preston Road and my ears were pricked.  Preston Road was originally constructed with concrete and is now (again) being over-paved in Asphalt.  It’s been going on for years, but why? Other roads like Greenville are being repaired in concrete.

The federal government reports that concrete roadways last an average of 2.5 times longer than asphalt.  Another report states that concrete lasts 27.5 years before major repair while asphalt only lasts 15.5 years.  Non-highway roadways can have a life expectancy of over 60 years (how old is Preston Road’s concrete?).  Long-term, concrete roadways can save 19 percent in maintenance costs over asphalt.
