Forensic Investigation of Pavement Failure on Vasquez Boulevard
Vasquez Boulevard between mileposts 291 and 297 in Commerce City was originally constructed in the 1940s with asphalt that didnt contain an anti-stripping agent. It is now part of US Highway 6 and has been designated as an over-weight and over-height relief route for the I-25 corridor. The boulevard has become a main trucking route for a heavily industrialized area. There was a major rehabilitation project in 2001 on this stretch of road with 2 milling and 2 stone matrix asphalt (SMA) paving. Parts of this pavement started rutting less than a year after construction. An investigation of the pavement failure determined that the causes were excessive and repeated loading of over-weight and over-height trucks; exposure of milled surface that didnt contain an anti-stripping agent to traffic and weather; inexperience with SMA paving materials, testing, and construction; and highly variable mix gradation and AC content quality levels. Recommendations for future SMA projects include training personnel to understand the complexities of SMA; establishing rigorous methods of calculating ESALs; adding fibers to reduce draindown and increase film thickness; using material transfer vehicles to minimize segregation and improve smoothness; and specifying the Superpave Gyratory Compactor for design and verification testing.
