The Texas Department of Transportation (TxDOT) is trying to accomplish approval victory on a grand scale with the construction of the Dallas High Five interchange—which will sit in an area that attracts a bewildering 500,000 vehicles daily. Two major highways, U.S. 75 (North Central Expressway) and I-635 (LBJ Freeway), are the two main carriers, and effective traffic management during the creation of Dallas’ first five-level road structure has been the top promise since day one.

Philosophical Asphalt

The Greek philosopher, Aristotle, was never a part of a hot-mix asphalt (HMA) paving crew and never worked at a hot-mix plant, but his teachings are applicable to the field, at least in the case of Shalimar, Fla.-based Couch Construction LP. The philosopher’s thoughts on excellence in association with other ideas on courage, humility and nobility served as guiding principles by which the employees of the company have lived in recent years.

All other things being equal in the asphalt compaction process, an increase in the ground speed of a vibratory roller can translate directly into an increase in profit or decrease in expense, depending on which side of the equation you are on. But there’s one catch–anyone understanding the theory of vibratory compaction knows that the above statement can only be true with a corresponding increase in vibration frequency.
