Hot job summer: The asphalt pavement process

 


By Tim Potter, 
District Five Public Affairs Manager 

Imagine this: You’re under a blinding sun along U.S. 50 near the town of Walton, and the combined heat and humidity makes it feel like around 106 degrees. It’s suffocatingly hot, the kind of conditions that trigger a heat advisory.

Not just that: You’re laying down asphalt cooking at around 250 degrees when you first apply it. The stiff south wind feels like more of a blast furnace than a cooling breeze. You’ve worked through lunch because overlaying a side road at a highway is one of those jobs where it’s not real practical to take a normal 30-minute break. The equipment has been strategically positioned, and the different tasks involved must click right along. The asphalt -- and the process for applying, shaping and finishing it -- is demanding, unforgiving.

That is what it was like for a combined team of crew members – from the Newton Subarea, District Special Crew and El Dorado Area and El Dorado Subarea -- the afternoon of July 28. If you had to visit one of the hottest KDOT jobs on an extra sweltering day, this was it. They had been overlaying side roads for almost two weeks.

Sweat beads covered the reddened face of Bobby Jones that afternoon as he matter-of-factly explained the work being done and the reality of enduring merciless weather.

“The hotter it is, the nicer it lays,” Jones said of the asphalt. “You have to work it while the asphalt’s hot.” The Newton Subarea Supervisor watched a massive roller compact the new surface. Even though they had paving machines, some of the finishing and clean-up tasks must be done by hand, by bending over a shovel and pushing and lifting.

Through it all, “You have to drink lots of fluids; otherwise, you’ll be laid out on top of the asphalt,” Jones said. “If you don’t keep hydrating, this heat will take it right out of you in a heartbeat.”

Everyone had a different role in the overlay job, and part of it was paying attention to their co-workers – operators making sure they didn’t drive over someone, everyone staying aware of the semis barreling past only feet away, everyone making sure that the next person wasn’t overcome by the heat.

“This is a team effort,” Jones said. “We all have to watch out for each other.”
