Faces of Evotherm: Bob Siffert


Bob Siffert is the kind of guy you can have lunch with and cover everything from Richard Simmons, natural talents and a great throwback story from a jobsite. Sound like fun? That’s an understatement when describing this technical marketing manager based in Boise, Idaho. Fast forward through the part where he tells you that he takes pride in helping contractors understand the value of WMA and enjoys being a part of crews’ transitions from HMA to WMA, and you get to all the best parts.

What’s your idea of happiness?

Paving boots and long, cool walks on 240 degree WMA.

Your idea of misery?

Being burned alive by 340 degree HMA.

If not yourself, who would you be?

Richard Simmons.

Name your hero in life.

Richard Simmons, of course.

Where would you like to live?

The wilderness.

What natural talent would you like to have?

A photographic memory.

Tell us about your favorite memory on a project.

All seemed to be lost when we had a long haul mountain project that was held up for seven hours due to rain. We were certain that the line of 17 trucks would be sent home with cold asphalt when, to our surprise, we discovered the mix was a chilly 170 to 190 degrees behind the screed. We rolled it once and nothing happened. We rolled it twice and nothing happened. We rolled it a third time and by some miraculous, Evothermic development, the mix came back to life. The words "Hit it again!" rang out several more times and by the time they dropped the gauge on the mat, passing density numbers had been born. It was epic.

When he is not imagining life as Richard Simmons or telling epic tales, Bob can be found enjoying life while hunting, fishing, hiking, and mountain biking.
