They use asphalt as the base when making running tracks not concrete.
Also, quoting an unnamed source while you are an unnamed source makes you seem like an idiot.
Not always! For example, Husky Track at Univ. of Wash., constructed in summer 2012, has a cement concrete base, with lots of rebar, and it is not the only such example. I will agree that most are asphaltic concrete, which is cheaper, not better.
Also, posting something incorrect as a fact makes you seem like an idiot.

Also, in engineering terms asphalt is considered a type of concrete - bituminous concrete, to be exact. The pic someone posted on the first page shows them setting pilings, so the soil was probably too soft to support a track . The pilings would need to be capped with rigid reinforced concrete, and then it's possible they would have poured asphalt over that to give the track a softer base.

You did notice that I used the term "asphaltic concrete." At UW, they drove in over 150 deep pilings, and the Beynon BSS2000 surface was poured directly onto the cement concrete oval base; no asphalt used.

I didn't know it was in a flood plain.

This happened at UCLA several years back. They redid the track then a year later needed to patch up holes in the turns. Then they needed to redo the whole thing again a couple years later.

Jesus, learn how to use the message boards. You buried your own response inside of my quote. And I was agreeing with you, not arguing with you.

re: Dean Dome

Is there a news article for this so we can see what happened?

Any update on the facility situation?

Just stopped by at the track this afternoon. Sign still said "track closed for repairs." No sign, though, of any work in progress.

100% of German Scientists agreed Albert Einstein's theories were wrong.

With the insights we have now, the vast majority of the contemporaneous criticism of his theory of relativity was motivated by political or religious reasons. What does that remind you of?

Science has nothing whatever to do with agreement, except agreement with experimentation.

Of course the only agreement in science worth mentioning is agreement with experimentation. Climate change is supported by a massive number of experimental and observational studies. The null hypothesis is not.

The failed track in NC has nothing at all to do with sea level rise or the rise in temperatures since the beginning of the industrial revolution. Failed engineers and scientists had everything to do with the failure.

Totally agree
