Coeff. of static friction between concrete and asphalt
Coeff. of static friction between concrete and asphalt
(OP)
Anyone have a reference for static friction coefficient for mass concrete on asphalt pavement?
I am trying to evaluate the effectiveness of using a standard traffic barrier section as a retaining structure for a modest (2-foot high) fill. The traffic barrier is normally cast-in-place on top of the intermediate asphalt course using a slipform.

My situation involves bituminous pavements - no dowelling.

I think I'll just specify some embedment into the bituminous pavement section and choose a conservative Kp, or recommend dowelling into a concrete pavement.

I asked around and I have been shown some test data on portable concrete barrier on asphalt pavement. The results indicate a static friciton coefficient of about 0.55 to 0.6. I would use a value of about 0.5 to be a little conservative.

I was driving the Pennsylvania Turnpike this weekend, and it looks like they use barrier as a retaining wall along the western part south of Pittsburgh.

The PA Turnpike is also doing the same in the Philadelphia area right now.
