Asphalt Specific Gravity

Asphalt Specific Gravity

Asphalt Specific Gravity

(OP)
I have not been able to find a good source for typical specific gravities for emulsified asphalt.  There are plenty of sources for asphalt mixtures but not just the emulsion.  Does any have a good source or know what the typical value is?

RE: Asphalt Specific Gravity

Have you contacted any suppliers?  They should be able to point you in the right direction.  Also check with your state's highway department -

RE: Asphalt Specific Gravity

We've tested it before for blasting purposes.  It was about 2.1gm/cc.  I'm sure it varies depending on raw materials (aggregate) used.  Contact the National Asphalt association for some info.

Focht3,

I have checked with the supplier on the project we are working on and they say that the emulsified asphalt that they add to the RAP (Recycled Ashpalt Pavement) has a specific gravity of 1.006, Indicating that it is heavier than water.  I always thought that the liquid form was lighter than water, but I could wrong.

RE: Asphalt Specific Gravity

No, I'd expect it to be a little heavier - so your information seems correct.  (I wouldn't have been surprised if you had said the value was 1.1 to 1.2.)  But I'm not an asphalt jock -
