Asphalt Specific Gravity

[GTB]

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?

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

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.

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 -
