Tarmac

(OP)
I have been searching for the unit weight of tarmac on the interent for a bridge design, but couldn't find any references. DOes anyone have any information on the topic

RE: Tarmac

"Tarmac" is not a material, but a company based in the UK that produces asphalt (and many other products). Here is a link http://www.tarmac.co.uk/index.htm
The word "Tarmac" is often used to mean (generic) asphalt.

However is you need the properties of a specific Tarmac product, best to contact a company representative.

RE: Tarmac

I am pleased to hear an intelligent definition.

"Tarmac" is flippantly used to denote any area of an airport, which is not a runway. (US)

Buy a dictionary, keep it nearby and USE it. Webster's New World Dictionary of American English is recommended, and Webster's Collegiate Dictionary.

RE: Tarmac

Just finished a bridge with 75mm thick asphaltic concrete surfacing. The density measured in the lab averages 2.12T/m3.  For superimposed deadloads the code you're working to may require addition of a factor (20-25%). This may also be the case for all SDL - kerbs, median etc.

As SlideRuleEra suggests a supplier of bitumenous materials will give you densitys of all the products which he supplies.  

RE: Tarmac

[For any interested I believe Mr. Zambo's recent "average lab density" equates to about 132 lb/ft3, if I understood his metric units correctly].   

RE: Tarmac

and a tarmac road is also called a macadam road in some areas.
