  200 shells per â¦ carton. 600 cigarettes per pound so 16 ounces divided into that is .03 ounces per cigarette or 6 ounces per carton. so 0.6 ounces per pack so the shell weighing .4 to .5 ounces makes sense I guess. Metric scale to .001 ounce needed.
Bitumen is also frequently called tar or pitchâthough, properly speaking, tar is a byproduct of the carbonization of coal and pitch is actually obtained from the distillation of coal tar. Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10Â° and a viscosity greater than 10,000 centipoise.
On the other hand, bitumen with low penetration grade or hard bitumen has less low temperature cracking but more rutting resistance [ 1, 2 ]. This alteration can be related to the complex rheological behavior of bitumen at different loading times and temperatures [ 3, 4 ].n the other hand, bitumen with low penetration grade or hard bitumen has less low temperature cracking but more rutting resistance [ 1, 2 ].
