Felt paper is available in several grades, the most common being Type 1—commonly called 15-pound (15#) or No. 15 (#15)—and Type 2—commonly called 30-pound (30#) or No. 30 (#30). The weight designations originated with organic base felt weighing 15 or 30 pounds per 100 sq. ft. (6.8 kg or 14 kg per 9.3 m 2 ).
Its bank density (the density of a coal seam prior to breaking up during mining) is about 1346 kg/m 3 (84 lb/ft 3) while the bulk density of extracted coal is up to 833 kg/m 3 (52 lb/ft 3). [12] Bituminous coal characteristically burns with a smoky flame and softens and swells during combustion. [13]
An average example in the United States is about 112 pounds per square yard, per inch of pavement thickness. [21] When maintenance is performed on asphalt pavements, such as milling to remove a worn or damaged surface, the removed material can be returned to a facility for processing into new pavement mixtures.

Several variations of bitumen roofing felt are available. Single coverage thicknesses range from 55 to 90 pounds per square (100 sq. ft.) for single-coverage; Double coverage range from 110 to 140 pounds per square. [4] Fibre content: mixed rag fibre - lowest cost, shortest life; all plastic fibres; fibreglass - longest lived; Bitumen:
The exact number of cans per pound can't be quantified due to different measurements. Depending on the brand, estimates show there are usually 32 to 35 cans per pound. For smaller, more common 12 ...
Ignoring such constraints, and also assuming that the price of oil recovers from its collapse in late 2014, the list of currently proposed projects, many of which are in the early planning stages, would suggest that by 2035 Canadian bitumen production could potentially reach as much as 1.3 million m 3 /d (8.3 million barrels per day) if most ...
By March 30, 2020, the price of WCS bitumen-blend crude was US$3.82 per barrel. [55] In April 2020 the price briefly fell below zero, along with WTI, due to collapsing demand caused by the COVID-19 pandemic. [56] [57] In June, the Western Canadian Select (WCS) benchmark price averaged $64.35 per barrel, which was closely aligned with the year ...
