  2. Pitch (resin) - Wikipedia

    en.wikipedia.org/wiki/Pitch_(resin)

    Natural bitumen pitch, from the tar pit above the McKittrick Oil Field, Kern County, California. Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, [1] or plants. Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid ...

    en.wikipedia.org/wiki/List_of_commercially...

    Modified bitumen are long rolls of asphalt-based materials, that can be heat-welded, self-adhering asphalt-adhered, or installed with adhesive. Asphalt is mixed with polymers such as APP or SBS, then applied to fiberglass and/or polyester mat, seams sealed by locally melting the asphalt with heat, hot mopping of asphalt, or adhesive.

  4. Bituminous waterproofing - Wikipedia

    en.wikipedia.org/wiki/Bituminous_waterproofing

    Bitumen (asphalt or coal-tar pitch) is a material made up of organic liquids that are highly sticky, viscous, and waterproof. [1] Systems incorporating bituminous-based substrates are sometimes used to construct roofs, in the form of "roofing felt" or "roll roofing" products.

  5. Bitumen - Wikipedia

    en.wikipedia.org/wiki/Bitumen

    Mastic asphalt is a type of asphalt that differs from dense graded asphalt (asphalt concrete) in that it has a higher bitumen content, usually around 7–10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% asphalt. This thermoplastic substance is widely used in the building industry for waterproofing ...

  6. Bituminous geomembrane - Wikipedia

    en.wikipedia.org/wiki/Bituminous_geomembrane

    This novel bituminous geomembrane was made by spraying hot bitumen in-situ onto a polyester geotextile. [6] Soon after these early installations, factory manufactured BGMs were developed with factory impregnation of bitumen into the geotextile allowing a high standard of quality control. Spray applied BGMs went entirely out of favor by 1988. [7]

  7. Asphaltite - Wikipedia

    en.wikipedia.org/wiki/Asphaltite

    Asphaltite (also known as uintahite, asphaltum, gilsonite or oil sands [1]) is a naturally occurring soluble solid hydrocarbon, a form of asphalt [2] (or bitumen) with a relatively high melting temperature. Its large-scale production occurs in the Uintah Basin of Utah and Colorado, United States.

  8. Tar paper - Wikipedia

    en.wikipedia.org/wiki/Tar_paper

    Tar paper is used as a roofing underlayment with asphalt, wood, shake, and other roof shingles as a form of intermediate bituminous waterproofing.It is sold in rolls of various widths, lengths, and thicknesses – 3-foot-wide (0.91 m) rolls, 50 or 100 feet (15 or 30 m) long and "15 lb" (7 kg) and "30 lb" (14 kg) weights are common in the U.S. – often marked with chalk lines at certain ...

  9. Asphaltene - Wikipedia

    en.wikipedia.org/wiki/Asphaltene

    Asphaltenes are molecular substances that are found in crude oil, along with resins, aromatic hydrocarbons, and saturates (i.e. saturated hydrocarbons such as alkanes). [1] [2] The word "asphaltene" was coined by Jean-Baptiste Boussingault in 1837 when he noticed that the distillation residue of some bitumens had asphalt-like properties.
