  2. 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.

  3. Bituminous geomembrane - Wikipedia

    en.wikipedia.org/wiki/Bituminous_geomembrane

    Bituminous geomembrane (BGM) is a type of geomembrane consisting of a reinforcing geotextile to provide mechanical strength and elastomeric bitumen (often called asphalt in U.S.) to provide impermeability. Other components such as sand, a glass fleece, and/or a polyester film can be incorporated into the layers of a BGM. [1]

    en.wikipedia.org/wiki/Asphalt_concrete

    Asphalt batch mix plant A machine laying asphalt concrete, fed from a dump truck. Asphalt concrete (commonly called asphalt, [1] blacktop, or pavement in North America, and tarmac or bitumen macadam in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams.

  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. Geomembrane - Wikipedia

    en.wikipedia.org/wiki/Geomembrane

    While each is material-specific, the general behavior trend is to cause the geomembrane to become brittle in its stress-strain behavior over time. There are several mechanical properties to track in monitoring such long term degradation: the decrease in elongation at failure, the increase in modulus of elasticity , the increase (then decrease ...

  7. Waterproofing - Wikipedia

    en.wikipedia.org/wiki/Waterproofing

    In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents and structural integrity. The waterproofing of the building envelope in construction specifications is listed under 07 - Thermal and Moisture Protection within MasterFormat 2004, by the Construction Specifications Institute, and includes roofing and waterproofing materials.

  8. Membrane roofing - Wikipedia

    en.wikipedia.org/wiki/Membrane_roofing

    Modified Bitumen – Polymer Modified Bitumen Membranes were developed in Europe in the mid-1960's and have been in common use throughout the United States since 1975. they are composed of one or more premanufactured sheets consisting of asphalt, reinforcing layers, and in some cases a surfacing is applied. During manufacture, plastics or ...

  9. Chipseal - Wikipedia

    en.wikipedia.org/wiki/Chipseal

    The introduction of polymer-modified bitumen and emulsion binder has increased chipseal's ability to prevent crack reflection and improve stone retention by improving the properties of the bitumen binder. Newer techniques use asphalt emulsion (a mixture of liquid asphalt, surfactant, and water) instead of asphalt. This has been shown to help ...
