Tarmacadam
Tarmacadam is a road surfacing material made by combining crushed stone, tar, and sand, patented by Welsh inventor Edgar Purnell Hooley in 1902. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces invented by Scottish engineer John Loudon McAdam in the early 1800s. The terms "tarmacadam" and tarmac are also used for a variety of other materials, including tar- grouted macadam, bituminous surface treatments and modern asphalt concrete. Origins Macadam roads pioneered by British engineer John Loudon McAdam in the 1820s are prone to rutting and generating dust. Methods to stabilise macadam surfaces with tar date back to at least 1834 when John Henry Cassell, operating from ''Cassell's Patent Lava Stone Works'' in Millwall, England, patented "lava stone". This method involved spreading tar on the subgrade, placing a typical macadam layer, and finally sealing the macadam with a mixture of tar and sand. Tar-grouted macadam was in use well before ...

Asphalt Concrete
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt 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. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process was refined and enhanced by Belgian-American inventor Edward De Smedt. The terms ''asphalt'' (or ''asphaltic'') ''concrete'', ''bituminous asphalt concrete'', and ''bituminous mixture'' are typically used only in engineering and construction documents, which define concrete as any composite material composed of mineral aggregate adhered with a binder. The abbreviation, ''AC'', is sometimes used for ''asphalt concrete'' but can also denote ''asphalt content'' or ''asphalt cement'', ...

Airport Apron
The airport apron, apron, flight line, ramp, or tarmac is the area of an airport where aircraft are parked, unloaded or loaded, refueled, boarded, or maintained. Although the use of the apron is covered by regulations, such as lighting on vehicles, it is typically more accessible to users than the runway or taxiway. However, the apron is not usually open to the general public, and a permit may be required to gain access. An apron's designated areas for aircraft parking are called ''aircraft stands''. By extension, the term ''apron'' is also used to identify the air traffic control position responsible for coordinating movement on this surface at busier airports. When the aerodrome control tower does not have control over the apron, the use of the apron may be controlled by an ''apron management service'' (''apron control'' or ''apron advisory'') to provide coordination between the users. Apron control allocates aircraft parking stands (gates) and communicates this information to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxiway
A taxiway is a path for aircraft at an airport connecting runways with aprons, hangars, terminals and other facilities. They mostly have a hard surface such as asphalt or concrete, although smaller general aviation airports sometimes use gravel or grass. Most airports do not have a specific speed limit for taxiing (though some do). There is a general rule on safe speed based on obstacles. Operators and aircraft manufacturers might have limits. Typical taxi speeds are 20–30 knots (37–56 km/h; 23–35 mph). High-speed exit Busy airports typically construct high-speed or rapid-exit taxiways to allow aircraft to leave the runway at higher speeds. This allows the aircraft to vacate the runway quicker, permitting another to land or take off in a shorter interval of time. This is accomplished by reducing the angle the exiting taxiway intercepts the runway at to 30 degrees, instead of 90 degrees, thus increasing the speed at which the aircraft can exit the runway onto the taxiway. ...

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Tarmac (company)
Tarmac is a British building materials company headquartered in Solihull, England.

Carillion
Carillion plc was a British multinational construction and facilities management services company headquartered in Wolverhampton in the United Kingdom, prior to its liquidation in January 2018. Carillion was created in July 1999, following a demerger from Tarmac. It grew through a series of acquisitions to become the second largest construction company in the United Kingdom, was listed on the London Stock Exchange, and in 2016 had some 43,000 employees (18,257 of them in the United Kingdom). Concerns about Carillion's debt situation were raised in 2015, and after the company experienced financial difficulties in 2017, it went into compulsory liquidation on 15 January 2018, the most drastic procedure in UK insolvency law, with liabilities of almost £7 billion. In the United Kingdom, the insolvency caused project shutdowns and delays in the UK and overseas (PFI projects in Ireland were suspended, while four of Carillion's Canadian businesses sought legal bankruptcy protection) ...

Tarmac Scam
The tarmac scam is a confidence trick in which criminals sell fake or shoddy tarmac (asphalt) and driveway resurfacing. It is particularly common in Europe but practiced worldwide. Other names include tarmacking, the asphalt scam, driveway fraud or similar variants. Non-English names include "" (Italian), "" (German) and "" (French). Method A conman typically goes door-to-door, claiming to be a builder working on a contract who has some leftover tarmac, and offering to pave a driveway at a low cost. The paving is in fact often simply gravel chippings covered with engine oil, or not the right depth and type of materials to form a lasting road surface. Milk has been used to make a fake sealant. The conmen may target elderly, vulnerable residents, and claim to be official contractors working on roadworks to add credibility. Reported escalation has included increasing the cost, claiming that the job has required more material than expected, and making threats. Irish crime repor ...
