Asphalt 

 

Base layer of Asphalt concrete in a road under construction.

Asphalt ( ˈæs.fɒlt is a sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleums and in some natural deposits sometimes termed asphaltum. It is most commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase (though there is some disagreement amongst chemists regarding its structure).

In U.S. terminology, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside North America, the product is called bitumen.

The primary use of asphalt is in road construction, where it is used as the glue or binder for the aggregate particles. The road surfacing material is usually called ' asphaltic concrete' or simply AC in North America, or simply 'asphalt' elsewhere. Within North America the apparent interchangeability of the words 'asphalt' and 'bitumen' causes confusion outside the road construction industry despite quite clear definitions within industry circles.

Catch Basin

A storm drain, storm sewer (U.S.), stormwater drain (Australia and New Zealand) or surface water system (UK) is designed to drain excess rain and ground water from paved streets, parking lots, sidewalks, and roofs.  Storm drains vary in design from small residential dry wells to large municipal systems. They are fed by street gutters on most motorways, freeways and other busy roads, as well as towns in areas which experience heavy rainfall, flooding and coastal towns which experience regular storms.

Concrete

Concrete is a construction material composed of cement (commonly Portland cement) as well as other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate such as gravel, limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures. The word concrete comes from the Latin word "concretus", which means "hardened" or "hard".

Concrete solidifies and hardens after mixing with water and placement due to a chemical process known as hydration. The water reacts with the cement, which bonds the other components together, eventually creating a stone-like material. Concrete is used to make pavements, architectural structures, foundations, motorways/roads, bridges/overpasses, parking structures, etc.

Curb

Curb (road), or kerb, the edge where a raised pavement/sidewalk/footpath, road median, or road shoulder meets an unraised street or other roadway.

Typically made from concrete, asphalt or long stones (often granite), the purpose is twofold: first as a gutter for proper drainage of the roadway, and second for safety, to prevent motorists from driving onto the shoulder, median, sidewalk, or pavement.

Parking Lot

A Parking lot (called a car park in countries such as Malaysia, Australia, the UK, and Ireland), also known as "car lot," is a cleared area that is more or less level and is intended for parking vehicles. Usually, the term refers to a dedicated area that has been provided with a durable or semi-durable surface.

The usual parking lot is paved with asphalt. Some are paved with concrete. Many are gravel lots. A few of the newer lots are surfaced with permeable paving materials.

Parking lots have their own special type of engineering. While parking lots have traditionally been an overlooked element of development projects by governmental oversight, the recent trend has been to provide regulations for the configuration and spacing of parking lots, their landscaping, and drainage and pollution abatement issues.

Pave, Paving

Road surface (British English) or pavement (American English) is the durable surface material laid down on an area intended to sustain traffic (vehicular or foot traffic). Such surfaces are frequently marked to guide traffic. The most common modern paving methods are asphalt and concrete. In the past, brick was extensively used, as was metalling. Today, permeable paving methods are beginning to be used more for low-impact roadways and walkways.

Sidewalks

A sidewalk (chiefly North American English), pavement (British English, South African English and Philadelphia dialect), footpath (Australian English, Irish English, Indian English and New Zealand English) or footway (Engineering term) is a path for pedestrians that is situated alongside a road or formed like sidewalks that are alongside roads (such as a concrete footpath through a park).

A sidewalk may accommodate moderate changes in grade. However, "walkway" is a more complete term for support of walking, and includes stairs, ramps, paseos (passageways) and related off-street tools that provide for a developed pathway.

Sometimes, a sidewalk is next to its street or road with perhaps only a curb in between. Sometimes, there is an area called a parkway or tree lawn in between the sidewalk and the street.

In the United States, the most common type of sidewalk consists of a poured concrete ribbon with cross-lying strain relief grooves at intervals of ~1 m; this is intended to minimize visible damage from tectonic and temperature fluctuations, both of which can crack longer segments. However, freeze-thaw cycles (in cold-weather regions) and tree root growth can eventually result in damage which requires repair. Brick sidewalks are found in some urban areas, usually for aesthetic purposes.

Speed Bumps

A speed bump (in British English a speed hump, road hump or sleeping policeman) is a velocity-reducing feature of road design to slow traffic or reduce through traffic.

A speed bump is a bump in a roadway with heights typically ranging between 3 to 4 inches (7 to 10 cm).

The length of speed bumps are typically less than or near to 1 foot (30 cm); whereas speed humps are longer and are typically 10 to 14 feet (3 to 4 m) in length.

The use of speed bumps is widespread around the world, and they are most commonly found where vehicle speeds are statutorially mandated to be low.

Although speed bumps are very effective in keeping vehicle speed down, their use is sometimes controversial as they can cause noise and possibly vehicle damage if taken at too great a speed.

Poorly designed speed bumps often found in private car parks (too tall, too sharp an angle for the expected speed) can be hard to negotiate in vehicles with low ground clearance, such as sports cars, even at very slow speeds. Speed bumps can also pose serious hazards to motorcyclists and bicyclists if not easily noticed.

Tennis Courts

A tennis court is where the game of tennis is played. It is a firm rectangular surface with a low net stretched across the center.

Tennis is played on a rectangular flat surface, usually of grass, clay, concrete (hard court) or a synthetic suspended court. The court is 78 feet (23.78 m) long, and its width is 27 feet (8.23 m) for singles matches and 36 feet (10.98 m) for doubles matches.  Additional clear space around the court is needed in order for players to reach overrun balls for a total of 60 feet (18.3 m) wide and 120 feet (36.7 m) long. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is 3 feet 6 inches (1.07 m) high at the posts, and 3 feet (920 mm) high in the center.

Hard courts, usually made of asphalt, are considered "medium" surfaces, where fast hard-hitting players have a slight advantage. Hard courts can vary in speed, they are faster than clay but slower than grass courts, which allow the ball to slide.

Trench Drain

A trench drain (also channel drain, line drain, or strip drain) is a specific type of floor drain containing a dominant trough- or channel-shaped body. I

t is used for the rapid evacuation of surface water or for the containment of utility lines or chemical spills. Employing a solid cover or grating that is flush with the adjoining surface, this drain is commonly made of concrete in-situ and may utilize polymer- or metal-based liners or a channel former to aid in channel crafting and slope formation.

Characterized by its long length and narrow width, the cross-section of the drain is a function of the maximum flow volume anticipated from the surrounding surface. Channels can range from 1 inch to 2 feet in width, with depths that can reach 4 feet.

Trench drains are commonly confused with french drains, which consist of a perforated pipe that is buried in a gravel bed, and which are used to evacuate ground water.

A slot drain, also wrongly associated with a trench drain, and consists of a drainage pipe with a thin neck (or slot) that opens at the ground surface with sufficient opening to drain stormwater.
