(Entry 1 of 2) 1 : a dark bituminous substance that is found in natural beds and is also obtained as a residue in petroleum refining and that consists chiefly of hydrocarbons. 2 : an asphaltic composition used for pavements and as a waterproof cement.

Bitumen is actually the liquid binder that holds asphalt together. The term bitumen is often mistakenly used to describe asphalt. A bitumen-sealed road has a layer of bitumen sprayed and then covered with an aggregate. Asphalt results in a smoother and more durable asphalt road surface than a bitumen-sealed road.

1 : a thick dark sticky liquid made from wood, coal, or peat. 2 : a substance (as one formed by burning tobacco) that resembles tar. tar. verb. tarred; tarring.

The tar command is used to compress a group of files into an archive. The command is also used to extract, maintain, or modify tar archives. Tar archives combine multiple files and/or directories together into a single file. Tar archives are not necessarily compressed but they can be.

Tar (Tape Archive) is a UNIX utility program that combines multiple files into a single file. The resulting file has a . tar extension. .tar file contains any number of individual files plus information to allow them to be restored to their original form.

The term ZIP is an acronym for Zone Improvement Plan; it was chosen to suggest that the mail travels more efficiently and quickly (zipping along) when senders use the code in the postal address.

What is another word for asphalt?

blacktop	tar
tarmac	bitumen
macadam	pitch
concrete	pavement

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.

The materials that are used to make blacktop and asphalt are the same. Both are made from two ingredients: bitumen and crushed stone. The difference lies in how those ingredients are combined to make the final product.

Lower upfront cost: Asphalt is less expensive than concrete to install. It could be about half the price per square foot to install asphalt. When installing an asphalt driveway, all you need to do to replace it is add a new layer instead of reconstructing the existing base.

The main difference between Tar and Asphalt is that the Tar is a substance and Asphalt is a sticky, black and highly viscous liquid or semi-solid form of petroleum; bitumen variety. Tar can be produced from coal, wood, petroleum, or peat.

Tar-and-Chip Driveway Cost A tar-and-chip driveway will typically cost about twice as much as a gravel driveway and a little less than an asphalt driveway. Expect to pay in the range of $2 to $5 per square foot (the exact cost will vary depending on your region and the labor costs in your community).

The two substances are very similar and sometimes the terms tar and bitumen are used interchangeably. Bitumen can be naturally occurring whereas tar usually has to be artificially distilled. Also, Bitumen occurs in both solid and liquid forms whereas tar is generally always a viscous liquid.

The word asphalt comes from the Greek “asphaltos,” meaning “secure.” The Romans used it to seal their baths, reservoirs and aqueducts. Europeans exploring the New World discovered natural deposits of asphalt.

Asphalt is one of the oldest engineering materials known to man, dating as far back as 2600 B.C. when the ancient Egyptians used it as a waterproofing agent and preservative for the wrappings of mummies. While natural asphalts were widely used until the early 20th century, today most asphalt is refined from crude oil.

Asphalt is easier to repair than concrete but needs it more frequently. While both asphalt and concrete crack, asphalt tends to deteriorate faster due to its softer consistency. However, it’s fairly easy to repair cracks and damage in asphalt, and the repaired areas generally blend well with the rest of the driveway.

Asphalt uses much less aggregate material than tarmac, but requires more machinery and manpower to lay it down. Asphalt’s lower aggregate composition, however, means it is more susceptible to weather damage and more easily corroded by oil products. Fortunately, it’s also easier to maintain and repair than tarmac.

Which product is cheaper? For smaller surfaces, asphalt is slightly more expensive than tarmac. However, it is also harder wearing, making it more resistant to various weather conditions which in the long run, makes the product more cost effective.

2. Gravel. This is one of the cheapest alternatives to asphalt driveways by far, costing very little to have installed. The average gravel driveway consists of hard, angular gravel laid throughout the driveway.

Asphalt is another popular choice when it comes to installing a new driveway. Cost: Asphalt driveways are cheaper to install than concrete driveways. Therefore those looking for the properties of a concrete driveway but at a cheaper cost, use asphalt as an alternative.

Low-Maintenance Driveway Options

1. Paving Stones. Paving stones are known to last up to a full century if properly laid.
2. Concrete Grass Pavers. An interlocking concrete grass paver driveway made may be an option for your driveway.
3. Plastic Permeable Pavers.

A gravel driveway is by far the cheapest and quickest to install, especially if the existing driveway sub-base is sound.

Steps to build a driveway:

1. Check for underground utilities.
2. Survey your land and know your boundaries.
3. Mark your project area and stake out boundaries.
4. Excavate topsoil and level out project area.
5. Lay wooden forms around the project area, anchored with stakes.
