What is a Gravel Driveway ?

What is a gravel driveway ?

Gravel is a French word meaning coarse sand.

Gravel is a natural deposited Material native not to all areas of the U.S.

Gravel is not “ topsoil—fill dirt sub soil—washed stone—crushed stone or clay soil “.

Large gravel deposits where formed as a result of weathering and erosion and the great ice age glacier where natural deposits were formed.

These deposits are commonly known bank gravel, sometimes called, bank run gravel, is found with stones, clay, sand and silt that is what is dug up from the bank.

Driveway gravel is generally a gravel of a finer material, sized finer with a sand mixture or a silt gravel mixture found naturally as bank gravel.

Another good gravel for driveways is a processed or screened gravel, this gravel is screened and sized  removing all large oversize material, making a finer product, this product is often used for D.O.T. projects and other construction projects.

If properly constructed and maintained a gravel driveway is an all weather driveway.

Gravel driveways generally are quite inexpensive to build compared to an asphalt driveway.

Gravel driveways are constructed by removing the topsoil and subsoil down to the firm layer of ground, then gravel is placed in layers and compacted to proper thickness generally 12”, this is a good driveway gravel base, generally this base can handle heavy traffic even during construction times if properly installed.

Proper grading and drainage are important for the long life of a gravel driveway.

A gravel driveway is also a very eco and green environmental friendly way to place a drive in a wooded area or other county settings.

Gravel driveways are great for the average home, gravel driveways can also be used as a heavy commercial traffic drive and have a long life with proper maintenance.

What is Blacktop ?

What is blacktop ?

Generally today blacktop is used for all types of road construction and surfacing or resurfacing highways and streets.

Blacktop is a black bituminous material used for paving roadways—streets—parking lots and other surfaces that require a hard permanent surface.

The first blacktop was used for paving streets was about 1875, this street was paved with blacktop placed on the street in front of the court house in Newark, New Jersey, this was the first blacktop used in the United States, blacktop was used overseas long before it was used in the U.S.

There were many patents filed for the process of making blacktop from refining crude oil petroleum into an blacktop base oil, then mixing the oil with sized aggregate material.

Blacktop plants were invented around 1899, they were first installed in cities, it was believed the first was in Cambridge, Mass.

Blacktop has been known by many names—-asphalt—tarmac—asphalt concrete— bituminous concrete.

Blacktop today is generally made in a drum plant, the aggregate materials and petroleum based oil are heated to a high temperature generally above 250 degrees F. this method is known as a in place type plant, where the blacktop after mixing is generally a hot-laid type blacktop used for road surfaces.

The advantage to a hot-laid type blacktop, it is easy to work or lay down, installs as a smooth road surface. Also the blacktop mixture can be transported in dump trucks many miles from the plant to the work site.

The hot-laid blacktop is made of different sizes of aggregate for different types of uses in the building of a roadway, the base type blacktop has larger aggregate and the top type blacktop uses a smaller type aggregate for a smooth blacktop surface when completed.

Today paving is generally all hot mix blacktop, this material is easy to lay down using a modern blacktop paver, the blacktop is rolled in place and as the blacktop cools it becomes hard like concrete.

There are many types of blacktop today and there are many different uses for the blacktop produced.

What is a construction project survey ?

Contractors use an engineer project survey plan when working on a construction project. Projects nust have a layout by a surveyor to plot the project construction begins when space is limited and a property boundary needs to be located before the start of the boulding project at the proper location.

Project survey will locate existing underground utilities services—gas lines—electric lines—sewer lines—water lines—storm drainage lines—before construction begins.

A project survey will locate existing property lines and any property right of way, this is needed when the engineer and contractor plot the new project.

Project surveys are helpful when design of a new project is being engienered as road design—utility design—land development—mall layouts—boundary survey—topographic survey—lighting design—irrigation—wet land design—traffic design and design build survey.

Landscape contractor use a project survey to layout and install drainage lines—driveways—rock walls—sidewalks—backyard waterfalls—stone design—swimming pools and landscape projects.

Modern technology is often used when preparing a new excavating construction site plan with 3D- site modeling, a computer generated software package designed for the excavating and construction field, which is an over view of any construction project.

Do-it-yourselfers can use a project survey layout design for home projects and maintenance project. the tools you will need can generally be rented from a local rental company or purchase from a local dealer.
