Asphalt Mixing Plant – Construction Equipment

Nowadays every country wants to enhance their economical strength more strong and powerful that is why almost each country is mainly focusing on construction of strong infrastructure of entire nation. It is true fact that strong and attractive powerful infrastructure can easily review the economical development of any country. Here strong infrastructure is referring to construction of good quality roads, and larger buildings.

There are too many objects units together to form good and strong quality roads. Among all objects, it is construction machineries like Asphalt Mixing Plant which plays significant and vital role in providing the strong forms of roads. Asphalt Mixing Plant is equipment in which various raw materials like sand, asphalt, filler, macadam, and dust particles are aggregates and combined together under accurate temperature to form strong and quality form.

Realizing about great importance and value of Asphalt mixing plant in construction of strong infrastructure different manufacturing companies has make their best effort to facilitate the market with various categories of it products. Today you can get different categories of it. Some of the names of categories are described below: -

Asphalt Drum Mix Plant

Asphalt Batch Mix Plant

Mobile Hot Mix Plant

Soil Stabilisation (Wet Mix) Plant

Mobile Concrete Plant

But before going for any categories you must closely notice about the parts and features which are implemented in Asphalt mixing Plant. You must also notice whether brand mark like ISI Certification marks are implemented on different parts of asphalt mixing plant are present or not. Only satisfying with its features you can make purchase for getting maximum satisfaction.

7 Ways Profit From Asphalt and Highway Construction

By Guest Author: Robert Williams, PhD, P.E.

There is a dominant stock investing theme that directs you to invest in companies that provide a product that everybody uses every day. May I draw your attention to a specific product in this category, namely asphalt? Unless your house has a tile roof, you probably woke up under an asphalt-tiled roof; walked to your car on an asphalt footpath; drove your car to work on an asphalt-surface highway or freeway; and parked your car in the asphalt-surface office car park.

In addition, President Obama is going to re-surface all of the US deteriorating freeways and highways – using asphalt of course.

You may wish to consider investing in some of the asphalt companies identified in this article. However, most asphalt involved companies are large conglomerates and certainly the asphalt producers are the major oil and gas conglomerates some of which are listed below.

If you have not even thought of where the asphalt comes from you should be aware that it is derived from crude oil refining which primarily produces your gasoline and diesel which you also use every day.

In order to be ready for road surfacing asphalt needs to be transported from the refineries to road construction companies that combine it with various rock aggregates to provide the hard surface that you drive on. This thick black substance is only liquid at temperatures above 300 degrees Fahrenheit and requires specially designed and dedicated trucks to transport the asphalt while maintaining its temperature. I have been involved with various refinery automation projects including asphalt truck loading racks where asphalt is sold by refinery truck weigh scales (weight out minus weight in) with computer controlled and data processing for product loading authorization and custody transfer accounting/ billing for each load.

If we have international readers you should be aware that we are talking about bitumen, but not tarmac or coal tar. Tar is derived from coal and was the original road surfacing material when it was available from coal gas processing which has long been replaced by natural gas. These coal tar roads date back to the early 1800’s when John McAdam started the road surfacing referred to as tarmac or macadam roads.

Apart from the major oil companies shown in group stock charts as asphalt producers there are a large number of privately- and publicly-owned companies involved in getting the asphalt onto the roads, or car parks, or roofs. Some of these non-private companies are listed here with a brief description and their earnings estimates. According to your personalized investing criteria listed in your Trading Plan you should evaluate and exercise your due diligence as to potential investment opportunities. This is who, what, where, why and how but not the when. At this time the author has no investments in any of these companies.

Distillation Oil Refining

Crude oil, also called petroleum, is a complex mixture of carbon and hydrogen (hydrocarbons), which exist as a liquid in the earth's crust. Crude oil has many compositions, some is black, thick and tar like, while other crude oils are lighter in color and thinner. The carbon and hydrogen in crude oil are thought to have originated from the remains of microscopic marine organisms that were deposited at the bottom of seas and oceans and was transformed at high temperature and pressure into crude oil and natural gas.



This oil and gas migrates upward through the porous rock, as it is less dense than the water which fills the pores. The oil and gas is trapped by a layer of impermeable rock through which they can't flow. Several different types of oil and gas "traps" exist; a common dome formed by folded sedimentary rocks. Crude oil is obtained by drilling a hole into the reservoir rock (sandstone, limestone etc.) and pumping it out.

Petroleum refining is the process of separating the many compounds present in crude petroleum. This process is called fractional distillation where the crude oil is heated; the various of the compounds boil at different temperatures and change to gases; and are later recondensed back into liquids. Fossil Fuels

The principle which is used is that the longer the carbon chain, the higher the temperature at which the compounds will boil.
Boiling Points and Hydrocarbons

The crude petroleum is heated and changed into a gas. The gases are passed through a distillation column which becomes cooler as the height increases. See the figure on the left. When a compound in the gaseous state cools below its boiling point, it condenses into a liquid. The liquids may be drawn off the distilling column at various heights.
Although all fractions of petroleum find uses, the greatest demand is for gasoline. One barrel of crude petroleum contains only 25-35% gasoline. Transportation demands require that over 50% of the crude oil be converted into gasoline. To meet this demand some petroleum fractions must be converted to gasoline. This may be done by "cracking" - breaking down large molecules of heavy heating oil; "reforming" - changing molecular structures of low quality gasoline molecules; or "polymerization" - forming longer molecules from smaller ones. Conversion Oil Refining
For example if decane is heated to about 500 C the covalent carbon-carbon bonds begin to break during the cracking process. Many kinds of compounds including alkenes are made during the cracking process. Alkenes are formed because there are not enough hydrogens to saturate all bonding positions after the carbon-carbon bonds are broken.
