Asphalt, a natural building material with a centuries-old tradition

The paving of land or paths is not necessarily part of the home improvement repertoire. Nevertheless, we would like to invite you with our guide article to some facts and hints in dealing with the natural building material asphalt, which is wrongly suspected to be a uniform building material.

Asphalting for home use?

That asphalt has been the ideal building material for road, path or parking lot construction for many generations - no question. But what role does that play? Asphalting today in the do-it-yourself area on your own property? Does anyone really need a tarred road in the middle of his estate, which may even be built by himself? We are sure to present a niche topic within home improvement with this special article. But: Quite so far are paved areas on their own land and within real estate - for example, on floors - now not. So on and with the bike trailer off to the mixer?

A building material already used by the Babylonians

Who wants to create a slightly larger area with asphalt and use permanently, will be without the Cooperation with a specialized company but do not get along. And who now thinks of cold asphalt from the building materials trade: This is at best suitable for mini-surfaces, such as enclosing manhole covers or even in the case of minor repairs and repairs already existing and brittle become asphalt pavements or potholes. So that our visitors can read on, where the term asphalt only evokes associations with a foul-smelling, black bitumen mass, a small one Trip to the history of the ancient natural building material, It was about three thousand years before our era, when people of the ancient civilizations of Bitumen (which came very close to today's asphalt) used to build their houses, roads or dams.

Organic material changes from sludge to petroleum

And for this biological process, millions of years and tons of seaweed and microorganisms were known to be needed before finally eligible and eligible oil could arise. Nevertheless, it is still a long way from here to the finished asphalt for the entrance to the property, because for bitumen production it is important to have particularly heavy substances available, the so-called crude oil. The starting material for the building material asphalt must thus beforehand Water, sand and salt removed before being transported to refineries for further processing and refining.

From crude oil to long-lasting and weather-resistant bitumen

Through a multi-level and technologically right elaborate distillation process and with much atmospheric pressure In the refinery, a number of different types of bitumen are initially produced, which are then further processed in a mixing plant and taking into account the later intended use for the final product asphalt. Ultimately, it makes a difference whether later a highly resilient, eight-lane highway or a color-contrasted promenade path should arise within a small garden area. Even with varying quality requirements, asphalt still only consists of:

  • bitumen
  • additional rocks (sand, gravel, grit)
  • Cavities and
  • NO tar (since 1970!)

After multiple drying and heating in Heißbecherwerken and parallel drums done for Completion of asphalt production the loading in silo or tipping vehicles and the transport to the prepared construction site.

Solid basis for the new asphalt pavement

For example, many landowners are tarm- ing their carport floor or the roads there to the one suffering Weed growth in the summer to avoid and in winter the snow particularly easy to eliminate. So that no cracks or subsidence occur in the soil later and for as many years as possible, a generous layer of earth must be removed before the planned asphalting - as is the case with a concrete slab - and the underlying soil layer must be accurately straightened and compacted. However, which preparatory work for the subsoil has to be done concretely depends to a large extent on the conditions at your location. In addition, for the Construction of asphalted surfaces not only requires special knowledge but also machinery, which only specialist companies have.

Asphalt or rather grit, gravel & Co.?

First let's look at a brief comparison that gives you the Differences of asphalt over other materials for road construction or for use on the surface:

Gravel, gravel or grit- little work - low construction costs - no separate drainage needed- Very high cleaning effort - Risk of paint damage - susceptible to weed growth
paving stones- pleasant appearance - simple and accurate surface adaptation - acceptable construction costs- Labor-intensive cleaning - complicated weed removal
Cement, concrete- low construction costs - easy and fast cleaning - different colors possible- separate drainage required - risk of slipping and rapid aging (sealing appropriate)
asphalt- excellent opportunities for care and Cleaning - robustness and long life - elastic footfall sound insulation - color installation possible - color design possible- separate drainage necessary - high construction costs - complex preparatory work - cooperation with special companies required

With shaker, automatic leveling and paver to the new asphalt road

Not only that the flooring for Asphalting with special trucks be used for the installation of the mix even expensive machines needed, Depending on the place of residence, this part can be taken over by a gardening and landscaping company, otherwise municipal companies, road construction companies and plaster makers have such technology and appropriately trained operating personnel. Small road pavers equipped with laser receivers and sensors capable of picking up the asphalt directly from the truck in a special pick-up bucket provide excellent flatness and performance no manual work while asphalting of areas or paths. Here is a brief summary of the facts about a particularly productive paver for smaller projects on private properties on the example of the SUPER 800 of the Baumaschinenmarke Vögele:

  • Pave width: 0.5 to 3.2 meters
  • Engine power: 42 kW
  • Installation capacity: maximum 250 tons per hour
  • Transport length: 4.36 meters
  • Installation thickness when asphalting: maximum 20 cm
  • Passage width: 1.20 meters

Incidentally, this user-friendly device can also be used (after brief instruction!) By people who have never worked with a paver before. Since the processing of Asphalt, however, is not completely safe, we nevertheless recommend that you get involved with a specialist company.

There are some very good reasons for using asphalt

Although for the sake of completeness it must be said that the actual many Advantages of asphalting not all in the private road or surface construction, but rather in public roads or the Construction of large squares have their permission. In addition to the dynamics, in terms of their adaptability to critical loads, the noise poverty as well as the mobility assurance for traffic on the road, asphalting in the private sector compared to other floor coverings quite some notable advantages.

The environmentally friendly asphalt is colorable

This essential environmental aspect is not only because Asphalt a 100% natural product is. In addition, dismantled asphalt can even be completely removed residue-free and completely recyclable, The material thus obtained can be easily mixed with new asphalt and can be used in this form, for example, for the attachment of paths and lanes. Incidentally, the different colors that can be perceived in public places in asphalting are not necessarily based on the addition of chemical color concentrates or solvents. This certainly attractive appearance Mainly by the addition of colored mixing components (for example, fine stone, sand or gravel) in the context of the production process, preferably in red, gray, yellow and green, possible.

Tips & Tricks

In the interest of a high quality of asphalting, this work should be done in dry weather, if possible. The ambient temperature must not fall below freezing, so the best time to install asphalt in spring or early summer is.
