Hello everyone,
I mentioned this briefly in another thread, but I think this part belongs here.
We are facing the decision of whether to buy and renovate a 1960s house or not. Unfortunately, the plot was previously covered by a Dutch tar company with nearly 200 sqm (2,150 sq ft) of tar.
Does anyone have experience with these tar layers? We estimate that the mixture exceeds limit values and is classified as "tar-containing," and that the layer is about 8-10 cm (3-4 inches) thick. As far as I can tell, breaking it up isn’t the biggest challenge – disposal is probably much more complex, right?
Does anyone have a rough price estimate for something like this? Assuming we have 200 sqm (2,150 sq ft) of 10 cm (4 inches) tar-containing asphalt on top of gravel only. We want to remove and dispose of the asphalt. If we consider only the asphalt, that’s roughly 20 m³ (700 cubic feet), so a large container.
What price range are we talking about for demolition and disposal? Could this be managed within 5,000 - 8,000 €?
Thanks very much for your help.

Keep dreaming

This forum is just really into numbers.

Keep dreamingTo be honest, I don’t really care. I follow the rules carefully and trust that the authorities will take sensible measures against faulty construction and toxic building materials. Whether the disposal site then recycles it is beyond my control.
But I think this discussion isn’t really necessary—you can simply take your materials to the concrete batching plant when needed and try it out.

This forum is just cool about numbers. Exactly. And until now, the material had to be reused where it was removed. This is now changing, and everything must be disposed of. Just because a road is black doesn’t mean it’s tar.
But since you know it so well as a service technician, I simply advise you to dispose of your tar that way and potentially have to dispose of and pay for tens of thousands of tons.

Basically, a distinction is made between tar- or pitch-containing asphalt and bitumen-based asphalt. Tar- or pitch-containing asphalt contains so-called PAHs (polycyclic aromatic hydrocarbons), whereas bitumen-based asphalt does not. In Germany, since the 1970s, tar- or pitch-based asphalt has been banned in public road construction due to its carcinogenic potential and must be fully replaced by bitumen.

The highest-value recycling, meaning the reuse of reclaimed asphalt pavement in the production of asphalt mixtures (using the hot mix process), is legally required as well as economically, environmentally, and technically beneficial. For this reason, it has been state of the art in Germany for years and is embedded in the technical regulations for asphalt.
It goes without saying that the whole process is tar-free.
