Depending on the temperature used there are emissions of various intensities of polycyclic aromatic hydrocarbons (PAH), some of which are carcinogenic.

What is tar used for in Namibia?

It is used as a base for coatings and paint, in roofing and paving, and as a binder in asphalt products. Both coal tar and coal-tar pitch contain many chemical compounds, including carcinogens such as benzene.

Why is tar so sticky?

How is tar laid in Namibia?

Essentially, laying a tarmac driveway involves excavating the area to create a solid base, laying edging stones or kerbs, installing a compacted sub base of aggregate, laying a compacted binder course and then finishing of by laying a top coat or wearing coat that is also compacted down.
