Asphalt Driveways & Paths
Asphalt paving requires specialist hot-mix equipment and is not a DIY task. This guide explains what contractors do, what to specify, and how to get an accurate quote.
Where asphalt is used
Driveways
Most common residential use — handles vehicle load well
Thickness: 40–60 mm
Paths & patios
Pedestrian surfaces, garden paths
Thickness: 25–40 mm
Parking areas
Heavy use, heavier vehicle loads
Thickness: 60–80 mm
What the job involves
Site preparation
The contractor removes existing surfaces (soil, gravel, old concrete) and excavates to the required depth — typically 250–300 mm total for a driveway.
Edges are formed to give a clean boundary. Existing drainage must be checked and adjusted.
Sub-base installation
A layer of compacted crushed stone (pukk/grus) is laid — typically 100–200 mm. This provides structural support and drainage. The sub-base is compacted using a plate compactor or roller.
Asphalt laying
Hot-mix asphalt is delivered in trucks from the asphalt plant (typically 3–8 km away) and must be laid within 30–60 minutes before it cools. A mechanical paver spreads the mix to an even thickness.
For residential driveways, 40–60 mm is standard. Thicker layers may be laid in two passes.
Compaction & finishing
A road roller compacts the asphalt to achieve the final thickness and density. Edge compaction is done by hand-roller. New asphalt needs to cool before use — often a few hours for foot traffic and around a day before normal car use — but it keeps hardening for weeks. During that time avoid parking in the same spot for long periods, sharp turning of stationary wheels, and point loads (jacks, stands, trailer legs), and expect it to stay softer in hot weather. Follow the contractor's specific advice.

Tools you'll need
The kit this job actually calls for, and whether it's worth buying or renting for one weekend.
- Tape measure
This is a contractor job — these are the tools for specifying and checking it, not laying it.
Buy 8–20 € - String line and pegs
Check the finished levels and falls against your set-out.
Buy 5–15 € - Screed board / straightedge
Lay it across the finished surface to find ponding hollows before you sign off.
Buy 20–60 € - Spirit level
Confirm the fall runs away from the house, not toward it.
Buy 15–60 €
Prices are indicative for DIY-grade tools and vary a lot by brand and region — treat them as a budgeting starting point, not a quote. Rental rates are per day from a typical tool rental shop.
Frequently asked questions
How thick should a driveway asphalt layer be?
For a residential driveway: 40–60 mm of asphalt on top of a 100–200 mm compacted crushed stone base. Paths and patios with no vehicle traffic can use 25–40 mm.
Can I lay asphalt myself?
No. Hot-mix asphalt requires specialist paving equipment (pavers and rollers) and must be laid while the mix is hot (140–180°C). This is strictly contractor work. Cold-mix patching products exist for small repairs only.
How do I calculate how many tonnes I need?
Volume (m³) = area × thickness. Weight (tonnes) = volume × 2.3 (asphalt density is ~2300 kg/m³). Our calculator does this automatically.
What should I ask a contractor before getting a quote?
Ask: What base preparation is included? Will you remove the existing surface? What thickness do you recommend for my use? What warranty do you offer? How many tonnes will you use (you can verify with this calculator)?
How long does asphalt last?
A well-laid residential driveway lasts around 20–30 years, helped most by good drainage and prompt crack/pothole repair. Sealcoating every few years is common practice in some regions (notably North America) but is not standard everywhere — in many European/Nordic climates it is rarely used — so treat it as a regional option and follow local practice.
