Most people think of speed humps as a minor inconvenience. They are much more than that. In car parks, school zones, and residential complexes, they are one of the most effective and affordable ways to reduce vehicle speeds and protect pedestrians.
Most people think of speed humps as a minor inconvenience. They are much more than that. In car parks, school zones, and residential complexes, they are one of the most effective and affordable ways to reduce vehicle speeds and protect pedestrians.
A well-placed speed hump forces drivers to slow down to around 15 to 30 km/h, depending on the design. That kind of speed reduction can be the difference between a near miss and a serious injury, especially in areas where children, elderly residents, or workers on foot are sharing space with vehicles.
For property managers and strata committees, there is also a legal angle. Under Australian tort law, property owners and occupiers owe a duty of care to anyone using their premises. If someone is injured on your site because vehicles were travelling too fast and no reasonable traffic calming measures were in place, you could be looking at a liability claim. Speed humps are a practical and relatively low-cost way to address that risk before it becomes a problem.
Every speed hump installed in an off-street parking facility in Australia needs to comply with Australian Standard AS 2890.1:2004. This is the standard that covers parking facilities, and it lays out very specific requirements for what a speed hump should look like and where it should go.
Here is a summary of the key design criteria under AS 2890.1 for Type 2 speed humps, which are the most common type used in car parks and private properties:
Must be between 25mm and 75mm. Go below that range, and the hump will not slow anyone down. Go above it, and you risk causing vehicle damage or creating an accessibility hazard.
The top of the hump must be flat, not rounded or peaked. A flat top surface between 100mm and 150mm wide is the standard requirement.
The height-to-length ratio should be 1:2 to ensure vehicles transition smoothly over the hump without bottoming out.
Speed humps must have alternating yellow (or white) and black stripes, each 250mm wide. These high-visibility markings are not optional. They are a legal requirement to make sure drivers can see the hump clearly, especially at night or in low-light conditions.
Type 2 speed humps should be spaced at least 10 metres apart along any single aisle or roadway. If you need continuous speed control along a longer stretch, the maximum spacing should be around 50 metres.
Speed humps should be positioned clear of intersections and curved roadways. They also must not block or interfere with pedestrian paths, wheelchair access, or accessible pathways. At least 1 metre of clear travel space is required on either side of the hump when it is near an accessible route.
If a speed hump is not clearly visible to approaching drivers, a W5-10 hump warning sign should be installed. Raised reflective pavement markers may also be required alongside the standard stripe markings.
These are not suggestions. They are compliance requirements. If your speed humps do not meet AS 2890.1, you are potentially exposing yourself to legal risk and insurance headaches.
This is one of the most common questions we hear from property managers, and the answer depends on where the speed humps are going.
In most cases, you do not need a planning permit to install speed humps on private land, as long as the installation complies with AS 2890.1:2004 and any relevant building or safety codes. However, if your property falls under a strata scheme or body corporate, you will almost certainly need approval through the committee before any work begins. Check the by-laws carefully, because they often outline the process for making changes to shared areas like driveways and car parks.
This is a completely different process. Civilians cannot install speed humps on public roads without council approval. Local councils in Melbourne have their own traffic management plans, and any request for speed humps on a public street will go through a formal assessment process. That process usually involves traffic data collection, community consultation, and an evaluation by traffic engineering officers before any recommendation is made.
School grounds and council properties typically have their own procurement and approval processes. If you are a facilities manager at a school or a council asset manager, the process usually involves getting quotes, confirming compliance with AS 2890.1, and coordinating the installation around term breaks or quiet periods to reduce disruption.
If you are unsure about what approvals you need for your specific situation, a quick phone call to your local council's traffic or planning department will usually point you in the right direction. Your asphalt contractor should also be able to advise you on what they have seen in similar projects across Melbourne.
This is the other big question that comes up in almost every speed hump conversation. Both materials have their place, and the right choice really comes down to your site, your budget, and how long you need the speed humps to last.
Asphalt speed humps are built directly into the road surface. A section of the existing pavement is raised using hot-mix asphalt, compacted, and then finished with the required markings.
Strengths: Asphalt humps are extremely durable when properly installed and maintained. They blend seamlessly with the surrounding road surface, which gives a clean and professional look. They handle heavy traffic well and can last 8 to 12 years or longer before needing restoration. For permanent installations on high-traffic roads, car parks, and school access routes, asphalt is often the better long-term choice.
Considerations: Installation does require temporary road closure while the asphalt is laid and compacted. Over time, asphalt can develop cracks or surface wear due to weather exposure and heavy use, so periodic repairs and resurfacing should be factored into your maintenance plan. Melbourne's climate, with its hot summers and wet winters, can accelerate surface wear if drainage around the hump is not handled correctly.
Rubber speed humps are pre-manufactured modular units, typically made from recycled rubber. They are bolted directly onto the existing road surface using concrete or asphalt anchors.
Strengths: Quick and easy to install with minimal disruption. They can be removed and relocated if your traffic management needs change. Rubber humps tend to be quieter than asphalt when vehicles drive over them, which can be a plus for residential settings. They also come with built-in reflective markings in many cases.
Considerations: Rubber humps tend to wear out faster than asphalt, especially in areas with heavy truck traffic or extreme temperature swings. UV exposure can degrade the material over time, and replacement cycles are typically shorter, around 5 to 7 years. They may also shift slightly under heavy loads if not anchored securely, and they do not always sit flush with uneven surfaces.
For permanent, high-traffic installations like shopping centre car parks, school drop-off zones, and industrial sites, asphalt speed humps are generally the stronger option. They integrate with the existing surface, handle heavy loads, and provide lasting value when backed by proper asphalt construction and maintenance.
For temporary setups, seasonal use, or locations where you might need to reposition speed humps down the track, rubber is a practical and cost-effective choice.
If you are still not sure which material is best for your site, an experienced asphalt contractor can assess your surface, traffic patterns, and site conditions and give you a straight recommendation.
People use these terms interchangeably, but they are actually three different things. Knowing the difference matters because each one serves a different purpose.
Speed bumps are shorter and more aggressive. They are typically around 50 to 100mm tall and only 300mm or so wide. They bring vehicles almost to a complete stop and are best suited for very low-speed areas like underground car parks and private driveways.
Speed humps are wider and more gradual. They span a larger portion of the road width and are designed to slow traffic to around 15 to 30 km/h without the jarring stop-start effect. They are the most common choice for car parks, school zones, and residential streets.
Speed tables are essentially elongated speed humps with a flat top that can double as a raised pedestrian crossing. They are more expensive to install but are ideal for high-visibility crosswalk areas where you want to both slow traffic and provide a safe crossing point.
For most Melbourne property managers, speed humps hit the sweet spot between effectiveness and practicality. But if you are working on a car park design that includes pedestrian crossings, a speed table might be worth considering as well.
This is the question that keeps property managers and strata committees up at night. Nobody wants a car park shut down for days on end or residents unable to get to their parking spots.
The good news is that speed hump installation is a relatively quick process. For asphalt speed humps, most jobs can be completed within a day, depending on how many humps are being installed and the size of the site. There will be a short curing period after the asphalt is laid, but experienced contractors plan the work so that traffic can be redirected within the site during the process.
Rubber speed humps are even faster. They can typically be installed in a few hours since they are bolted down onto the existing surface without any need for heavy machinery or curing time.
For school grounds, the smartest approach is to schedule the work during school holidays or on weekends when the site is quiet. The same goes for commercial car parks. A Friday afternoon install, for example, can give the asphalt time to cure over the weekend so the car park is back in full operation by Monday morning.
At MR Asphalt, we have been doing this for over 30 years across Melbourne's south-eastern suburbs, the Mornington Peninsula, and South Gippsland. We plan every speed hump job to keep disruption to a minimum, and we work closely with property managers and facilities teams to schedule around their peak usage times.
Based on what we have seen across hundreds of projects, here are a few things that trip people up when it comes to speed hump installation:
There are a lot of low-cost rubber speed humps on the market that are made from poor quality recycled materials. They fade quickly in Australian sun, break down under heavy traffic, and often fail to meet the required height, ramp angle, or marking standards. You might save a few dollars upfront, but you will pay for it in replacements and potential liability.
Even if your council does not require a formal permit for a private installation, your speed humps still need to meet AS 2890.1. Insurance claims and liability disputes will almost always reference whether the installation met the relevant Australian Standards.
Speed humps installed too close to intersections, on curves, or blocking accessible pathways create more problems than they solve. Placement needs to be thought through carefully, ideally by someone who has done it before and understands site-specific factors like drainage, visibility, and traffic flow.
Like any asphalt or rubber surface, speed humps need periodic inspection and maintenance. Cracked or faded markings, loose rubber modules, and surface wear should all be addressed promptly. If a speed hump is not visible or functional, it is worse than not having one at all, because it creates a false sense of security.
Generally yes, as long as the installation is on private property and meets AS 2890.1. However, you will need approval from your owners' corporation or body corporate committee before proceeding.
That depends on the layout, the length of the roadway, and where the high-risk areas are. As a starting point, Type 2 speed humps should be spaced no closer than 10 metres apart and no further than 50 metres apart for continuous speed control. An on-site assessment will give you a more accurate answer.
Not if they are designed and installed correctly within the AS 2890.1 height range of 25mm to 75mm. The standard is specifically designed to slow vehicles without causing damage when drivers travel at the intended speed.
This is worth discussing with your local fire brigade or ambulance service, especially for larger complexes. Speed cushions, which are narrower speed humps with gaps that allow wider emergency vehicles to pass through without slowing down, can be a good alternative in some situations.
With proper installation and regular maintenance, asphalt speed humps can last 8 to 12 years or more. Factors like traffic volume, drainage, and Melbourne's variable weather all play a role in their lifespan.
Speed humps might look simple, but getting them right requires proper base preparation, accurate profiling, compliant markings, and an understanding of how traffic flows through your specific site. A contractor who specialises in asphalt construction and repair will know how to handle all of those details so that you end up with speed humps that actually do their job and last.
