Asphalt is a by-product of the fuel making process so it is actually the ultimate in recycling. If the resultant sludge from oil refining was not used as asphalt we would have to find some other way of disposing of it. Also, as asphalt is porous it is less damaging to the groundwater and natural drainage systems. Like a lawn it’s a bit of a carbon sink too whereas concrete is not. As well as roads and airfields, asphalt is also used as an environmental liner for landfills, reservoirs, and fish hatchery ponds. And lastly asphalt is 100% recyclable and very little ever makes its way into landfill as waste.

In the old days we used to make roads from concrete – but no more. Why? Firstly asphalt is much cheaper than concrete and can be laid a lot quicker. Concrete needs to cure but asphalt can be driven on almost immediately. This also makes the repair process extremely fast and cost effective. Asphalt also responds better to harsh weather conditions making roads less slippery and less likely to “plane” in the wet therefore safer. It’s also able to expand and contract in the heat. It does not need expansion joints like concrete does as asphalt is more likely to just bend rather than break. Both surfaces are subject to cracking and rutting but asphalt is easier to fix and maintain and will stay looking better for longer.

Unlike concrete, asphalt is not a slippery surface even when wet. Water pools are unlikely to form even when the area is very “lumpy”. Unlike concrete, water pooling in an asphalt surface will quickly dissipate leaving the surface dry and safe.
If you have ever seen spoon drains in concrete you’ll know that water will sit for days depending on evaporation to dry it out. Meanwhile, mould will form and a slippery film will eventuate, requiring pressure hosing or harsh chemical removal. Not so with asphalt which is resistant to pooling and mould growth and not slippery when wet!

Using pavers or concrete to provide pathways through a landscaped garden will always be susceptible to lifting and cracking caused by both rain, traffic and root growth underneath. This can result in severe trip hazards and unsightly cracks that require the whole area to be replaced.
Asphalt however is less susceptible to such damage and often cracks require just a minor repair and re-seal without the need to dig-out and relay large areas. Unlike concrete, asphalt does not require channel breaks that can be a haven for weeds, nor does asphalt need pressure spraying to remove mildew and mould growth.
Asphalt provides a smooth and seamless surface that will beautify any garden or landscape with durability and ease, giving your garden spaces a continuous and even backdrop to show off the beauty of your plants and trees.

The benefits of using asphalt versus concrete in landscaping are numerous. Firstly asphalt can be sculpted to suit the contours of the garden area creating interest points and focus areas that are both durable and safe as well as pleasing to the eye. As asphalt is porous garden beds are more likely to flourish as rainwater is more evenly distributed without the continual runoff caused by non-porous concrete.
Of course it is possible to design asphalt with slight cambers that can direct excess water into places needed most such as plantings that require high watering. Concrete is also susceptible to staining from vegetation overgrowth whereas asphalt will retain its beauty enhancing the overall appeal of the landscape surrounds.
