Roads are essential to infrastructure all around the world, yet a lot of people don’t know the hard work that goes into making them. It takes a lot of experience, patience and a keen understanding to get the job done right, and getting it right the first time is essential.
Here at AEFaulks, we’re specialists in plant hire in Nottingham, but we also know one or two things about compaction, which is why we’ve put together a few tips to help you, making the job as stress-free as possible.
The biggest mistakes when it comes to a job involving compaction are the simplest ones, mistakes made by even the most experienced road-builder. The most common of these mistakes is over-compaction and under-compaction. Over-compaction occurs when the operator makes too many passes in one direction with their equipment which can greatly reduce soil density.
On the flip side, under-compaction comes as a result of too little passes by the operator, which leaves the soil soft and unable to achieve the cohesion required to achieve the right amount of soil density.
An incorrect lift can also mean added time and energy to a job, so it’s paramount that you get the right amount of lift or depth of the soil. When it comes to filling a trench, you need to ensure you place the right amount of dirt and achieve the right amount of compaction force to the area.
Remember, as the soil becomes compacted, it returns more energy to the machine due to the impact travelling less, resulting in it coming higher off the ground. An incorrect lift, such as one with too much dirt and too much depth will create a loose layer of dirt on a surface, which will result in under-compaction.
Consider the moisture of the soil you’re working with before you start compacting. When it comes to soil moisture, there’s a happy medium – too little will result in poor compaction, but too much will weaken stability. The simplest way to know what you’re working with is a simple hand test: grab a handful of soil and squeeze it before releasing your hand and letting the soil drop. The ideal soil will allow for you to mould it in your hands when squeezed but will break up into pieces when you drop it.
