Removing a large area of cracked and weed-grown pavement to be replaced with new concrete is a large job. But, the right types of heavy construction equipment will make the job easier with large construction equipment doing all your heavy work. These three pieces of used heavy construction equipment for sale make a pavement replacement project easier and will help you to work smarter instead of harder.

Jackhammer

When you have a large area of old broken concrete that is beyond repair, you need to break it up and remove it from the ground to make space to pour new concrete. A manual jackhammer can be tiring to your entire body and cause problems with blood circulation in your fingers. So, why not use an excavator with a hydraulic jackhammer attachment instead? 

Because a manual jackhammer is also loud, emitting 100 decibels of sound up to 100 meters away, a jackhammer attachment on an excavator can benefit your team. You or a member of your construction team can run a hydraulic jackhammer attachment from the cab of the excavator so you are not right next to the jackhammer's point bit. This keeps you at a distance from the loud sound, but you and others working nearby will still need to wear ear protection during the pavement demolition.

The hydraulic jackhammer has enough power from its hydraulic system that it does not need the force of gravity to help break up hard surfaces, such as concrete. You can use this jackhammer attachment to break apart walls and even ceilings above you at a rated speed of 2200r/min.

Front End Loader

As soon as all the pavement has been broken up into manageable pieces, the front end loader can come in and scoop up all the cement debris to clear the area. A high-capacity front end loader can lift up to 5000 lbs, so even the largest chunks of broken pavement can be easily cleared away and dumped into the back of the dump truck on site.

As the front loader's bucket scoops the area clear, the ground will be scraped even to create a smooth surface that is ready for the pouring of new concrete.

Concrete Truck

After the concrete forms have been set and you have pounded flat the sub base, then you can prepare the concrete truck for supplying the work site with wet concrete. Combine the concrete mixture no more than 90 minutes before you will pour it, otherwise it will begin to harden inside the rotating drum on the concrete truck. 

If there is a delay in delivering the concrete, the concrete will set up and harden inside the drum. The only way to remove hardened concrete from inside a concrete truck tank is by hammering it, usually with a jackhammer.

Most cement is a mixture of cement powder, sand or gravel, and water that is combined together inside the tank. You will need to adjust the mixture of cement depending on the climate where the cement will end up. This is to prevent any cement scaling or spalling in colder climates where the weather fluctuates between freezing and thawing. If you have ever noticed a cement surface that has begun to flake and chip away, this is because the wrong mixture of cement was used for the climate.

After you pour the cement, smooth it out to remove any air pockets and lumps, then finish it, the cement will begin to cure. After curing for up to 48 hours, you can remove the concrete forms.

These three pieces of heavy construction equipment, along with the right know-how, will help make your concrete project much easier.
