Methods of screeding
Different methods of screeding are used, depending on the size and scope of the project. Traditionally liquid screed is manually spread across the surface before a screed board or straightedge is used to level and smooth it. For larger areas, power screeding machines are used which are much quicker and achieve consistent results.
After the screed is applied, it needs time to cure and harden before surface finishes can be applied. The curing time can vary depending on the type of screed used, the environmental conditions and other project specific factors. Once properly cured, additional finishes or floor coverings can be applied over the top to complete the process.
In asphalt placement an asphalt paver is used to spread and compact hot mix asphalt (HMA) onto the roadway. As the paver machine moves forward, the asphalt is continually distributed across the prepared roadbed. Located on the rear of the paver is a screed, which is an adjustable attachment consisting of metal plates that extend the full width of the paver. The screed is used to level the hot asphalt and achieve the desired depth of the road or pavement. Sometimes tamper bars are used with the screed, which help to compact the asphalt and eliminate any voids.
The benefit of using the screed is that it produces a smooth, uniform finish whilst it passes across the freshly laid asphalt. Our operators are fully trained and experienced in the operation of the screed, able to adjust its height, angle and other constraints to achieve consistent results and eliminate irregularities. This results in a well compacted footpath or road, which improves the ride quality, durability and safety for road users.
