![]() Reduction of material/demolition cost and decreasing the total amount of construction time.Increase roadway lifespan and decrease maintenance intervals.Increase in structural stability by providing for more stable subgrade moisture contents.Non-structural asphalt overlays are mostly used to improve the functionality of a pavement such as improving friction and ride quality, reducing noise, and correcting surface defects. It can be used for either structural or non-structural purposes. ![]() After the road surface has been softened, 12 cm on the surface is scarified by scarifying mechanism. The interlayer thermal bonding technology refers to: Before paving asphalt mixture on road surface, intermittent heating on the underlying layer is done by heaters. Reducing reflective cracking in the overlay by acting as a stress-absorbing membrane interlayer. Asphalt concrete (AC) overlay is a widely used pavement rehabilitation treatment. 2.3.6.4 Interlayer thermal bonding technology for asphalt pavement.Waterproofing of the lower layers, thereby, maintaining higher material strengths.Proven benefits of using SKAPS geotextile in concrete pavement overlays include: Pavement deterioration is caused by shear and tensile stresses induced by traffic loads, changes in pavement temperature, shrink/swell soils, existing cracks, and movements of the underlying pavement structure. Where the pavement is sufficiently strong, a thin overlay of ½to¼ in. As the geotextile is bonded with saturated asphalt cement to existing asphalt, the fabric placement reduces reflective cracking and deterioration that could potentially lead to a roadway failure. Asphalt overlays are required for restoring pavement smoothness and for strengthening existing pavements. The primary function of asphalt overlay paving geotextiles is to act as a stress-relieving membrane between several layers of pavement. Paving fabrics are bonded to the road surface and saturated with bitumen to effectively seal the existing pavement and waterproof the overlay. ![]() SKAPS non-woven needle-punched geotextiles, GC130, and GC140 are utilized as paving fabrics to increase the flexibility of a particular roadway structure.
