The degree of temperature reduction in the concrete slab was. Clean the pavement to remove any dirt, gravel, or trash that may have appeared since the preliminary cleaning. Close the work area to traffic by erecting barricades, tape, or other control devices. Reduction of material/demolition cost and decreasing the total amount of construction time. The AC overlay considerably reduced the uniform temperature variation and temperature gradient in the underlying concrete slab. When the day arrives to install your asphalt overlay, the contractor will see that the following steps are completed.Increase roadway lifespan and decrease maintenance intervals.Increase in structural stability by providing for more stable subgrade moisture contents.Reducing reflective cracking in the overlay by acting as a stress-absorbing membrane interlayer.Waterproofing of the lower layers, thereby, maintaining higher material strengths.Proven benefits of using SKAPS geotextile in concrete pavement overlays include: Where the pavement is sufficiently strong, a thin overlay of ½to¼ in. 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. Asphalt overlays are required for restoring pavement smoothness and for strengthening existing pavements. 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. 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.
