Viscoelasticity – The rheological characteristic of a bituminous binder represented by both viscous and elastic behaviour, i.e. behaviour which is like that of each a solid and a liquid, in response to an applied stress. Primer binder – A material which is more viscous than a primer that's used to act each as a primer and binder and used in primer sealing. Polyethylene – A plastomeric polymer used in the modification of bitumen. Kinematic viscosity – The ratio of dynamic viscosity to density of a material. Ethylene vinyl acetate – A plastomeric polymer used in the modification of bitumen.

Traditional tiles are produced from terracotta clay, but there are additionally ceramic tiles roofs , as well as concrete tile roofs. All consist of particular person tiles put in in overlapping layers over the roof surface, and all have roughly the same degree of energy and durability. They require a sturdy roofing framing adequate to carry the burden and must be put in by skilled professionals.

Selenizza is principally used as an additive within the road building sector. It is blended with traditional asphalt to enhance each the viscoelastic properties and the resistance to ageing. It could also be blended with the recent asphalt in tanks, but its granular type allows it to be fed within the mixer or in the recycling ring of regular asphalt plants. Other typical applications include the production of mastic asphalts for sidewalks, bridges, automotive-parks and urban roads as well as drilling fluid additives for the oil and gasoline trade. Selenizza is available in powder or in granular materials of varied particle sizes and is packaged in sacks or in thermal fusible polyethylene baggage.
