Polymer Grade Bitumen
Pavements designed and constructed for heavy duty traffic and extreme weather conditions require specially designed engineered Polymer Bitumen Grades. By changing the characteristics of normal bitumen with the addition of a polymer, either they are of elastomeric nature or elastomeric, we succeed to obtain bitumen that allow the mixture to be more cohesive, with much more strength and significant higher resistance to parameters like fatigue and permanent deformations for road pavements.
Polymer Modified Bitumen (PMB)’s qualities Greater Rigidity Better resistance to permanent deformation Higher Resistance to spreading cracks Greater water resistance Much higher durability Method for producing a sealing for roadways.
In a method for producing a sealing for roadways, for example on bridges for the subsequent application of a base course, top course or wearing course of a road structure, the roadway is primed and if appropriate besprinkled with quartz sand, whereupon a sprayed elastomer coating is sprayed on, an adhesive primer used is an epoxy resin. A emulsion or a emulsion is applied to the plastic granules.
Process for the preparation of a water-impervious surface coating : Polymer Grade Bitumen
A process for the preparation of a water-impervious surface coating on a substrate comprising applying to the substrate a layer of an aqueous emulsion containing, based on dry matter, 5-55% by weight of an acrylic prepolymer, 1-15% by weight of an air-drying alkyd resin, 40-80% by weight of method of forming coatings, coatings so formed and articles coated thereby a method of coating articles, a coating and a coated article wherein a primer layer is applied to a base sheet material and while the primer layer is still wet a layer of a barrier material of a consistency, composition and thickness is applied to the bitumen bitumen bitumen.
