However By changing the characteristics of normal bitumen with the addition of a polymer, either they are of elastomeric nature or elastomeric. Meanwhile 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.
Typical Viscosity of Binder overlooking temperature
- 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 prime and if appropriate besprinkle with quartz sand. Also Whereupon a spray elastomer coating is spray on, an adhesive primer use is an epoxy resin. Also A emulsion or a emulsion is apply to the plastic granules.
Process for the preparation of a water-impervious surface coating
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, base 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 apply to a base sheet material and also 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
A primer layer (5) is apply to a base sheet material (1) and while the primer layer (5). Also it is still wet a layer of a barrier material (6) of a consistency composition and thickness is applied to the bitumen bitumen bitumen
