Mixing grade bitumen emulsifiers
Slurry seal and microsurfacing
Slurry seal and microsurfacing are used as thin wearing courses to restore the surface roughness of damaged roads. They can also be used as a new course on grave-emulsion or as surface dressings. They consist of aggregates with a very specific particle size, bitumen emulsion, water, cement, and, in some cases, a breaking-control additive. This technique is one of the most complex techniques in the paving industry. Our experts will help you find the right formulation among all the components.
The grave-emulsion is a coating technique wherein coarse aggregates are coated to a greater or lesser degree in a binder-rich mastic. In construction, the grave-emulsion is used as a base course and a binder course for low to medium traffic. It can be laid using a finisher or a grader. In this case, the aggregate emulsion can be used for reprofiling, reshaping and widening.
Storable cold mix
This application is a cold mix whiach can be stored for several weeks, its production is similar to cold mixes but the formulation proportions are different. Storable open graded cold mix is used in maintenance to patch up potholes and similar localized damages from weathering and traffic.
