Tack/bond-coating machines

Quality and Economy - from professionals for professionals.

In close collaboration with our customer we developed various types of Tack/Bond-Coating Machines for optimizing the bond between the asphalt courses – as well as of Joint-Spraying Machines to improve the sealing of its joints and flanks.

The schäfer-technic BSM Tack/Bond-Coating Machines transport, warm-up and spray standard bituminous binders of non hazardous classification.

Our Tack/Bond-Coating Machines meet all German corresponding regulations. Due to the requirements at common construction size there are available capacities of the binder tank of up to 12 000 liters and a spray-bar width of appr. 4,6 m.

Exactly keeping the required spraying rate of bituminous emulsion is the key for a high quality cohesion between the asphalt courses and for long durability of the road structure.

Our Spraying technology exactly controls the flow bituminous binder during the entire spraying application.

Layer composite

Important precondition for long lasting road surfaces is a proper cohesion between each layer.

A complete and durable cohesion between the layers assures that the package of road courses will stand the permanent load everlasting. The layer composite results from cohesion, adhesion and mesh between the courses.

Centre Joint

Centre joints result from applying two hot-mix courses aside each other “hot to cold” – no matter whether length – or crosswise. Hot bitumen sprayed onto the joint of the “cold” hot-mix course will create a perfect joint-sealing to the “hot” new hot-mix course to be applied afterwards.

Edge sealing

Sealing of the flanks of the asphalt road. To avoid the water penetrating into / between the asphalt courses they get sealed by spraying hot asphalt – up to 4 kg/m.
