The aim of this research project continuation is to further develop a novel, prefabricated, rollable, bitumen-free topping for roads. Originally the topping was designed as a three layer laminate based on films of a chemical reactive cement-in-polymer dispersion. For technical reasons this three-layer topping was changed to a single 10 mm thick layer, in which aggregates are embedded in the reactive cement-in-polymer dispersion. The prefabricated topping should be developed in such a way that it can be unrolled, fixed to the ground and be ready to use shortly after mounting. Furthermore, the topping should have a long lasting grip which is accomplished by embedding a mineral mixture in the cement-in-polymer dispersion. After adding water for the hydration and hardening reaction, the polymer should dissolve. The hardened cement should provide thus a strong matrix for the mineral aggregates with greater mechanical properties and durability than the bituminous asphalts. The continous hydration/crystallization o the cement clinker secures a selfhealing effect, since loosened minerals will be bound again to the matrix. Finally, the mineral mixture should provide the carpet topping with adequate water drainage and noise management to avoid aquaplaning and noise emission due to water excess on the road.

本次研究项目继续的目的是进一步开发一种新型的、预制的、可卷曲的、无沥青的道路面层。最初，顶层被设计为基于化学活性聚合物水泥分散体膜的三层层压板。由于技术原因，这种三层顶层改为一个10毫米厚的单层，其中骨料嵌入活性聚合物水泥分散体中。预制顶盖的开发方式应使其可以展开，固定在地面上，并在安装后不久即可使用。此外，顶部应该具有持久的抓地力，这是通过在聚合物水泥分散体中嵌入矿物混合物来实现的。在加入水进行水合和硬化反应后，聚合物应该溶解。因此，硬化的水泥应该为矿物集料提供一个坚固的基质，具有比沥青沥青更好的机械性能和耐久性。水泥熟料的持续水化/结晶确保了自愈效果，因为松散的矿物质将再次结合到基质上。最后，矿物混合物应为地毯面层提供足够的排水和噪音管理，以避免因路面水分过多而导致的滑水和噪音排放。
