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.

该研究项目持续的目的是进一步开发出一种新颖的，预制的，可滚动的，无沥青的道路上衣。最初，该浇头设计为基于化学反应性水泥聚合物分散剂的膜的三层层压板。由于技术原因，这种三层浇头被更改为一个10毫米厚的层，其中聚集体嵌入了反应性水泥聚合物分散体中。预制的浇头应以一种可以展开，固定在地面上并准备在安装后不久就可以使用的方式开发。此外，浇头应具有持久的握力，这是通过将矿物混合物嵌入到水泥中的聚合物分散剂中来完成的。加水以进行水合和硬化反应后，聚合物应溶解。硬化的水泥应与沥青沥青相比，具有更大的机械性能和耐用性的矿物聚集体的强基质。持续的水合/结晶o水泥熟料可以确保自我处理效果，因为松动的矿物将再次与基质结合。最后，矿物混合物应为地毯上衣提供足够的排水和噪音管理，以避免由于道路上过多的水而导致的水植物和噪音排放。
