CARPET.Compose - Entwicklung eines neuartigen, polymeren Straßenbelags

该研究项目的目的是进一步开发一种新型的，预制的，可滚动的，无沥青的道路面层。最初，顶部被设计为基于化学反应性水泥聚合物分散体的膜的三层层压件。出于技术原因，将该三层顶层改为10 mm厚的单层，其中骨料嵌入反应性水泥聚合物分散体中。预制顶面的开发应确保其可以展开，固定在地面上，并在安装后不久即可使用。此外，面层应具有持久的抓地力，这是通过将矿物混合物嵌入聚合物水泥分散体中来实现的。在加入水进行水合和硬化反应之后，聚合物应该溶解。因此，硬化水泥应为矿物骨料提供强基质，其机械性能和耐久性比沥青质沥青更好。水泥熟料的连续水化/结晶确保了自修复效果，因为松散的矿物将再次结合到基质上。最后，矿物混合物应提供地毯面层，具有足够的排水和噪音管理，以避免由于道路上的水过量而产生的滑水和噪音排放。

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.
