Lucobit1210A是乙烯共聚物和特殊沥青的混合物。所得配方为浓缩物或“母料”。Lucobit 1210A由热塑性聚烯烃组成。在沥青中添加lucobit可增加沥青的粘度并扩大塑性范围。尽管Lucobit的fraas断裂点的最小值与未改性标准沥青一样低,但环软化点和球软化点会显著增加,这取决于添加的Lucobit的比例。渗透值相应地下降。然而,根据DIN EN 12591确定的延展性降低,在低温下确定的所谓延展性值通常比不添加Lucobit的标准沥青更有利。与其他标准粘合剂Lucobit 1210A相比,在提高抗变形性能方面具有显著优势。高温下的车辙形成试验表明,用热塑性塑料对沥青进行改性或通过添加lucobit改变沥青的黏结剂粘度时,沥青能承受2-3倍的荷载。这不会损害Lucobit 1210A的低温性能,而是改善它。即使是相对少量的Lucobit 1210A在沥青混合料中的应用也能提高:抗机械应力,特别是抗变形和磨损稳定性/刚度,并降低热和负载时的流动趋势低温柔性老化行为应用实例:S-耐磨层对ZTV沥青-STB浇注的ASP停车,也可在斜坡表面(坡道)铺设沥青砂胶专用沥青表面,例如多孔沥青薄沥青磨耗层(热铺) Lucobit 1210 A is a mixture of ethylene copolymers and special bitumen. The resulting formulation is a concentrate or "masterbatch". Lucobit 1210A consists of thermoplastic polyolefins. Addition of Lucobit to bitumen increases its viscosity and broadens the range of plasticity. Although the minimum value of the Fraass breaking point of Lucobit is as low as for unmodified standard bitumen, the ring and ball softening point increases considerably, depending on the proportion of Lucobit that was added. Penetration values decline accordingly. Ductility determined according to DIN EN 12591 decreases, however, the values ascertained for the so-called ductility at low temperatures are usually more favourable than those for standard bitumen without addition of Lucobit. Compared with other standard binder Lucobit 1210A displays significant advantages in improving resistance to deformation. Rut formation tests at high temperatures demonstrated that asphalt can bear a two- to three-fold load when modifying it with thermoplastics or altering binder viscosity by adding Lucobit. This does not impair the low-temperature performance of Lucobit 1210A, but rather improves it. Applications Even relatively small amounts of Lucobit 1210A in asphalt mixtures improve: resistance to mechanical stress, in particular deformation and wear stability / rigidity and reduce the tendency to flow when hot and under load low temperature flexibility ageing behaviour Examples for application: s-wearing courses to ZTV-Asphalt - StB poured asphalt, also on sloping surfaces (ramps) stone mastic asphalt special asphalt surfaces, e.g. porous asphalt thin bituminous wearing courses (hot laying) |
