Viscosity Grade (VG)

Home Viscosity Grade (VG)

 粘度等级 (VG)

 

根据粘度分类，VG沥青适用于包括热拌沥青 (HMA) 和温拌沥青 (WMA) 在内的沥青混合料。它在不同气候和交通条件下能确保最佳的性能和耐久性。

 

  • VG 10: 适用于低流量道路和轻型应用，提供良好的可加工性和耐用性。
  • VG 20: 适用于中等流量道路和通用沥青混合料，粘度与性能平衡。
  • VG 30:为高流量道路和重型应用设计，具备优异的抗变形和抗裂性。

 

应用领域

  • 道路建设：广泛用于道路、高速公路和人行道的建设中作为粘结剂。
  • 沥青混合料：常用于热拌沥青 (HMA) 的生产，用于铺设道路、停车场和车道。
  • 防水：用于制造防水膜，如屋顶和地下室的沥青防水层。
  • 工业应用：用于制造沥青基涂料、密封剂、粘合剂和油漆。
  • 道路维护：在道路维护和修复项目中用于修补、裂缝密封和坑洞修复。
