VG40沥青用于交通繁忙的高压区域,例如十字路口,收费站附近和卡车停车场。由于该沥青的高粘度,它更适合于提高抗刮擦性以及与高温和高交通负荷相关的其他问题。

VG 40 OR 40/50? VG 40或40/50?

VG 40沥青和渗透级沥青40/50看起来完全一样,它们的物理性质,粘度范围和性能完全不同。VG 40沥青已针对高温下的道路施工进行了优化。由于该沥青的粘胶性能是在三种不同温度(25、60和135°C)下测量的,因此与笔级沥青40/50相比,它提供了更轻松的操作和维护。要将VG 40沥青与渗透等级40/50区别开来,有必要检查所购买沥青的沥青测试结果。测试结果(VG 40的绝对粘度应为3200泊,渗透值应在40到60之间)。我们不仅可以控制VG 40的测试结果,还可以在装载前测量沥青桶的性能。 与SGS检验员合作,我们对VG 40沥青进行了非常仔细的采样和测试,并将结果发送给我们的客户。

Usage: Bitumen VG-40 is used in highly stressed areas such as: Intersections, Air ports, truck parking lots, near toll booths and roads with heavy traffic loads in higher temperatures. Because of higher viscosity it also can be used instead of 30/40 bitumen penetration grade.
