道路养护

What is Road Maintenance and why it’s necessary?

道路对于一个国家的发展和发展至关重要,它们是连接生产中心和市场的重要纽带。修新路要花钱,但如果不好好保养,路很快就会变质。如果不采取任何措施,设计寿命为几十年的道路可能需要在几年后进行更换或大修工作。因此,有必要制定长期的维修资金计划。

预防性养护是为了改善或延长路面的使用寿命。它是一种表面处理和操作的策略,旨在延缓逐渐发生的故障,并减少日常维护和维修活动的需要。

在路面出现缺陷(如摩擦损失、中度到严重车辙或大面积开裂)后进行纠正性维护。也可称为“反应性”维护。

Ziggurat Oil Company tries to provide all solutions for Road Maintenance needs. Bitumen emulsions such as CSS-1, CSS-1h, CRS-1, CRS-2, CMS-2, SS-1h and Bitumen Cutbacks. also the rubberized binder that we produce are highly recommended for maintenance usage.

Types of Road Maintenance Treatments

Crack repair /sealing

裂缝修复/密封是一种局部处理方法,用于防止水和碎屑进入裂缝,这可能包括清理整个裂缝的路线,并创建储液罐以容纳密封剂。它只有效几年,必须重复。然而,这种处理方法对于延长路面使用寿命是非常有效的。包括以下三种裂纹修复方法(密封、填充、全深度裂纹修复):

Clean and seal

用于所有类型的裂缝,包括使用热空气枪或压缩空气吹出裂缝中的碎屑,然后填充密封剂。我们用Ziggurat Oil 生产的橡胶粉改性沥青在清洁和密封方面非常有效。

Saw and seal

包括使用路面锯沿新铺设的路面每隔一定的间隔创建横向接缝,然后用密封剂填充。

Rout and seal

用于横向和纵向裂缝。包括使用路面锯或刨削机在现有裂缝上形成一个储液罐,然后用密封剂填充。

Crack filling

Differs from crack sealing mainly in the preparation given to the crack prior to treatment and the type of sealant used. Crack filling is most often reserved for more worn pavements with wider, more random cracking. Asphalt emulsion can be used as a crack filler. Hear in Ziggurat Oil we supply Asphalt Emulsions such as CSS-1, CSS-1h and SS-1h that use for crack filling.

Full-depth crack repair

局部处理方法,用于修复因密封而变质而无法受益的裂缝。二次开裂需要重新建立底层基础材料。

Fog seal

使用稀释的乳液(通常以1:1的比例)来丰富路面表面,延缓剥落和氧化。被认为是临时治疗。雾封可采用缓凝沥青乳液。

Seal coat

用于表面防水,密封小裂缝,减少路面氧化,提高摩擦。

Double chip seal

涂抹两层单层封层。第二层紧跟在第一层之后。这种处理可防水表面,密封小裂缝,减少路面氧化,并改善摩擦

Slurry seal

细骨料、沥青乳液、水和矿物填料的混合物,主要问题是现有表面的过度氧化和硬化。泥浆密封用于延缓表面剥落、密封微小裂纹和改善表面摩擦。

Microsurfacing

通常被称为聚合物改性稀浆封层;然而,主要区别在于,微表面处理的固化过程是一个化学控制的过程,而不是泥浆封层和芯片封层使用的热过程。也可用于填补车辙。

Thin hot-mix overlays

包括密实、开放和间隙级配混合料,可提高行驶质量,减少路面氧化,提供表面排水和摩擦,并纠正表面不规则。

Pothole patching

包括使用冷热沥青混合料、喷射方法以及泥浆和微表面材料,以修复损坏并提高行驶质量。
