Marking of hot-melt road coatings to reduce costs and increase efficiency – coating density

Industry standard 1.8g/㏄ -2.3g/㏄ Coating dosage=Coating density x Volume of marking (marking area x marking thickness) Marking thickness 2mm Calculated density of 1.8g/cm ³ Coating dosage of 1 square meter 1 ㎡ Marking dosage (weight)=Volume * Density=2mm * 1 ㎡ * 1.8g/cm ³=3.6 kg/㎡ Coating dosage of 1 square meter with a density of 2.3g/cm ³
The amount of paint used for a 1 ㎡ marking line (weight)=volume * density=2mm * 1 ㎡ * 2.3g/cm ³=4.6 kg/㎡ or more. Compared to a paint with a density of 1.8g/cm ³ and a marking thickness of 2mm, the amount of paint used for a 1 ㎡ marking line with a density of 2.3g/cm ³ is 1 kg/square meter more.

Of course, the actual situation needs to consider the roughness of the road surface. Depending on the roughness, a coefficient can be added to the thickness appropriately. For example, the coefficient can be ignored for smooth cement pavement, epoxy flooring, etc. If the thickness of the marking on the rough asphalt pavement increases to 3mm, the amount of marking (weight) for 1 ㎡=volume * density=3mm * 1 ㎡ * 1.8g/cm ³=5.4 kg/㎡, regardless of the pavement, the difference in amount between the two is certain.

Conclusion: A 10000 square meter marking can save you 10 tons of paint compared to low-density coatings. The cost of relatively low-density coatings is definitely higher than that of high-density coatings, which means that if you buy a particularly cheap coating, you need to consider whether your construction cost can compensate for the price difference caused by the amount of coating used. The density of coatings from different manufacturers must be different, whether you believe it or not, there is an objective existence of coatings that are more material efficient and square.
