Quality Acceptance Standards for Hot Melt Road Coating Spray Two Component Marking Coating (Latest Version)

Spray two-component marking paint is an important material for modern road traffic markings, and its construction quality directly affects road safety and service life. The scientific and standardized acceptance criteria are a key link in ensuring the quality of marking engineering. TOP ROAD Transportation Technology Co., Ltd. has systematically sorted out the following key acceptance points based on national standards and years of practical experience, providing clear basis for engineering acceptance.

1、 Core indicators for appearance quality acceptance

Qualified two-component markings should have clear and neat visual effects. During acceptance, attention should be paid to whether the edges of the markings are straight and sharp, whether the surface is smooth and flat, and whether there are obvious defects such as bubbles, cracks, peeling, etc. The color should be uniform and consistent, meet the design requirements, and have good visual recognition under night conditions. TOP ROAD reminds that environmental control and material ratio during the construction process are the foundation for ensuring appearance quality.

2、 Specification for Acceptance of Dimensional Accuracy

The dimensional accuracy of markings includes width, length, and positional accuracy. The deviation between the actual marking position and the design position should be within the allowable range, the width of the marking line should be uniform and consistent, and the segment length and spacing of the intermittent line should meet the requirements of the specifications. For special markings such as graphics and characters, their shape and size must be consistent with the design drawings.

3、 Key points for performance acceptance in use

Durability is an important performance indicator for two-component marking. During acceptance, the adhesion strength between the marking and the road surface should be checked to ensure that there is no detachment phenomenon; Wear resistance performance needs to meet long-term usage requirements; The reflective performance should ensure night visibility, with evenly distributed glass beads and moderate embedding depth. TOP ROAD recommends simulating different climatic conditions for performance testing during acceptance.

4、 Environmental Protection and Safety Acceptance Requirements

Modern marking engineering also needs to pay attention to environmental and safety indicators. The material should comply with environmental standards and not contain harmful substances; The markings after construction should have anti slip performance to ensure driving safety; Under special weather conditions such as rain and fog, the markings should maintain sufficient recognition.
