What issues should be noted before the construction of road grouting machine

Road crack filling machine is one of the common ways to solve cracks. Grouting is a reasonable protective maintenance measure, and the purpose of grouting is waterproofing. Below, the editor will explain the issues that need to be paid attention to before the construction of the road grouting machine:

1. Construction temperature of road grouting machine: The construction temperature is one of the reasons why the sealant falls off. When the road surface is wet and the temperature is less than 4 ℃, it will reduce the adhesion of the sealant, making it very easy to fall off. The overall temperature of the road surface is relatively low. After the sealant is filled, the temperature drops rapidly, and the sealant shrinks significantly. The temperature stress between the sealant and the groove wall is high, which will reduce the adhesion between the sealant and the road surface.

2. Humidity in crack environment: When filling cracks, the road surface should be dry and rough. If it is wet and cold, it will reduce the adhesion between the sealant and the road surface, causing some of the sealant to fall off.

3. Keep clean: Before filling the cracks, use an air compressor to remove dust, dirt, and loose objects from the cracks after opening, and maintain the cleanliness of the cracks.

The above three points are the precautions that need to be taken before the construction of road grouting machines introduced by the editor. I believe that after reading them, everyone has a certain understanding. If you want to consult more related information, you can follow our company website.
