Colored anti-skid pavement is made by sprinkling ceramic particles on the road surface and laying them in a certain amount. It makes traditional road surfaces pleasing to the eye and has good anti slip effect through colored construction. How to solve the problem of wet road surface during the construction process of colored ceramic particles?
On the one hand, colored anti-skid pavement can beautify the road environment, and on the other hand, it can make transportation more convenient, so it is increasingly being adopted. Therefore, ceramic particle adhesive is widely used. But in some wet and slippery areas, construction cannot be carried out according to the previous methods, and unfavorable water temperatures must be considered during construction.
When ceramic particle adhesive is used for some high-temperature and moderately humid road sections, due to the impermeability of the surface layer, the water accumulated in the roadbed and base layer due to temperature and humidity gradients cannot be removed through the surface layer. If the water stability of the grassroots is poor, its strength and stiffness will decrease, leading to damage to the road surface. Generally, materials with good water stability should be selected as the base for colored anti-skid pavement, especially in the middle and wet sections. In addition, in wet and excessively wet sections with poor hydrogeological conditions of the roadbed, in addition to strengthening roadbed drainage, technical measures such as stabilizing the upper layer of roadbed soil with low-dose lime or adding granular cushion layer can also be used to increase roadbed water temperature.
In frozen soil areas during the deep freezing season, when the roadbed soil is prone to freezing, the hazards of frost heave and frost heave should be considered. The determination of the total thickness of the road surface should not only meet the requirements of mechanical strength, but also meet the requirements of the thickness of the antifreeze layer, to avoid the occurrence of thick ice accumulation zones on the inner side of the roadbed, which may cause uneven frost heave and cracking of the road surface.
The above is the moisture problem of colored ceramic particle anti-skid pavement, which can be used as a reference during construction. It can effectively reduce the noise at the contact point between the tire and the ground, and also generate diffuse reflection to transmit the engine to the road surface, consuming some sound.
