In the construction of modern transportation infrastructure, the safety and durability of roads are very important. Composite drainage network is a commonly used material in roads, so can it increase the life of roads?
1. Basic characteristics of composite drainage network
The composite drainage net is composed of plastic net with three-dimensional structure bonded with water-permeable geotextile on both sides. Therefore, its drainage performance is very good, and it can quickly export groundwater or rainwater, which can reduce the problem of water accumulation in the road base. It also has high tensile strength, corrosion resistance, acid and alkali resistance,
Convenient construction and other advantages.
2. The impact of road water accumulation on road life
Water accumulation on roads is one of the main causes of road damage. When the road base layer accumulates water for a long time, it will lead to soil softening and bearing capacity decrease, which will lead to pavement collapse, cracks and other diseases. These diseases not only reduce the capacity of roads, but also increase maintenance costs and shorten roadways
The service life of the road. Therefore, solving the problem of road water accumulation can prolong road life.
3. The role of composite drainage network in prolonging road life
1、Rapid drainage: The three-dimensional structure of the composite drainage network can quickly export groundwater or rainwater, reduce the water accumulation time of the road base, and reduce the risk of soil softening and bearing capacity reduction.
2、Enhanced base stability: The high tensile strength of the composite drainage network can enhance the stability of the road base layer and prevent deformation and cracks of the base layer caused by vehicle load or temperature changes.
3、Isolation and protection: The double-sided geotextile of the composite drainage network can play an isolation and protection role, prevent the fine material of the base layer from entering the drainage channel, and keep the drainage system unimpeded. It can also prevent the erosion of the base layer by external harmful substances and prolong the service life of the road.
4、Construction convenience: The composite drainage network is convenient to construct, which can shorten the construction period and reduce the construction cost. It can improve the efficiency of road construction and reduce traffic interference.
From the above, it can be seen that the use of composite drainage netting can extend road life. It has the advantages of rapid drainage, enhancing the stability of the base layer, isolating and protecting the base layer, and convenient construction, and can provide reliable drainage solutions for road projects.
