A road underdrainage system is a set of facilities designed to capture, convey and evacuate water that accumulates under or next to the layers that make up a pavement structure, in order to avoid problems such as soil saturation, excessive moisture, erosion or hydrostatic pressure on these layers.<\/p>\n

 <\/p>\n

When an underdrainage system is not implemented in the design of a pavement, saturation of the granular layers, increased pore pressure in the subgrade soil, loss of material due to erosion, among many others, occur. There is a severity factor proposed by Cedergren, which measures the relative damage of pavement performance between dry and wet conditions. For a pavement section with a moderate severity factor of 10, if 10% of the time is saturated, the service life can be reduced by half:<\/p>\n

He transverse underdrainage <\/strong>is in charge of capturing upward water flows and conveying them to the longitudinal underdrainage system. It also prevents the access of subsurface water to the layers of the pavement structure.<\/p>\n

Implement a underdrainage system on a road<\/strong> provides numerous benefits that improve both the durability and safety of the road. The most representative ones are listed below:<\/p>\n

    \n
  1. Improved soil stability:<\/strong><\/li>\n<\/ol>\n

    \u00a0<\/strong>Controls the water table and excess groundwater that can cause differential settlement or landslides, especially in sloping or unstable terrain. Underdrain stabilizes the ground and prevents structural failure.<\/p>\n

      \n
    1. Prolongation of pavement life: <\/strong><\/li>\n<\/ol>\n

      Water is one of the factors that deteriorate roads the most. If it accumulates in the subgrade, it weakens the granular layers of the pavement, causing deformations, cracks and potholes. A good subgrade system prevents this damage by keeping the supporting soil dry.<\/p>\n

        \n
      1. Reduced maintenance costs:<\/strong><\/li>\n<\/ol>\n

        By avoiding severe structural damage to the pavement, the frequency and magnitude of necessary repairs is reduced, resulting in significant long-term savings.<\/p>\n

          \n
        1. Improves the functioning of surface drainage systems:<\/strong><\/li>\n<\/ol>\n
