Geocomposite drainage for drainage purposes on transport infrastructure objects
Geocomposite drainage for drainage purposes on transport infrastructure objects
Couldn't load pickup availability
In addition to conventional systems, such as drainage layers made of unconsolidated, permeable materials, geocomposites are increasingly encountered on construction sites. This methodology describes in detail the design, sizing and application of geocomposite drainage for drainage purposes on transport infrastructure objects.
The aim of the methodology is:
- describe geocomposite drainages, their composition and the materials used,
- specify the design, dimensioning and installation method of geocomposite drainage,
- present the possibilities of applying geocomposite drainage on transport infrastructure objects,
- provide details, sample sheets and concrete examples of execution.
This methodology was developed with the state support of the Technology Agency of the Czech Republic as part of the Center of Competence program, CESTI project (TE01020168: Center for efficient and sustainable transport infrastructure, working group WP1: Ground communication – intelligent and durable technological solutions with high technical efficiency).
