<p>The invention relates to a constructive procedure for pervious stripes located between embankment reinforcements and the highway system, which enable passage and filtration of water and have absorption wells. The constructive procedure involves the following steps: 1) excavating a stripe in the area where the carpet joins the embankment reinforcements and in certain cases, preparing the absorption wells; 2) compacting the soil manually or mechanically; 3) placing an impermeable membrane between the carpet and the pervious stripe; 4) placing an aggregates filling excluding dust or talc-type particles; 5) casting a pervious concrete flagstone comprising aggregates containing no fine particles. The top pervious concrete strip enables passage towards the second layer of filling and the absorption wells which are distributed under said layer. The impervious membrane prevents the passage of water to the base of the carpet.</p> |
