Road Construction
Filling in road construction and geotechnical structures :
Leca is applied in road construction and tunnelling for filling of non-pressure spaces. One of the important advantages Of Leca applications is the control of the plastic settlements in these places. Also, since the weight of filling material has an important act in amount of vertical and horizontal pressure applied on foundations, retain walls and piles, use of light and durable Leca aggregate in these fields is very valuable.
In many cases, e.g. children playground, gravel can be replaced with Leca aggregates. Important particular of Leca is round shape and non-scraper or hard surfaces, that is causes injuries.
