The plant where high-density polyethylene pipe is being manufactured needed repairs to its pipe storage area. The repairs became necessary because the stone layer did not shed water and it caused cracks. The cracking of the storage pavement area made it necessary to stabilize the site.
So it became necessary for engineers to look for a way that would be economical and would not require shutting down the operating area of the plant. After testing a number of alternatives, it was decided to use polypropylene fibres for the purpose. It was found out that when being mixed with soil the fibres produce the necessary stability. The way the engineers proposed turned out to be economical and quite successful.

The fibre reinforced polymer bridge deck is a newly-invented arrangement. It is made up of composite materials. They are extremely useful since, because of their composition, they have a wide range of application. Compared with other conventional materials they can solve a much greater number of problems.
One of the advantages of the bridge deck is that it is highly resistant to corrosion and fatigue. The material it is made up of is very easy to transport; it also allows rapid installation using lighter equipment and much less manpower. Holes are easily cut in the deck. They can be closed out to accommodate the same drainage scuppers that are used on conventional decks.

F. Hennebique was born in France, in the family of a farmer. Already in his childhood he became fond of natural sciences and spent his free time on reading books on natural sciences. At the age of 18 he became an apprentice of a builder and at the same time he continued his studies of theoretical technology. At the age of 25 years Hennebique specialized in restoring churches. He travelled all over the country visiting cathedrals and examining their architecture and construction.
As years passed by, he grew interested in railway works, including bridges and viaducts. In 1844 he designed a house for a client and, to prevent damage by fire, combined good-quality steel with concrete in compression. In this way he realized a new idea to put steel rods in the bottom of the slab in order to prevent any damage by fire. That building with its fire resistance guarantee was completed in 1880 and stood until destroyed during the First World War.
From that time on, F. Hennebique concentrated on the development and production of reinforced concrete constructions. One of his reinforced concrete buildings of that time, a single-storey structure in Paris, had a concrete and glass roof.
