Reynold's Roadpacker 235 Special

On the left hand side you see the traditional matter of road construction.	In contrast you can see the treatment with RRP 235 Special and his many advantages:
There must be deep excavations and the material must be transported  and stored.	The top soil is removed next we loosing the surface using for example a discarer. The supervising engineer then determines the mixture and the RRP 235 Special is applied.
Large quantities of barrel, grabble and sand must be brought in - and the ground base has to be compacted again and again – it is troublesome, laborious and expensive.	Directly after the application these layer can be compacted. It is also possible to form several layers with the stored subsoil materials available on side nearby. The asphalt wearing layer can be constructed directly on top of the five to ten centimeter ballast layer.

Let's compare the costs:
We take as base a road class 4 AST 075 with a length of 800 meters and a traffic wide of 8 meters:
For a conventional constructed road 3,800 cubic meter of soil must be excavated 224,000.- Marks
For the same road constructed with RRP the cost is 160,000 DM.
On the traditional side the excavation have to be replaced by about 4,200 cm3 of materials for 212,000 DM

Subsoil treatment with RRP 235 Special  costs 105,000 DM Using the traditional matters to construct the supporting and asphalt layers costs 291,000 DM While with RRP 235 Special these final layers  represent a cost of 198,000 DM The total for the conventional constructed road is 727,000 DM over 50 percent more expensive than the RRP road with 463,000 DM On the conventional side more as 10,000 cubic meter of material have to be removed.  4,500 cubic meter of material need  to be transported on the RRP side.

That saves money, material and mileage.
There is also a considerable saving of time with RRP
We have not compared the minimum requirements of road construction equipment when using RRP.
In developing countries it is sensual to be able to construct roads with relatively simple equipment
The results of this comparison between traditional road construction and RRP are clear:
Responsible managers will accept them and have to include them in their decision making.

In the 50th in American natural physicist professor Reynolds investigated the effects of interchanging ions substances in order to utilize the road construction. Professor Mangold of the technical university of Munster, who is well qualified to give has opinion on RRP 235 Special and his scientific consultants on application techniques explains: “In order to understand the ion exchanging effects of RRP we have to look at the fine structure of earth: in his microcosm we encounter larger and smaller particles of soil as well as water

The single components of soil, the colloids are surrounded by a coating of water,. and fine vessels passed through the colloids as capillaries. This water coating can expand and the soil swell in volumes; or if the water covering shrinks then the soil will crack open and fracture. If you go nearer and observe the colloids more intensively you will have that scenic picture:  on the surface of the colloids we find a layer of mostly electrical negative ions.  Among them there are also ion interchangeable active OH negative ions. The surrounding area between colloids are mainly cationic  - charged positively. The number of positively and negatively charged ions is equal and the electrical condition is balanced. Until the development of RRP we had to try to replace the surplus water in the surrounding area by compression.   This - as we know - is insufficient: when the pressure is released or changes in any way, an accumulation of water is always possible The totally different effect of RRP results from the ion exchanging mechanism  of  sulphonic acid which is the mainly ingredient of RRP. In water the acid separates the proton the H positive ion which join the water molecule to form the H3O positive  ion. When RRP is applied to the soil a dissociation takes place and the interchange of ions occurs. In water the H positive ions are freed and react immediately with the OH negative ion on the coating of the colloid. The new available space on the colloid  cover is now occupied by the electric negative exchange ion of the sulfuric acid. The adherent is waterproof. The colloid does obtain a specifically balance moisture cover which means that the particle are impregnated and cannot shrink or swell anymore. The water in the surrounding areas cannot adhere anymore and runs off like water off a dogsback.
It becomes clear that such effect can be successfully used for drainage. The opposite effect is achieved when RRP treated soil is compacted. The colloids close together so the impregnated layers becomes water resistant.
When you put imposed loads of ballast gravel and sand on to soil treated with RRP it doesn’t sink.
Roads remain firm and they compact still further
For a concrete surfacing resting directly on the subgrade and for medium to heavily trafficked roads the bearing capacity on the surface of the sub-base (frost blanket) or, if no sub-base is provided, on the subgrade, must be:
