INAUGURATION WITH STRETCH STABILIZATION TECHNOLOGIES ROADS

TComparative experimental bouquet stabilizing products in the Constancy Paysandú.

On 27 September the official opening of the section was performed in which Bitafal group He participated applying technology soil stabilization with Portland cement as reported in the Bulletin # 83 Making Roads of April.

En el mismo, 6 diferentes productos estabilizantes de suelos van a ser evaluados en su desempeño en el tiempo respecto a un par de tramos testigo sin aplicación de ningún producto. La Facultad de Ingeniería está haciendo una evaluación mensual del tramo para ver su evolución.

The inauguration was attended by representatives of OPP, the Mayor of Paysandu, the Director of Works of the Government of Paysandu (IDP), representatives of the Faculty of Engineering and applied products. The Telégrafo_28 / 09 / 2017_VER - for the same conditions of application of the products with the IDP, the commitment of all suppliers and adverse weather conditions that have plagued the section (over 650 mm of rain) highlighted LINK –

Assessment being conducted by the Faculty consists of a measurement by laser Profilograph IRI, counting potholes and regularity of the transverse profile.

The IDP will intervene only in sections witnesses until one of the applied products fail more than acceptable, at what will be the end of their useful life. At the end of this experiment you will have a comparison between durability of each type of stabilizer along with its estimated cost and about not implement anything.

Hopefully excellent performance of cement stabilized as road engineering has proven worldwide for decades and thankfully is being applied in our country regularly.

We will keep you informed of developments thereof.

EFFECTS OF STABILIZED RESTRICTION ON LOSS OF FINES BY PUMPING

31 July 2017
in: Rural Roads,Portland cement,Stabilization,News

Granular basis of any type whatsoever in quality, texture or homogeneity suffer unavoidable variations in the presence of water and is the big problem with road engineering if that happens.

For this is that it gives great importance to the drainage systems in the design of routes, waterproofing the foundations built with asphaltic materials in most of the time and then expected during routine maintenance look that water does not Enter the bases.

We know that there is not a virgin granular material that is not affected by water, hinchándolo in some cases or acting as a lubricant when traffic acts, pumping it from its original location causing potholes.

Stabilizing Portland cement solves the problem of pumping fine and 100% mitigates generating bumps or wells.

Vials know the virtues of Portland cement as a major stabilizer of granular materials for over 50 years, but the actual practical results were very heterogeneous, complex to implement and low yields due to such a long time between perfect mixing cement ( in concentrations as low as 3 to 4%), wetting and final compacting.

It is for this reason that the Germans begin in the 70s to design anti-roll bars atomizing water where the time between the cement is mixed with aggregates and required additional moisture occurs in less than one hour period.

Why less than an hour? ... what happens is that the cement setting begins in contact with moisture and applied in less than an hour to achieve optimum compaction density for that project.

The setting is not another chemical process and crystallization those crystals are attached form a IRREVERSIBLE network equipment and logistics execution adequate to achieve the required times are needed.

We entered 2 very important concepts such as the Crystallization and irreversibility.

This network of crystals irreversible link system while pumpable particles move or change their structure preventing premature deterioration of the pavement.

In the photograph we can observe in sections stabilized where mixing and compaction was conducted, granular materials suffer displacement action of water and traffic.

For these observations we can say that after having done a good project stabilized and have used the best equipment available, but good logistics is achieved in the implementation, we will have surface defects which the user will be perceived and which probably made the first maintenance operations.

Exchange table with departmental governments

On July 26 colleagues Quartermaster Cologne approached salons CITEVI shared-time exchange with a focus on current needs and challenges that present themselves to technical and economic level for the municipalities and their jobs from construction vial.

an interesting talk, where they were addressed among others the following topics generated:

* The current problems of rural roads and how to address it in a sustainable manner;

* Final technical solutions as stabilized soil cement;

* Benefits of primer emulsions;

* Surface treatments and the experience in New Zealand;

* New modified asphalts and their applications.

Hoping it will be of interest to other municipalities, we extend the invitation to participate, you can write to lucia@bitafal.com.uy to coordinate day and number of participants. If you wish to address a subject that is not in the proposal, we are open to inclusion and thus answer questions.
