EFFICIENCY IN TREATMENTS BITUMINOSOS

Once again, the Colier company entrusted us to collaborate in the surface treatments that are being carried out on Route 7 at the height of Santa Clara de Olimar

Bitafal Rentals made available to the company a double ACMAR spreader of French origin that has the characteristic of being a graveller with telescopic rollers, which allows a perfect dosage of the calibrated aggregates as well as the necessary emulsion in a fair and precise way.
Through this technology, the company went from having a crew for the execution of the treatment of about 8 people to only 3. In addition, the advantage that the same equipment doses emulsion and aggregate allows greater control of the dosage and better results in the treatment built.

We present ourselves on site and agree, using a calibrating drawer, the appropriate dose of aggregate and after defining this characteristic, the necessary emulsion. The results are eloquent and the doses and emulsion / aggregate ratio are behaving in a superior way without the risks of overdosing so harmful for subsequent exudations.

Bitafal is already in the operational phase of track tests of a series of new asphalts for winter use that are applied hot and with automatic release to traffic. This project is linked to a new generation of developments that we have been working on for 3 years in order to ensure that our market does not see its productivity altered during closed seasons.

Our companies are going through a very difficult time economically linked to the low productivity of execution of works. When Bitafal incorporated the first recycling train, it achieved a great leap in productivity on the road and now we are preparing for this new generation of very high performance elastomeric asphalts that will complement this innovation.

SAMI ONE BOX 8

TECHINT again trusts BITAFAL RENTALS the execution of a SAMI membrane.

Is currently running one recoating with conventional asphalt on Route 8 between 150 and 183 km below which is being applied stress relieving membrane (SAMI - by its acronym) emulsion IRRIGATION BITAFLEX 65 P40.

This particular stretch had been retreading Arnel at the end of 2009 with the first production of modified asphalt BITAFLEX AM3 our company supplied locally. That folder 3 cm, designed to last a couple of years, ended up serving for 8 years.

Current work involves milling the modified folder 3 cm, application of the emulsion P40 SAMI membrane and subsequent recoating of 5 cm with conventional asphalt.

SEALS Pando

The West Consortium entrusted Interbalnearia BITAFAL RENTALS the Grouting the bridge over the A ° Pando on Route Interbalnearia. They were executed after applying a new retreading over the bridge, which was recently widened, joining the two existing bridges.

Joints made are of the type elastic Juntastrech made with selected aggregates and sealant type BITAFLEX SA40.

Estimates for this type of specialized equipment together with work yields are between 25 and 35 linear meters per day. It is one of the more economical and durable solutions for expansion joints.

The performance speaks for itself since been applied in many bridges in our road network and continue to give good service with very low maintenance.

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.

IMPROVEMENTS IN ROUTE 81

INCOCI RENTALS BITAFAL trust for the execution of a stretch of cold recycling on site.

They are making improvements to Route 81 in the section that connects the new bridge over the St. Lucia. Once the works are completed there will be a corridor between Route 11 and Route 5 giving it the importance it deserves the new bridge and bypaseando St. Lucia and Canelones substantially improving travel times.

The work done by INCOCI includes an expansion platform, recycling of the existing macadam, performing an offset Portland cement stabilized layer and a concrete floor 21 cm.

For the implementation of recycling and stabilized base, BITAFAL RENTALS He collaborated in the dosage of Portland cement, recycled walkway and initial compaction.

For widening of the platform teeth on both sides of the existing roadway is made with successive layers of granular materials CBR 10, 40 and 60. A cement stabilized granular layer remaining flush with the existing roadway is then executed for have similar rigidities.

Across the width of the new roadway a regularizing layer was made. To do recharged with crude which was then stabilized in place by adjusting the dosages of cement according to the thickness profile. At this stage of the existing recycled macadam. For thick thicknesses were made was fundamentally a heavy compaction equipment kickstand to achieve densification.

Currently running the concrete pavement 21 cm thick is achieving very good resistance values and excellent surface finish.

INCOCI thank the confidence provided BITAFAL group.

SUCCESS STORIES IN WINTER GRAVILLADOS

The use of the technique TDT (Double Treatment Trabado) graveled in various works that have recently implemented show that emulsions may be used during the winter successfully without risk of landslides and significant material savings.

Such is the case of the work done by NECKLACE Ruta 19, executed by the banquinas BITAFAL RENTALS for SERVIAM in Route 5 and TECHINT in Route 9 and Route 16.

All these works were done with modified emulsions Bitaflex P40 or P25 Riego 65 using the technique TDT (Note: "Innovative technologies for surface treatments in winter") Without any detachment.

This is due to the combination of good materials and implementing ways appropriate to the era. The key is to run two risks in the day achieving total mechanical interlock and to even make irrigation fog on the same day to ensure adherence of the entire stone and a superior aesthetic finish. Moreover it is essential dosing intelligently materials to have the optimal amounts in each irrigation and save on the materials used.

We invite you to know the procedure used in our blog: “INNOVATIVE SURFACE TREATMENT TECHNOLOGIES IN WINTER“

Strength studies ductility performed on the binders for surface treatments show that the modified emulsions Bitaflex Riego 65 P25 and P40 have a cohesive energy far superior to any common emulsion and not to mention the asphalt diluted, which contributes to the durability of the matrix achieved in the implementation of DTT.

As the images of the enclosed work COLIER in Route 19 can be seen that achieved is homogeneous matrix, containing suitable gaps for expansion of the bitumen in summer and very little excess stone in the shoulders.

We invite you to contact if considered necessary to deepen the dosage form and implementation of a TDT or the selection of suitable materials: bitafal@bitafal.com.uy

THE IMPORTANCE OF PORTLAND CEMENT STABILIZED.

Our company in 2013 introduced the first Uruguay Wirtgen WR2000 stabilizer knowing that coming times of change in our industry due to increasingly tight budgets to meet a growing demand for road maintenance.

Moreover, the provisions of Dinama and Dinamige for quarrying are increasingly restrictive implying that these technologies, reuse of existing materials, are here to stay.

The more than 14 machines that are operating in our place to prove it. more economic and lasting foundations are achieved using existing materials and also with yields never imagined execution.

This technology allows us to think of other alternatives for pavement design, especially in the surface layers, which are not disseminated by the lean life they had in defective granular bases.

It's not new, but We are convinced that the foundations of our roads are the foundation and the life of asphalt which we place on them.

It is our vocation known surface treatments, very successful experience in new binders and search for new alternatives of implementing them prove it.

It is a technology that fits perfectly with the costs that Uruguay can pay for your roads and excellent cost / benefit based on traffic routes we have in our relationship.

We are studying sion All manual published in the roads of Australia, New Zealand and South Africa where more than 90% of the kilometers are executed surface treatments and where they used the stabilized with cement massively.

This work is being developed thoroughly and bringing it closer to the realities of this side of the southern hemisphere to transmit knowledge to the sector being adquiriendo.Prontamente be informing them about the progress of this work.

COMPARISON OF STABILIZATION OF ROADS TECHNOLOGIES

GROUP BITAFAL was invited by the OPP to participate in a comparative experimental section of stabilizing products in the Constancia in Paysandu, seeking to know which of them could ensure durability in rural roads.

Of the 11 kilometers of road thousand meters were left at each end as witnesses, which is not an application is made, while the remaining 9 kilometers are divided into 6 sections and each of them will be a specific application (SEE: LINK SITIO PAYSANDU.GUB.UY)

BITAFAL group It will implement the technology introduced in Uruguay in 2013, stabilization on site with Portland cement in a length of 1500 m by 6 m wide. The other stabilizers are applied based on polymer, of ionic and sulfur.

It's an interesting experience to evaluate the performance of a large portion of existing stabilizers on the market, where quality, durability, the manner of execution and of course the actual cost of each in similar conditions will be.

En una reciente entrevista en El Telégrafo, Rodrigo de Souza, de la Dirección de Vialidad de la Intendencia de Paysandú destacó la “importancia clave de la prueba, hace años que se viene considerando la posibilidad y ahora la OPP ha decidido impulsar un cambio en la manera de mantener los caminos rurales. No hay dudas que el tránsito ha variado sustancialmente y que entonces es de orden que hay que promover el uso de mejores productos”.

Moreover, the Director of Works of the Administration, David de Lima said "This is a beginning, an experimental pose, but clearly we intend to carry on using these products, those that give better results in our soils. Within rural road recovery plans will be much more expensive at first but cheaper in the end. "

The project will have several controls. On the one hand, of the companies that sell the products, they expect to be applied in optimal conditions. Then the quartermaster. Third, the OPP. And besides, the Faculty of Engineering, which will closely monitor the work.

Scientific support will be key, because control of such stabilizers involves systematic chemical and physical-mechanical tests (SEE: NOTE THE TELEGRAPH September 2016)

JOINTS IN NEW BRIDGES TACUAREMBÓ

The Saceem-Cujo consortium has relied on the Bitafal Group in the supply and installation of anchored neoprene seals new suspension bridges that were built in Paso del Bote in the city of Tacuarembó.

The construction of two new bridges were made with existing (dating from 1930) in the Laguna de las Lavanderas where Patria Gaucha is performed. They consist of reinforced concrete arches 60 m span and 12m high guyed by a rigid board.

To withstand the intense movements, SC-160 type joints were installed in the stirrups and SC-230 in the central stack. These boards are designed for maximum movement of 160 and 230 mm. In addition maintenance of existing bridges which were installed together type SC-42 they were performed.

The consortium has also relied on our company for waterproofing membrane RUBERSAM board as we reported in our previous newsletter.

The two new bridges 60 m and 120 m long on Arroyo Tacuarembó have a road width of 8 m and a path 2.5m complement existing bridges, traffic circulating dual carriageway in one direction on themselves.

It really is a unique work in the country and we are very proud to have been part of this project consolidating our company as leading solutions for bridges together.
