RECYCLED foamed bitumen - ROUTE 102

The CVC recently started with recycling Route 102 using recycling technology in situ foamed bitumen. Thanks to the high yields of the technique is expected to have completed the tasks leaving a strong and flexible for future interventions take place only in the surface layer basis in about a month.

The work consists of milling the previous route, due to the large cracking had the same block, the application of cement, recycled asphalt with added foaming and water, compaction and final grade. Then applying a curing irrigation awaiting a thin asphalt with conventional asphalt.

On the one hand, this intervention makes it clear the maintenance backlog that had this route of great importance for heavy vehicle traffic at the entrances of Montevideo and to the port. We must become conscious that interventions at the right time require less investment in maintenance.

De todas maneras, esta experiencia en conjunto con varias a nivel nacional, demuestran una vez más la importancia de estos equipos de reciclado en el aprovechamiento de nuestro patrimonio vial. La reutilización de materiales de calidad aplicados con maquinarias de alta tecnología abre nuevas fronteras en la construcción de nuestros caminos y carreteras.

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.

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)
