INAUGURATION OF ROUTE 104 AND ROUTE 10

The synergy between recycled cement and surface treatments show that a route can be rehabilitated at low cost with high performance and quality

Last January 28 The official inauguration of the works took place at the intersection of both routes, in front of Manantiales beach. The Minister of Transportation and Public Works, Luis Alberto Heber, the Mayor of Maldonado, Enrique Antía, the Director of Roads, Hernán Ciganda and the Directors of the company participated in the meeting.

There are several accolades that the Serviam company has received for the Capeseal that was carried out in more than 33 km of route that were rehabilitated in just 3 months. Not only for the quality of the finished work but also for the speed of execution as well as for the aesthetic and functional improvement of one of the main tourist corridors in Punta del Este.

As we discussed in the Bulletin # 118, the works on Route 104 consisted of cleaning the strip and deepening the gutters as well as the surcharge of between 15 and 20 cm of roughness that was recycled with cement along with the old existing bituminous treatment.

To control cracking, transverse cuts were made with emulsion IRRIGATION BITAFAL 65 with a team specially designed for it. The curing irrigation was carried out with Emulsion IRRIGATION BITAFAL 65 and crushing sand providing excellent adherence and a very good performance as protection of the stabilized base.

Finally, the Capeseal type paving was carried out with a simple bituminous treatment with emulsion. IRRIGATION BITAFLEX 65 P40 and a cold micro-agglomerate with emulsion BITAFLEX MICRO 62 P25

A roundabout was made at a black point on the route and all the signage was renewed by applying highly durable thermoplastic paint, studs and highly reflective signage.

The section of Route 10 from 104 to the entrance to José Ignacio was recycled in 15 cm with Portland cement and then Capeseal as a tread layer.

Both routes achieved an improvement in roughness and slip resistance, as well as a finish similar to asphalt pavement with great contrast to the signage, which translates into improvements in road safety. In addition, an important structural improvement was made that will allow a high durability of the rehabilitated sections.

SEMINAR: IMPROVEMENT AND REHABILITATION OF RURAL ROADS

The Ruta 7 Foundation together with the Faculty of Engineering and with the support of the Congress of Mayors and the CURE organized a Seminar on the advances of methodologies and techniques for the improvement and rehabilitation of rural roads on November 17.

It was held at the new headquarters of the CURE (Eastern Regional University Center) in the city of Treinta y Tres and in which various technicians from the Federal University of Rio Grande do Sul, the Faculty of Engineering, and Fundación Ruta 7, consultants and Construction Directors of various Departmental Governments.

The topics covered ranged from the design of pavements with low traffic volume, stabilization with hydraulic binders such as lime, ash and Portland cement to the experiences gathered in regional events such as the 1st Argentine Congress of Rural Roads and the Basic Roads Course held in Chile.

More than 60 technicians from Municipalities, Roads, companies and the University participated in the seminar.

At the end of it, an interesting exchange was made between those present on how the stabilization techniques with cement still do not enter the range of possibilities for rural roads despite the incorporation of technology at the national level and how it should be done so that it is done. reality.

Reflections on state of emergency of national roads

Severe weather in recent months are to be felt in the national roads, from the primary network to rural roads(Source: El País, 04/19/16)

So much so that in several departments requested that the "emergency road" is declared, as indicated in Canelones (Source: El País, 10/04/16)and Salto (Source: El País, 13/04/16) as well as on the coast of the country (Source: El País, 04/20/16) And in the west in Cerro Largo (Source: El País, 05/09/16)

It has been announced by the government a battery of proposals from an extra small party for the Intendencias to cope with the deteriorating state of their ways to the extension of the scheme of PPP (Public Private Partnerships) to rural roads (Source: El Observador, 05/15/16)

He also spoke of a Strategic Plan for Rural Caminería (El País, 05/04/16) But without going into more detail than that is going to make a "Analysis of the needs of each department and introduction of new technologies for road construction".

PROPOSALS

In this aspect, from the Bitafal Group to continue innovating bet in real technical solutions for the durability of rural roads.

1) As We introduced in 2013 technology Soil Stabilization and Pavement Recycling siteToday we remain committed to expanding its use with new binders and execution techniques. We have Foamed asphalts as BITAFLEX AME which can extend the working range during cold periods and give improved performance of mixtures.

2) As ferrous Surface treatments advocates we are, we are developing new asphalts, emulsions and execution techniques to achieve higher durabilities at lower costs. Also looking to expand the range of work during cold seasons.

3) We continue spreading the use of both techniques together. Road engineering worldwide considers that the implementation of these two technologies is the ultimate solution for rural roads and not to mention, because of our scale, which for much of our crumbling road network. What we have learned we must communicate why We participate in conferences and seminars at national and regional level.

4) We continue to learn to apply in UruguayAs we reported in the last edition of "Making Roads" we learn from the Kiwis who have already worked hard to seek durable and economical solutions. One of our technicians will participate in a course Surface Treatment in New Zealand and now we plan to bring South African technicians to continue the dissemination of successful experiences in the world.

5) We continue warning the political actors about the risks of "new" soil stabilization techniques with chemical or biological products. El using these experimental technologies must be done in a progressive manner, and supported on objective, technically sound and consistent, which in one way or another, justify its use. For this test we participate in conjunction with experimental technologies, using the universal recognized technology stabilization Portland cement on a stretch of road in Artigas.

Cold Recycling Wirtgen Group Seminar | December 2015 - Sao Paulo, Brazil.

It was held in Sao Paulo, Brazil, last December, a technical seminar organized by cold recycling Wirtgen Group.Uruguayans participated more than 15 technicians of various construction companies, MTOP, of Tradinter and Bitafal group. There were also delegations from various countries in South America, reaching about 200 participants.

Los temas tratados en el seminario fueron sobre la tecnología de reciclado en frío y de la estabilización con asfalto espumado específicamente. Se realizaron charlas técnicas sobre las propiedades y comportamiento de materiales estabilizados con asfalto espumado (BSM – Bitumen Stabilized Material) y un taller sobre asfalto espumado y materiales BSM en el impresionante laboratorio central de la concesionaria CCR Nova Dutra.

Asphalt arena (1)

Esta tecnología es ideal para tramos exigidos como el existente entre San Pablo y Guarulhos que cuenta con más de 200.000 vehículos por día (la mayoría de ellos camiones y ómnibus) tanto por la resistencia del BSM como por la velocidad de ejecución, que se realiza en unas cinco horas únicamente durante la noche. Por otra partes es una tecnología económica y sustentable ya que utiliza el material de base y asfalto existente, 1% del cemento y un 2% de asfalto espumado solamente.

A very interesting experience thus acquired knowledge, as both made the links between the Uruguayan delegation, as with other delegations present. It is very important that all couples involved in the development of technology in the country have participated, showing interest and commitment to these first test sections in Uruguay are successful.

First stages of cold recycling with foam asphalt | Bringing Theory to Practice

The first sections of pavement recycling foamed bitumen are a reality and are projected as an economic and sustainable solution for the rehabilitation of roads.

Since incorporation by BITAFAL RENTALS of the first recycling train in situ in Uruguay in 2013, it has advanced very quickly in the national road system to incorporate technology in all its variants.

Recently they have begun to implement the first sections in situ foamed bitumen. The company Hernandez & Gonzalez has carried out the first tests on Route 12 and is starting this March with work on Route 3 after several months of design laboratory and learning with South African technicians who have come to assist with the implementation of the technology.

Moreover the company CVC has recently completed a stretch of Route 36 in the department of Canelones, with great success. He BITAFAL group He has supported projects in both asphalt and logistics sion with facilities and equipment for the proposed Route 36

We thank our customers for the continued trust placed in the company to realize the implementation of new technologies in Uruguay.
