ROUTE 3 DUPLICATION IS A REALITY

The works of Circuit 7 being carried out by Serviam and CVC are progressing at a very good pace

The project includes the duplication of roads in route 3, between routes 1 and 11, a bypass through the south of the city of San José de Mayo and a new bridge over the San José river. The section to be duplicated has an extension of 25 kilometers and about 8 km are close to being enabled just a few months after the start of the works.

The asphalt mix project is carried out entirely with modified asphalt supplied by Grupo Bitafal and the shoulders were made with a Cape Seal with modified BITAFLEX emulsions.

We thank the companies for the confidence they have given in supplying such an important input for their work.

The sections that are ready to be inaugurated are from Route 1 to km 73 executed by Serviam and the section from km 87 to the departmental capital together with the concrete pavement and roundabouts of the city of San José executed by the CVC company.
In both sections there were various challenges to overcome such as the transplantation of dozens of palm trees, the use of new equipment and technologies such as the transfer that Serviam incorporated (HC #130) for the execution of the asphalt layer.

The use of the transfer allows an excellent homogeneity of the laid mixture as well as a surface regularity (IRI) below 1 that is noticeable when walking on the pavement. Congratulations to the entire Serviam technical team for the excellent work done.

Regarding the concrete section of CVC, it is worth highlighting the solution to the drainage as well as the interaction of the route with the shops and the incorporation of two large roundabouts in an area of high, heavy and slow traffic such as the pass of Route 3 by the city of San José. As for the cemented base, it was made on the project dimension and then trimeated with the 3D milling machine to achieve an excellent support IRI. The concrete pavement was made between July 16 and August 25, in just 40 days, there were 44,000 m2 with curbs with heavy traffic and short days. We congratulate the efforts of the company for such an achievement.

in: Asphalt,News,floors,served,roads

The modern Vögele brand equipment MT3000-2 is being used in the duplication of Route 3

The Serviam company was a pioneer in using a transfer in Uruguay during the execution of the maintenance of Route 8 in 2014 with the Roadtec SB-2500 equipment from BITAFAL RENTALS but today They incorporate a state-of-the-art equipment with great technical features.

The Vögele MT3000-2 transfer features an oscillating conveyor belt, an innovative material transport system that can deliver up to 1300 t / h, and a modern control system that allows the machine to be controlled easily and safely. With this equipment, the company ensures a high quality in the mixtures, minimizing thermal and granulometric segregations, especially important in the PPP7 that they must maintain for 20 years.

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.

ROUTE 104 REHABILITATION

Serviam began the rehabilitation works that will culminate before the tourist season

The route that connects Routes 9 and 10 at Manantiales is being rebuilt along its 15 km length through recycling with Portland cement and a Capeseal as wearing course, similar to what was done on Route 60.

It is an ideal solution due to the aesthetic and functional quality of the combination of treatments for a route that has high light traffic in the summer season.

The works began with a strip cleaning and ditch deepening as well as the surcharge of between 15 and 20 cm of coarse that is being stabilized with cement together with the existing old bituminous treatment.

As in the rehabilitation of Route 18 (Making Paths Newsletter #102), a series of transverse cuts with emulsion is made to control cracking. IRRIGATION BITAFAL 65 with equipment specially designed for it. A radiofrequency motor grader guidance system is also being used that allows a great improvement in the roughness of the section that will later receive a surface treatment.

Irrigation Curing with Emulsion IRRIGATION BITAFAL 65 and grinding sand has excellent adhesion and performs very well as a stabilized base protection.

In the next few days, the Capeseal type paving works will begin with a simple bituminous treatment with emulsion IRRIGATION BITAFLEX 65 P40 and cold microagglomerate with emulsion BITAFLEX MICRO 62 P25.

We will keep you informed of the development of the work in future editions of our newsletter.

Road maintenance

We made a tour of the fronts of works which are being used Bitafal products.

This time we made 1400 km traveled by different works in progress, or a year of operations, for the purposes of check the technical situation and being in contact with the realities of the same.

In general all routes flown are in good condition but we have to convince us that interventions on the roadways when done in a timely manner so substantially lengthen the quality and durability of our floors. On the other hand we must continue to innovate and look for continuity mechanisms that do not generate electoral cycles ups and downs in the construction industry.

1) Laying asphalt mixture with modified BITAFLEX AM3 on driveway route 5It executed by the company HYG, great work rate and tidiness, a substantial improvement on driveways executed noticeable, providing a long service life of the road.

2) Then we visited the works on route 3 Pass of the Port to Young about 6 years ago and made it in very good shape and visited the recent works carried out by the firm Gofinal / Lemiro Pietroboni in retreading executed asphalt modified asphalt BITAFLEX AM3. I became essential that retreading modified asphalt because it was the only stretch of Route 3 in the vicinity of Young was fatigued.

3) Just finished running route 25 also modified asphalt BITAFLEX AM3. We were accompanying the company Colier Opening of the section of Young to Route 90 which has a traffic of 300 trucks per day wood and general condition of the road it was very bad due to the age of the last interventions.

4) They are starting the work by signing the INCOCI route 90, Which is stabilized with portland cement and seal with a surface treatment made with highly modified emulsions.

5) On Route 30 Route 3, Diaz Alvarez signature is running treatments emulsions IRRIGATION Bitaflex 65 P40, Achieving aggregate adhesion / asphalt very good and well behaved at the high temperatures of the region.

6) We participate in the cuts ribbon inaugurating bridges all route 30, Works of very good quality and excellent execution deadlines were completed 7 months before the deadline, congratulations to the four companies that participated: Saceem, Incoci, Grinor and Cujo.

7) Bases route 30 are being prepared by the firm Tracoviax in its entirety for treatment reinforced emulsions highly modified type IRRIGATION 65 P40 as required by the standard and the respective region.
Sieve executed with bases are being stabilized very well and really congratulates them for the arduous task of mastering the basalts of the north.

8) We review the overall asphaltic treatments region surrounding the city of Artigas and we can certify that his condition is very good. We visited the section executed by Incoci on Routes 30 and 31 as well as performed by Tracoviax on Route 30 and kept in good shape, without exudates or potholes. They are very well executed with the correct dosage, presenting a texture that can be seen in the photos taken.

9) And returning, we passed the landmark CHIPING executed by Colier on route 5 in the sections of hits on Route 43, San Gregorio de Polanco. That stretch was performed for the purpose of a necessary and immediate intervention to last 1 or 2 years, as we have been 8 years and continues to provide adequate service. Only they have been some meters bridging sealing.

We have to convince us that interventions on the roadways, when done in a timely manner, so substantially lengthen the quality and durability of our floors.
That calculation is handled that for every dollar we spend on maintenance, spare 8 future dollars, in this and many other cases are checked handsomely.

We have cases of the Chiping de Ruta 8 of Serviam 4 years, the retreading 2 cm asphalt Arnel Bitaflex AM3 on route 8 which it lasted more than 10 years and only last year was milled and Recapo by the firm Techint. It is very good for our company to see the progress of the work and make returns to our friends.

Until next time.

XX IBWC IN MEXICO

A large contingent of Uruguayan at the XX Congress of the Asphalt Iberolatinoamericano held in Guadalajara, Mexico

From the 25 to the November 29th He was held at the Performing Arts Center of Guadalajara a new edition of the most important congress in the world of asphalt. This time more than 800 technicians from 27 countries were present to show progress in binders and asphalt paving technology.

The strong presence of Uruguay was to ratify the realization of the XXI IBWC in the city of Punta of the East in November 2021. The launch was performed by a campaign of expectation during the Congress with a stand of Uruguay, an information campaign through leaflets and finally the announcement at the closing ceremony along with a video prepared for the occasion.

Organized by the AMAAC (Mexican Association of Asphalt), the WHAT XX It was held in conjunction with the Expo Asphalt Mexico and consisted of 5 days of intense knowledge sharing and closer ties between the different actors in the world of asphalt.

They presented more than 150 technical papers in various forms such as plenary lectures 2 auditoriums and simultaneous presentations in the same room with multiple screens and in which participants approached according to topics of interest.

There were also six lectures by prominent experts who spoke on asphalt mixes, infrastructure, design methods and auscultation of pavements.

Uruguay was present with 10 technical papers presented of which 7 were performed oral presentation format. Bitafal group He presented on emulsions degree of performance on mixtures with highly modified asphalts and on agile trials DSR (rheometer) to determine characteristics of asphalt mixtures. Serviam presented a paper on the design and implementation of a foamed bitumen recycling by Ing. Faustina Keuliyan and also on the rehabilitation of Route 60 with the Capeseal technology by Ing. Rodrigo Tejería and Pablo Carranza.

Furthermore Eng. Oscar Giovannon (Arg.) Presented the thesis of Ing. José Luis Martucci on recycled foamed performed in Route 3 and James Kröger presented thesis Ing. Gerardo Fernandez on primer emulsions.

He Tuesday in the afternoon, in a special session, Bitafal Group presented his book "High Performance Surface Treatment" of which were delivering copies of the same to all participants and which had an excellent reception.

The week was full of hard work broadcast next IBWC to be held in Punta of the East, first with the dissemination of material on Uruguay and customs, then on our natural beauty and closing Tipped East and an express invitation to participate in the XXI IBWC to be held in 2021 with a promotional video. We're on track and we will fulfill the expectations of all "cileros".

Nuevamente "one more!"

ROUTE OPENING 18

Last October 10th Serviam inaugurated the work carried out on Route 18.

Route 18 Archives - Grupo Bitafal

Addition was performed on the sections still had good structural condition but any sign of surface damage, a micro cold emulsion BITAFLEX MICRO P25 62 with excellent quality implementation. We commend the company for work performed and the confidence provided.

The inauguration took place in Pueblo Rincón in the presence of the Minister of Transport, Victor Rossi, the Director of Roads Leonardo Cola and other members of the MTOP. In turn participated the mayor of Vergara, representatives of the Treinta y Tres, colleagues and friends.

A detail of execution and the new control technique mentioned cracking may be found at: https://bitafal.com.uy/nueva-tecnica-de-control-de-fisuracion-para-cementados/

NEW TECHNIQUE FOR CEMENT CRACKING CONTROL

Serviam has developed an interesting team to prefisurado recycled with cement.

Drawbacks consabidos generating shrinkage cracks of cemented materials are subject to attack because they can reduce the life of the pavement by water ingress. Usually in our country it has incorporated the technique with a heavy microcracking to mitigate these effects but there are other alternatives globally with specific equipment Compactor.

Serviam company developed a computer adapted to perform a Bobcat injecting the emulsion prefisurado IRRIGATION BITAFAL 65 at a depth of 20 cm each 4 m crosswise.

After initial compaction of the recycled material prefisurado this is done then continue working, leveling and final compaction. Of note is the use of technology to achieve grade project controlled by RF motoniveladora.

Subsequently curing the same emulsion BITAFAL IRRIGATION 65 is performed with quarry dust is released and traffic. By far the results are very good and it shows on the go using technology to control IRI. In the next few weeks they will be starting tasks paving asphalt hot mix in 5 cm surface layer.

We will see the behavior of this technique prefisurado in the future. For now, in every induced cracking and the asphalt it is necessary to prevent water ingress so hopefully a lifetime of work done.

The equipment developed by Serviam has a storage tank emulsion, a positive displacement pump, a wedge (shark fin type) of 25 cm which leaves a pipe 20 cm and a solenoid valve for controlling the dosage from Bobcat.

The fin makes a wedge about 2 cm wide in advancing the equipment is filled with emulsion BITAFAL IRRIGATION 65. Then the material of the side itself closes the wedge and leveling and compaction are performed normally. It can be seen watering cured, made with 1L / m2 of IRRIGATION 65 and 6 L / m2 of dust, marks prefisurado every 4 m in the photos below.

RECYCLING AND CAPESEAL ROUTE 60

The works mentioned in previous bulletins (Bulletin # 98 NOTE: Capeseal on Route 60) Have come to an end and the result is really very good.

The recycling works Portland cement and the Capeseal provided as wearing course have culminated in this work quality that carried out Serviam. Aesthetic and functional completion of the section is excellent and we recommend those not familiar with the technique of Capeseal visit the section from Sugarloaf to the city of Minas.

It is for the group BITAFAL proud to have been involved in the whole process, from the dissemination of the aforementioned techniques in lectures, conferences and in our book "High Performance Surface treatments"To see it come true with the quality achieved. Thank provided Serviam confidence in our products and services in each of the construction phases of the stretch.

Capeseal on Route 60

Making good progress with the implementation Serviam Micro cold on the simple treatment performed on Route 60.

As reported in bulletin # 92 and # 97, the Capeseal on Route 60 resumed its march after the winter closure. Work began from Sugarloaf with high execution performance and excellent surface quality.

Serviam commend the work done and the application of a set of technologies that we believe are the future of our roads.
