MTOP EXECUTED OVER USD 300 MILLION IN 2020

31 August 2021
in: Top,News,Uruguay,roads

The Ministry of Transport and Public Works (MTOP) executed more than 86% of the budget it had assigned for the year 2020

This was stated by Minister José Luis Falero, who attended the Budget Committee integrated with the Treasury of the House of Representatives. The hierarch -accompanied by Undersecretary Juan José Olaizola and the rest of his team- was satisfied with the progress in the execution of works despite the health emergency. “The difficulty of the pandemic itself and the transition were concealed. There was a strong execution, for which we must thank the entire MTOP team and the companies that have been contracted to carry out the works, ”he said.

Likewise, the chief reiterated his commitment to increase the execution of works in the remainder of the five-year period to improve the state of the country's infrastructure. The MTOP seeks to tender a greater number of road works in order to reduce costs. "When there are tenders there is more competition between the companies and that generates savings for the administration that can be used in other works," he said.

in: Asphalt,Roads,News,Uruguay,roads

The extension of the double track from Canelones to Durazno will improve traffic conditions and provide safety to users

Currently the double track runs from Montevideo to Canelones. Its extension will be executed in four sections:

The first one goes from Canelones (at the junction with Route 11) to the town of Mendoza.

The second goes from Mendoza to Florida.

The third from Florida to Sarandí Grande.

And the last one from Sarandí Grande to Durazno.

The work is part of the road works plan prepared by the current administration for the five-year period in view of the intense traffic flow that exists today today and that will increase notably in the coming years, with the important investments that are carried out in the central area of the country. The plan foresees an investment of approximately 2.5 billion dollars, a record figure in the country's history.

UPDATE SEMINAR FOR ABC (BOLIVIA)

GRUPO BITAFAL present at the Seminar organized by the Franz Tamayo University of Bolivia

The seminar organized by the Franz Tamayo University and the Bolivian Highway Administration (ABC) was held in 4 days from 14 to July 27th Through the Zoom platform where more than 100 ABC engineers were able to learn first-hand about the latest technologies related to modified asphalt and emulsions.

Speakers from various universities in Argentina, Brazil, Bolivia and Peru as well as CAF, Instituto Panameño del Asfalto y Vialidad Argentina presented on various topics related to the use of modified asphalt as well as primer emulsions and modified emulsions for treatments. Grupo Bitafal presented on "High performance asphalt emulsions" commenting on the latest trends in specifications by degree of performance and other recent developments.

DOUBLE TREATMENT LOCKED IN CIRCUIT 1 PPP

Traxpalco and Hernández and González perform at a very good pace with BITAFLEX RIEGO 65 P40 emulsion

The sections reconstructed by means of Surface Treatment include Route 54 and Route 57 and include a widening of the planimetric correction platform, surcharge and stabilized with Portland cement. Then, a double treatment is being carried out on the pavement at 7.2 m wide and a single treatment on shoulders at 1.8 m wide. The treatment is running with the technique Multiple Treatment Locked (TMT) with highly modified emulsion IRRIGATION BITAFLEX 65 P40 that allows high performance performance and early release to transit as well as saving materials without risk of exudation.

The works of Route 54 that the company Traxpalco is executing have made important progress in their execution since both the stabilization and the surface treatment are scheduled to be completed during the month of May. The works consist of a platform widening to 12 m wide together with planimetric adjustment of the entire section, then the granular material is stabilized with Portland cement to achieve a simple compressive strength of at least 20Kg / cm2. Then the TMT is carried out with highly modified emulsion IRRIGATION BITAFLEX 65 P40 with 6-12 mm aggregate and 12-19 mm with mist irrigation. The performance of the double treatment is above 15,000 m2 / day.

We thank Eng. Guido Saizar and Emilio Aitcin for sharing their concerns and collaborating with our company in continuous improvement.

The complete “Circuit 1” project consists of the reconstruction and maintenance of 260 km of existing route for a time horizon of 20 years, on Routes 12, 54, 55 and 57, as well as the construction of the Bypass in the city of Carmelo.

LEARNING ABOUT CONSERVATION

30 April 2021
in: Asphalt,Conservation,News,pre,paving technologies,roads

Is our network gaining or losing value?

This is one of the questions of the ROADVOCATE course taught by the Pavement Preservation and Recycling Alliance (PPRA), which we attend virtually and where we update our knowledge about preservation and conservation treatments.

April ends and with it goes another of the editions of the fantastic PPRA ROADVOCATE course. With the presence of more than 60 people, from various American transit agencies, construction companies and material suppliers, we learned from experts how to use various tools for better pavement conservation, including various calculators and technical material to get the most out of it. of our resources, especially in this pandemic context.

The ROADVOCATE course is a knowledge update course that imparts the pre to teach public transportation agencies, contractors, and the general public the fundamentals of making data-driven decisions, how to optimize budgets by spending wisely, and the importance of conservation.

The platform where the magic happens is on the PPRA website www.roadresource.org and it is where all the activities of the course are carried out. Among other things it contains:

A guide to select the most suitable treatment for a road, based on its condition or from a photographic comparison.
A complete treatment toolbox, fully explained from its materials to its execution and good practices.
Comparative calculators of equivalent annual costs, life cycle cost, remaining life and cost benefit between different treatments.
Sustainable calculators to assess green projects.
Manuals and technical information on all pavement recycling and conservation techniques.

The conservation of highways is becoming more and more relevant these days, when budgets are somewhat limited and when we must protect the road network, one of the most important assets of nations. It is interesting to note that the views of Americans regarding conservation are familiar to what happens in our South American countries: lack of budget, lack of long-term planning, political pressure, complaints from neighbors, etc.

Fortunately, slowly but surely, several agencies are reversing the trend from reactive to proactive maintenance. In this way, the wasteful thought of "let's intervene the roads in the worst condition" is left behind, which exhausts the resources of the administration, due to an attitude of "Let's keep good roads in good condition" Fortunately, slowly but surely, several agencies are reversing the trend from reactive to proactive maintenance. In this way, the wasteful thought of "let's intervene the roads in the worst condition" is left behind, which exhausts the resources of the administration, due to an attitude of

Grupo Bitafal, as a member of the PPRA and a participant in its international committee and marketing committee, is taking steps to bring this valuable knowledge closer to local and regional government administrations, so that in the future we can receive this type of courses in our countries and in Spanish.

We leave some of the screenshots of the virtual course, with more relevant information. Finally, we invite you to browse the web www.roadresource.org and learn more about conservation.

Until next time!

THE ROLE OF ASPHALT IN ROAD SAFETY

We all know that the surface condition of the road affects the accident rate: exudations, pits and rutting increase stopping distances and promote abrupt maneuvers, especially in wet conditions. At Grupo Bitafal we are working on techniques and products to reverse this problem.

As Voltaire said, “There is no such thing as an accident. What we call this name is the effect of some cause that we do not see ”. In general, the incidence of the human factor is the main cause of claims, although the causes are really multiple and some are not very controllable. However, from our perspective and our commitment to Road Safety, the surface condition of the road is a controllable factor and we are working on various techniques and products that substantially improve this situation.

Traffic accidents are one of the most deadly evils in our country. From January 1 to November 30, 2020, a total of 19,721 people were injured by traffic accidents, of whom 347 died and 2606 were seriously injured, according to official figures from UNASEV. Although the rate decreased compared to the previous year (figures strongly influenced by the voluntary mobility restrictions of the pandemic), they continue to represent a problem to which we must pay careful attention.

We detail below some of the main causes and possible solutions:

Hydroplaning and “Spray” effect:

For example, if the asphalt does not drain the water well or due to defects in the road an accumulation occurs, the famous problem of aquaplanning or hydroplaning occurs. At the same time, in closed mixtures, the “Spray” effect occurs on rainy days that make visibility difficult. Beyond the profile of the road that must ensure drainage as well as have a low rut to avoid accumulation, there are solutions that are capable of improving this drainage.

One of the solutions that has been applied experimentally in Uruguay is an F10 mixture with modified asphalt BITAFLEX AM3 in which a higher macrotexture (above 1.0 mm in the sand patch) was achieved than in usual semi-dense mixtures and allows to reduce the "Spray" effect mainly. Even so, it is necessary to see alternatives that drain more water, so we are working to carry out a overcoated with a drainage-type mix with modified asphalt BITAFLEX AM3, asphalt rubber AMC 50 the highly modified asphalt HiMA. The high viscosity of these binders allows the mixture to be applied while maintaining its high percentage of voids and its excellent performance against permanent deformation, preventing the formation of rutting and water accumulation as well as eliminating the “Spray” effect.

The greater the voids on the surface, the safer the rolling, so there are alternatives with surface treatments that allow improving sections that have these problems. For example we have applied in Uruguay type surface treatments “Chipping" O cold microagglomerates to solve the rutting problem in such a way as to restore the transversal profile of the road and allow the normal drainage of water towards the sides. On the other hand the application of multiple locked treatments (TMT) It allows to generate voids but with a more comfortable and less noisy rolling.

Lack of texture and friction:

A problem related to the previous one but which is approached in a different way is the issue of the lack of friction of the road due to exudations or loss of texture of the stone aggregates. This can normally occur in heavily requested areas such as intersections, traffic lights, access to roundabouts, roundabouts, etc. In these cases, loss of vehicle control, increased stopping distance and skidding can cause serious accidents. To improve friction we are also working with high friction Seal Coat treatments, composed of high performance binders and excellent resistance aggregates. These treatments have the additional possibility of generating a red, blue or green color surface, which improves the visibility of the road and the driver's attention.

Wells:

Finally, the problem with wells is that they usually generate abrupt maneuvers at high speeds that can end in a collision or loss of control of the vehicle. For this, at Grupo Bitafal we work to promote preventive treatment, with the use of a battery of surface treatment techniques that allow, with the same money as with a milling and replacement scheme, to maintain a high standard of the pavement, ensuring the absence of wells.

In secondary and urban roads we have been working with departmental municipalities for several years supplying the family of emulsions MIX 55 to make cold mixes for patching.

In short, these are the latest developments in materials and techniques that improve road safety. We want to invite anyone interested to see our facilities and see these innovations first-hand.

THE WORKS OF THE PPP CIRCUIT 7 BEGAN

Grupo San José trusts Bitafal to supply asphalt products

The Group, made up of the companies Serviam, CVC, Interagrovial, plans to duplicate the road in the section of Route 3 between Routes 1 and 11, and the construction of the Route 11 bypass to the city of San José, as well as the construction of a new 400 m bridge over the San José river.

Bitafal will supply the modified asphalt and emulsions for the execution of the pavements of the work that the PPP must maintain for 20 years. For this, both the black base layers and the tread layers with modified asphalt will be made.

Last monday February 1st A construction commencement ceremony was held, with the presence of the Minister of Transportation and Public Works, Luis Alberto Heber, the undersecretary, Juan José Olaizola, and the mayor of San José, Ana Bentaberri.

An execution period of 3 years is estimated for this project, which will be financed by Grupo San José S.A. with the support of CAF, CAFAM and BROU, which amounts to USD 70 million and 20 million for the rest of the contract, destined to maintenance.

Bitafal will supply the modified asphalt type PG 70-28 for base coat and type PG 76-28 for rolling as well as modified emulsions used for bonding and accessory works. We will keep you updated on the progress of the work.

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.
