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.

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.

SECOND WEBINAR ON PERFORMANCE TESTING

We continue with the conferences of this first cycle "High Performance Surface Treatments"

Last October 15th The second webinar was held in which we discussed the subject of the tests that are carried out in the stages of selection of materials, design and construction; and we present some of the most effective surface treatment specifications in the world. Once again, we managed to attract more than 350 people in this much-demanded cycle of talks on superficial treatments.

This second conference was focused on the usual performance of a treatment and we reviewed the main failures that can occur, such as loss of stone, exudation and fissures. We comment on how each type of failure is evaluated and its consequences for the user and the Administration. Then, we extensively detail what are the factors that we can control to avoid or mitigate these failures from appearing in the short and long term, both in the selection of materials, in design and in construction.

One of the objectives that we wanted to convey in this webinar was about the importance of tests that allow us to represent a traffic or climate condition to which this treatment will be effectively subjected. Hence the relevance that the new and modern specifications will have for the performance of materials (such as the Emulsion Performance Grade) and the tests that allow, after construction, to evaluate and quantitatively record parameters such as slip resistance and macrotexture. We are convinced that this is the way to go if we want to define failure criteria adjusted to this type of technology, estimate its useful life and therefore use it as an effective tool in road maintenance strategies.

We take this opportunity to invite you to the next Webinar of the day November 6th, in which we will deal precisely with road management and how surface treatments, and in particular gravel irrigation, can be the most cost-efficient solution for their conservation.

SELF-ADHESIVE BITABAND: EASY SOLUTION FOR SEALING

New product to seal cracks and cold joints in pavement construction.

The new tape BITABAND AUTOADHESIVA It is a highly polymer modified asphalt presented in rolls of 10 m long and in two alternatives of width, 5 and 8 cm. It is an easy solution to apply in the construction of cold joints in asphalt pavements and it also ensures their sealing, significantly reducing cracks in the axis of the roads.

The tape is applied cold and when placing the new mix, the modified asphalt melts, adhering and sealing the mix in an area of difficult compaction such as longitudinal joints or against curbs and culverts.

BITABAND It can also be used for bridge-type fissure sealing only requiring a torch to dry the fissure for the application.

Tape BITABAND AUTOADHESIVA seals and waterproofs where required a quick and easy placement manually and without the need to heat the material in construction joints, fissures and cracks. The main uses of the tape are:

On asphalt pavements to seal cracks up to 5 mm wide.
In cold joints during the construction of pavements for sealing and adhesion, for example with an adjacent folder or in the joints with cords, culverts, etc.
In the construction of elastic bridge joints for fixing the reinforcement sheet and waterproofing the joint.

For its application, the tape is simply unrolled along the fissure / joint with the release paper facing down, it is left in the sun for a few minutes to increase the adherence and it is placed from one end of the fissure / joint to the other pressing it. by hand or with a hand roller. The release paper is then removed and released to traffic.

The tape is presented in 10 meter long rolls with release paper, packed in cardboard cylinders containing up to 6 rolls.

BITAFAL GROUP WEBINAR CYCLE

The first webinar of the High Performance Superficial Treatments Cycle was held.

The first module of this cycle was carried out last Thursday September 24 through the zoom platform with more than 350 subscribers from 26 countries. Relevant topics were discussed to achieve the success of gravel irrigation such as materials, selection of the type of treatment, design and good construction practices.

We are happy to share with all of you this new virtual adventure to exchange knowledge and opinions. The first conference of this first Cycle exceeded our expectations in terms of attendance, adding more than 350 registrations, including technicians, students, officials and builders, demonstrating the growing interest in Latin America for cost-efficient solutions for the road network.

In the presentation by Ing. Ignacio Kröger, some critical points to be taken into account that can improve the quality and favor the success of the application of gravel irrigation were dealt with very concisely. In the area of materials, the importance of granulometry tests, ALD (average minimum size), cleanliness, wear and polishing of aggregates was discussed; and the performance tests of the binders, which are adjusted to the climate and traffic of the project. Some of the tables included in our manual regarding the selection of treatments were also presented and a review of the methodology for using the Australian and New Zealand dosage design was made. Finally, some recommendations were discussed regarding the execution of irrigation, on planning, sweeping, compaction and we showed some examples of proven cases of success in Uruguay.

In module 2, we will focus on the transformation that the evaluation of surface treatments has had (from material control to quality control), marking the difference between traditional tests and new performance tests. We will talk about laboratory and construction tests that allow us to improve the final quality of the treatments and new ways to evaluate their behavior in the long term.

Module 2 will take place on the day October 15th, at 4:00 p.m. (Uruguay GMT -3).

We leave below the invitation to register, we are waiting for you!

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.

BITASEAL: NEW FLOOR REJUVENATOR

Now BItafal has a new product with excellent performance to seal and improve the appearance of pavements

Easy to apply, flexible and totally waterproof the new BITASEAL it is the best way to seal surfaces and improve the appearance of pavements.

It is a solvent resistant product and has selected aggregates that provide excellent slip resistance, making it especially useful in parking lots, race tracks and other surfaces where fuels deteriorate the pavement.

Below we tell you more about the product and the experience carried out at the Rivera Autodrome:

Due to the deterioration of the Rivera track, where there were dislodges of aggregate from the mixture, some cracks and a rather aged surface, the recovery of a part of the track with the new BITASEAL.

The application of the product was carried out by means of a mop in a very simple way, leaving a homogeneous surface, sealed and with a high slip resistance. After 40 minutes of applying it, it already has an opaque surface and almost ready to be released to traffic. In any case, it is recommended to let it dry for 2 to 3 hours for better performance.

The product is presented in 40 kg buckets and yields between 1 and 2 kg / m2 depending on the surface to be treated. We invite you to learn more about the experience and the appearance of the product in the attached photographs.

BITAFAL GROUP WEBINAR CYCLE

Delving into various topics of interest, we begin with a new challenge to share our knowledge

This coming September we will begin to issue the first cycle of conferences that complement and deepen what has been published in our manual on "High Performance Surface Treatments".

True to our word, we have listened to your comments and concerns that you sent us from the June survey, where we asked the topics that most interest you for a Webinar. 1 out of 5 voted to delve into the topic "Life Cycle Analysis with surface treatments", and for this reason we decided to make a first Cycle called "High Performance Surface Treatments", which encompasses this topic and others that also appear in our manual. . We will have top-level guests, such as Ing. Jorge Prozzi from the University of Texas.

This Cycle consists of three modules:

MODULE 1: How to guarantee the success of gravel irrigation: materials, selection, design and good construction practices.

MODULE 2: Surface treatments: Performance tests.

MODULE 3: Life cycle analysis of surface treatments: the most efficient option for conservation.

Our goal is to extend our knowledge and share the national and international experience of surface treatments, so that they achieve maximum performance. This implies interventions where special care is taken in the evaluation of the existing surface, the materials, the selection of the appropriate treatment, the design and the construction so that our path is SAFE, RELIABLE and SUSTAINABLE.

SAFE: The type of treatment, the resistance to polishing of the aggregate, the appropriate binder, the correct dosage of materials, careful construction, etc. These are aspects that affect the final safety of the road but must be considered individually. The objective is to guarantee traffic and safety conditions, minimizing circumstances that could generate costs for users and accidents.

TRUSTWORTHY: With this approach, surface treatments are first-order interventions that require the same care and detailed study as asphalt mixtures. In these situations, it is expected that the treatments comply with higher stresses and demands and for this it is essential to evaluate the structural and surface conditions through inspections and auscultation, define specific design methods for the provision of aggregates and binder, ensure the calibration of the equipment and document best construction practices. The objective is to provide tools for those responsible to make decisions based on scientific and methodological criteria, which allow predicting what the useful life of the treatment will be and, consequently, it can be a reliable instrument within the conservation strategy.

SUSTAINABLE: It consists of doing more and better, with less. High performance treatments play an essential role in the preventive maintenance of the pavement and are the answer to a technical, economic and environmental analysis. These interventions are optimized for the traffic and climatic conditions that are expected, use materials and processes that generate a smaller environmental footprint and seek to reduce the total cost of the pavement's life cycle. The goal is to put the right treatment on the right track at the right time.

We will be sharing news about the webinars on our networks.

BITAFAL PARTICIPATED IN THE ACTION Holidays #Entretodosparatodos

Last weekend, those of us who are part of Grupo BItafal were able to enjoy as a family the on-line theater performances of the "Vacations #entretodosparatodos" project.

This initiative aims to collaborate with five major cases in our country: Peluffo Giguens Foundation, Kangaroo Foundation, Children's Villages, Coranzoncitos Foundation, and Liceo Francisco.

We were able to choose between 5 performances that included “Opa Payasos” “Mago Daniel K” “Tía Libi's show” “Clap Clap Circo” and “Ruperto Rocanrol”.

It was an excellent opportunity to enjoy in this format that this new reality in which we are living offers us, to disseminate wonderful artists from our country, and at the same time collaborate with organizations that have been affected by the situation we are going through.

We thank the entire organization and we hope that initiatives like these will be replicated.
