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!

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.

WITH THE ENTRY OF SPRING, SURFACE TREATMENTS ARE BACK

The closure ends on September 1 and surface treatments begin to be seen again in the works.

The use of emulsions, which in winter involves special care, becomes common from September with various work fronts that will use the technology both on the road and on shoulders. In the following note we reinforce the main concepts to avoid premature defects in surface treatments with emulsions, especially when the first summer heats come.

An adequate application of the surface treatment implies a combination of factors to ensure success, as indicated in the Figure below the book "High Performance Surface Treatments"

https://bitafal.com.uy/libro-tratamientos-superficiales/

From this extensive list, we can highlight some points and make recommendations for a good execution in the months to come.

Weather condition in the application: The days are longer and the temperatures are starting to rise but we may still find ourselves in the months to come with wet and cold weeks. Special attention must be paid to days with maximum temperatures of 10°C and days with high relative humidity and little wind even in mild temperatures. The water of the emulsion must evaporate to achieve the total cohesion of the binder and if not, premature detachment of aggregates will occur, with the risk of having to re-execute and over-dosage. Another problem with cold is the formation of skin in the applied emulsion that retains the emulsion between the treatment and the base. This effect can seriously affect the treatment in the first days of heat, since the vapor pressure of the retained water pierces the membrane and begins to come to the surface, causing punctual exudations that can affect the rest of the treatment. To avoid these problems, see in the Book the "7.4.10 Execution in winter" that are used for those complicated days as well.

Aggregate penetration potential: The driving of the stone in a granular base can seriously affect the necessary voids of the system leading to exudation mainly in the tracks where the tires make an extra compaction effort. It is first necessary to evaluate this effect by means of the Ball Penetration Test (Annex D of the Book) and then take measures such as reprofiling and compacting or stabilizing with cement.

Component dosage: An excess of residual binder in the system is not perceived in the winter but as temperatures increase and its viscosity decreases, the voids are reduced both by expansion of the asphalt and by the accommodation of the aggregate that the binder allows. Here the variables to control are several, such as the theoretical design itself regarding what is found in the field, the calibration and periodic maintenance of the used equipment, the use of binders suitable for traffic and climate. For each of these variables you can find a detail in the Book of good practices.

Execution method: For double irrigations, it is necessary to evaluate if it is possible to do both irrigations on the same day and thus ensure that all the aggregate used is locked prior to the release of traffic. When irrigation A is carried out and much later B, it happens that the initial simple treatment settles down and becomes clogged, reducing its macrotexture as well as losing some aggregate and therefore the potential for exudation increases. When B is executed, the dosage should be adjusted to the new existing macrotexture, which does not happen, ending in exudations. The use of TMT technology allows double irrigations to be carried out on the same day, ensuring the success of the treatment. We have technology transfer licenses that include
know-how and technical assistance through a training course. For more information enter Licenses. https://bitafal.com.uy/licencias/

Used materials: Aggregates of the same size generate interlocked surfaces that better distribute traffic efforts, are more resistant to detachment and have less potential for exudate, for this reason we must adjust the sizes to consecutive sieves. Using 5-14 mm aggregates for example implies that physically first the 5 mm falls and then the 14 mm, leaving the latter not adhered to the surface and changing the aggregate / asphalt balance.

On the other hand, the emulsions must have an adequate residual binder, with sufficient viscoelasticity to prevent bleeding in the summer. In addition, it must be of the appropriate degree of modification for the traffic and climate of each particular work. line emulsions On the other hand, the emulsions must have an adequate residual binder, with sufficient viscoelasticity to prevent bleeding in the summer.

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.
