GRUPO BITAFAL'S FIRST CYCLE OF WEBINARS FINISHED WITH GREAT SUCCESS

During September, October and November, the first cycle of Webinars was held, in which topics related to High-performance Surface Treatments were developed.

Throughout the cycle we delve into the content found in our book that bears this name and what is available to download on our website: https://bitafal.com.uy/libro-tratamientos-superficiales/

The cycle consisted of 3 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.

The recordings are already available on our website. They can access them HERE

Thanks to the more than 450 users who followed us throughout the cycle, and to convey to them that this was the beginning of a new modality that we will begin to implement.

As always, we are open to your concerns regarding the topics that are of interest to you so that we can develop in future webinars.

We go for more, we will continue to share paths.

Module 3 - Webinar Surface Treatments

This was the third and last module of the Webinars cycle. In this instance, the theme of Irrigation with gravel was developed: the most efficient option for conservation.

The role of surface treatments in pavement management was studied in depth.
We had the presence of Jorge Prozzi, Professor at the University of Texas at Austin, who told us, among other things, about his research in this area.

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.

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!

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.
