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.
