BITAFAL GROUP SAYS PRESENT AT THE 2020 SLURRY SYSTEMS WORKSHOP (# 2020SSWS)

From January 20 to 23, 2020, the largest annual grout and micro-pavement workshop in the United States was held in Las Vegas, organized by the International Slurry Surfacing Association (ISSA). More than 450 professionals and experts from the road sector discussed the importance of surface treatments, their laboratory design, and the best practices for execution and control of works.

Surface treatments in the United States represent only 5% of its road network, but that small number in a country of enormous dimensions allows it to become one of the world leaders in this technology. The # 2020SSWS delves into the use of gravel, micro agglomerates, grouts, crack sealing, Capeseals, ultra fine mixes, etc. and the combination of these to extend the life cycle of the pavements.

The workshop presents the technical knowledge of experts who comment on the details that must be taken into account in the laboratory and on site, with tips for correctly applying the guidelines developed by ISSA (A105 and A143). Among the topics discussed could be highlighted:

- Care and controls in the laboratory to improve the design of micro-agglomerates.

- The physical and chemical foundations of the breaking and curing of special micro emulsions.

- The importance of fissure sealing to extend future treatments.

- Best construction practices for high-quality grouts and micro-agglomerates.

- Use of RAP in preservation techniques, among others.

In addition, the practical application of these foundations was carried out, carrying out small material testing sessions to determine the optimal mixing time in the laboratory and later real test sections with machines and complete work equipment.

Finally the online tool was presented to www.roadresource.org for the correct selection of the type of treatment with calculators to determine life cycle costs, annualized equivalent costs, remaining life and cost benefit. The goal of ISSA with this excellent website is to promote the selection of the right treatment, on the right path, at the right time ("The Right Treatment on the Right Road at the Right Time").

ADVANCES IN ROUTE 14

Road Circuit 3 advances according to the schedule foreseen in the rehabilitation of Route 14.

The “Circuit 3” Public-Private Participation project in charge of the COPASA and ESPINA consortium comprises the sections of Route 14 that go from the city of Mercedes to Sarandí del Yí. There are about 300 km of road rehabilitation using cold recycling technology with Portland cement and a subsequent 4 cm tread with the new modified asphalt BITAFLEX PG 70-28 provided by Grupo Bitafal.

In addition, the construction of a bypass to the city of Sarandí del Yí, the construction of two new traffic lanes in the city of Trinidad and the construction of a new section that connects Route 14 with Route 3 is planned.

This Route that crosses our country practically in the center has an important weight for the productive activity, foreign trade and the productivity of the companies that export through the port of Nuevo Palmira and especially for the pulp production plants of UPM and Montes del Plata. The situation of the same was diverse, sections in bituminous treatment and sections in asphalt layer with variable widths in all their extension.

The new project involves a widening in several sections together with their respective bridges, correction of the layout, planimetric improvements to increase the average speed as well as reinforcement of the structure and a smooth and safe running surface.

Currently there is a large deployment of teams and work fronts throughout the route. Many national companies are doing a great job in the construction of their respective sections or bridges. Idalar, Cujó, Incoci, Díaz Alvarez, Molinsur, CVC, Frivial, Saceem, Espina and other subcontractors are working at the same Impact.

All sections have a widening and recharging front for granular material, then a 20 cm cold recycling front with Portland, then an emulsion curing irrigation IRRIGATION BITAFAL 65 and gravel and finally a paving front applying a 4 cm thick asphalt mix with modified asphalt BITAFLEX PG 70-28.

In Bulletin # 108 of last November we anticipated some aspects of the work such as the incorporation of technology for example: 4 m rules for pavers, automatic control systems for motor graders, oscillating compactor rollers, among others, as well as safety and neatness of the works.

In addition to this, the works are being carried out at a very good pace and it is expected that by the middle of this year a large part of the sections will be completed.

Once again, we thank the Consortium and the contracting companies for the trust they have given to supply such an important input as modified asphalt and emulsions for a road work of such magnitude.

EFFICIENCY IN TREATMENTS BITUMINOSOS

Once again, the Colier company entrusted us to collaborate in the surface treatments that are being carried out on Route 7 at the height of Santa Clara de Olimar

Bitafal Rentals made available to the company a double ACMAR spreader of French origin that has the characteristic of being a graveller with telescopic rollers, which allows a perfect dosage of the calibrated aggregates as well as the necessary emulsion in a fair and precise way.
Through this technology, the company went from having a crew for the execution of the treatment of about 8 people to only 3. In addition, the advantage that the same equipment doses emulsion and aggregate allows greater control of the dosage and better results in the treatment built.

We present ourselves on site and agree, using a calibrating drawer, the appropriate dose of aggregate and after defining this characteristic, the necessary emulsion. The results are eloquent and the doses and emulsion / aggregate ratio are behaving in a superior way without the risks of overdosing so harmful for subsequent exudations.

Bitafal is already in the operational phase of track tests of a series of new asphalts for winter use that are applied hot and with automatic release to traffic. This project is linked to a new generation of developments that we have been working on for 3 years in order to ensure that our market does not see its productivity altered during closed seasons.

Our companies are going through a very difficult time economically linked to the low productivity of execution of works. When Bitafal incorporated the first recycling train, it achieved a great leap in productivity on the road and now we are preparing for this new generation of very high performance elastomeric asphalts that will complement this innovation.
