BAUMA 2019

The biggest event of the construction broke records of participation and exhibitors.

For the third consecutive year BITAFAL group traveled to the city of Munich to participate BAUMA. This event, held every three years, was the biggest in its history and where more than 3700 companies presented their products and services. During the 7 days of the fair, from 8 to 14 April, 620,000 visitors came from 200 countries to learn about the latest advances in technology in both civil construction and road.

This time, the fairgrounds, opened new areas reaching 614,000 m2 of exhibition, fair really an eyesore.

From Uruguay several technicians and businessmen were present to meet new products and to incorporate these technologies in our country. We can proudly assure how many construction equipment companies mention Uruguay as a benchmark in innovation and incorporation of the latest trends in equipment and techniques. This is thanks to the joint work that many of the actors in the road family have been doing in recent years.

The world's leading trade fair for construction machinery, building materials machinery, mining machines, construction vehicles and construction equipment, generated the best results in the exhibition's 65-year history. The number of visitors increased by around 40,000 over the total for the previous event in 2016. More than 250,000 visitors came from countries outside of Germany. The top 10 visiting countries after Germany were: Austria, Italy, Switzerland, France, the Netherlands, Russia, Sweden, the Czech Republic, Poland and Great Britain. The fair also saw a strong increase in the attendance of foreign visitors. China, Australia and Japan made significant gains in this group.

The most impressive stands were again the Liebherr, Caterpillar and Wirtgen. These exhibitors have whole sheds or buildings built exclusively for the fair, with exhibition equipment, meeting rooms, restaurants and shows to showcase the latest innovations.

Overall trends in this latest edition were hybrid engines for construction equipment, the 4.0 generation equipment, wireless technology for many applications and automated almost completely equipment.

Another interesting experience is the virtual reality that is being used for operator training and for different applications such as security awareness at work or even see the finished project from within.

The next edition will be held from 4 to 10 April 2022 at Messe München also in the beautiful city of Munich.

RECYCLED CEMENT AND TMT ROUTE 15

Molinsur trust GROUP BITAFAL for the implementation of technical TMT on recycled with cement made in Route 15.

Adjusted dosing and construction conditions, has been developed excellently recycled TMD on cement. The combination of these two techniques provide a unique opportunity to build synergy routes in our country.

Recycling Portland cement is carried out very rapidly on which an emulsion is applied IRRIGATION BITAFLEX 65 P25 with sand as curing irrigation. TMD is then applied with 14 to 19 mm and gravillín stone 2-6 mm with posterior irrigation fog, all run on the same day and with the same emulsion BITAFLEX IRRIGATION 65 P25.

The surface quality of TMT shows great cohesion of the whole package, without loss of aggregates and large voids content serve several functions. For one drain water towards the shoulders reducing the "Spray" effect and leaving a proportion of feasible to be filled by binder and thus prevent any errors dose or overlap that can result in air exudates.

The results are already more than validated on Route 15 in other sections own previously executed. It is expected durability of these jobs that we hope will be adopted by more manufacturers in the short term.

NEW TECHNIQUE FOR CEMENT CRACKING CONTROL

Serviam has developed an interesting team to prefisurado recycled with cement.

Drawbacks consabidos generating shrinkage cracks of cemented materials are subject to attack because they can reduce the life of the pavement by water ingress. Usually in our country it has incorporated the technique with a heavy microcracking to mitigate these effects but there are other alternatives globally with specific equipment Compactor.

Serviam company developed a computer adapted to perform a Bobcat injecting the emulsion prefisurado IRRIGATION BITAFAL 65 at a depth of 20 cm each 4 m crosswise.

After initial compaction of the recycled material prefisurado this is done then continue working, leveling and final compaction. Of note is the use of technology to achieve grade project controlled by RF motoniveladora.

Subsequently curing the same emulsion BITAFAL IRRIGATION 65 is performed with quarry dust is released and traffic. By far the results are very good and it shows on the go using technology to control IRI. In the next few weeks they will be starting tasks paving asphalt hot mix in 5 cm surface layer.

We will see the behavior of this technique prefisurado in the future. For now, in every induced cracking and the asphalt it is necessary to prevent water ingress so hopefully a lifetime of work done.

The equipment developed by Serviam has a storage tank emulsion, a positive displacement pump, a wedge (shark fin type) of 25 cm which leaves a pipe 20 cm and a solenoid valve for controlling the dosage from Bobcat.

The fin makes a wedge about 2 cm wide in advancing the equipment is filled with emulsion BITAFAL IRRIGATION 65. Then the material of the side itself closes the wedge and leveling and compaction are performed normally. It can be seen watering cured, made with 1L / m2 of IRRIGATION 65 and 6 L / m2 of dust, marks prefisurado every 4 m in the photos below.

RECYCLING AND CAPESEAL ROUTE 60

The works mentioned in previous bulletins (Bulletin # 98 NOTE: Capeseal on Route 60) Have come to an end and the result is really very good.

The recycling works Portland cement and the Capeseal provided as wearing course have culminated in this work quality that carried out Serviam. Aesthetic and functional completion of the section is excellent and we recommend those not familiar with the technique of Capeseal visit the section from Sugarloaf to the city of Minas.

It is for the group BITAFAL proud to have been involved in the whole process, from the dissemination of the aforementioned techniques in lectures, conferences and in our book "High Performance Surface treatments"To see it come true with the quality achieved. Thank provided Serviam confidence in our products and services in each of the construction phases of the stretch.

UNIFORMITY AND QUALITY

Asphalts new terminal opened last October (Bulletin # 98) It allows great homogeneity of asphalts basis for the manufacture of emulsions and modified asphalts.

With these investments and operational changes in plant we are achieving consistent quality of our products. The new terminal allows we to emulsify asphalt batch of some 320 tons each that are constants in quality and consistency batch after batch of emulsion.

With asphalts available in Uruguay (AC30 and 150/200) we achieved a "Blend" that meets the requirements for emulsions classified by performance for our country exceeding 61 ° C in Grade Performance testing AASHTO M320 to prevent exudates in time summer.

Since November 2018 penetrations waste our emulsions for surface treatments are between 60 and 70 dmm and softening points above 50 ° C constant and predictable. We have also improved the quality of viscosities and emulsion to standardize the process of emulsification and the size of the stocks of finished product.

Today as never before BITAFAL has full confidence in the superior quality of its emulsions over other emulsions present in the local and regional market.

After liberation of the base to emulsify BLEND, ensuring PG having a suitable batch emulsion between 30 and 90 tons are performed according to the type of emulsion. We have duplicates for each type of emulsion allowing us to quietly release the batch laboratory prior to loading tanks.

The new tanks have agitators and load filters to remove any impurity or cream that may arise.

We have also implemented a system control content and temperature of all tanks of the plant that allows us to accurately adjust stocks and forecast production and delivery.

Laboratory incorporated a dynamic shear rheometer (DSR) and a large battery of additional tests to determine the quality of emulsions, not only as specified in the tender documents and the IRAM 6698 but for new global trends.

We have a stereo microscope to see the quality of emulsification and micelle performance level.

We are moving the way for emulsions level of performance (EPG) which will be the specifications of the future.

These great efforts are BITAFAL we have a commitment to national roads and we want things done right because that is our responsibility.

VEDA IN Surface treatments

With the imminent entry of autumn, we should take the necessary precautions in the execution of surface treatments.

The ban begins in a few days and the most suitable for our summer climate emulsions begin to generate low yields in the execution by the cold and the few hours of insolation that we are already living.

Asphalts specifications based emulsions remain unchanged throughout the year. If the manufacturer wants a change in specifications to continue the work, we do get an email with the desired specification.

We recall that in remitos load the batch number corresponding detailed, and which can enter our website to have the Quality report and to corroborate with the requested specifications.

To maintain the quality of the works must run less meters per day before releasing traffic with some specific recommendations always looking to reduce the amount of water in the system.

We invite you to know in detail the recommendations on the following link "SEVEN RECOMMENDATIONS FOR USE OF EMULSIONS IN WINTER"

surface treatments:

1) heating the emulsion to be used above 70 ° C to promote evaporation of water from the emulsion itself.

2) Do not wet aggregates and try to use the top in the collection that are drier and drained, not load the gathering at the bottom.

3) Start the task early in the morning, regardless of the prevailing temperature, for that tranche has executed the most hours of exposure to air, wind and sun.

4) Apply TMT technologiesThat favor locking of aggregates applied, achieving superior quality and finish.

5) Have properly calibrated equipment graveled and irrigation to the quality objective is sought to be achieved.

Irrigations primer:

In these autumn and winter periods irrigation primer they are affected by the high rate of humidity in the foundations.

It must be respected as well as primers with dilute MC 1, optimum moisture application for the purpose of achieving a successful work.

By the above, it is normal for a primer in summer takes less than 1 hour in winter takes more than 24 hours to get to be acceptable.

Soil stabilization:

It is best suited to perform soil stabilization with cement or lime period.

Water needs hydration are very basic and profiling work, compaction and sealing are unmatched.

Here the sealing emulsion IRRIGATION BITAFAL 65 at 1 per square meter lt should be complemented with a sealed with quarry dust good quality.

These bases have such successful results supporting several months before recommencing graveled tasks in appropriate months.

It IS NOT WHAT THEY SAY ...

During February we conducted two tours of much of the country to see how surface treatments behaved during the summer.

After having traveled more than 2800 km were able to verify that the problems of exudation that both resonated in the press and in the environment, are actually a small part of what has been done in recent months across the country.

We could risk to quantify the problem areas and we do not exceed 2 or 3% of total executed.

Exudation is fully controlled and are the result of a sum of different errors, based not only attributable to asphalt emulsions. We have traveled sections executed with national emulsions, RC2 or imported emulsions, and in all cases there exudates sections. A common denominator of most of them is running during the winter without the necessary precautions.

The emulsions BITAFAL ALWAYS comply with the current specification DNV which includes a penetration range of 50 to 200 dmm and we subdivide into soft, medium and hard to adjust to the realities of each work.

Every summer we adjusted basis or hard asphalts media but from now on is the quality of asphalt base will maintain throughout the year. Only order will manufacture soft asphalt emulsions that way unless there is a variable in the appearance of exudates.

You can read some recommendations to reduce the appearance of exudates below:

To prevent exudates is essential to work in good weather conditions to ensure proper curing of the emulsion without risk of premature detachment and redo work force overdosing asphalt.

If you have to work during the closure take the precautions mentioned in note below.

Other factors are very soft exudation base surface allowing penetration of the aggregate A treatment and reducing the proportion of several necessary. The same applies to well-graded aggregates that fill the gaps for the asphalt emulsion.

The lack of a suitable dosage criteria, use the same "recipes" for all treatments running and lack of calibration of equipment are key components for the job fails.

Aggregates with high dust content are also a problem because the reduced active adhesion usually increase the dosage asphalt irrespective of subsequent consequences.

Must professionalize dosage calibration, the release of the basis for treatments and especially the aggregates used.

Treatment well executed, even with soft emulsions, may not have bleeding problems ... and many kilometers executed last winter with soft emulsions which did not have problems when they reached the heats.

Last December 12 took place in the vicinity of Route 8 to Route 82 the opening of the recent doubling of Route 8 and Route 11 between Pando by COLIER S.A.

They were 30 months of effort by the company to achieve the stated objective of doubling the route, make a new bridge and an upper passage and meet the highest standards of road safety.

14 km were retreads with modified asphalt BITAFLEX AM3, que le brindarán al tramo construido una gran durabilidad frente a las cargas que por allí circulan. Agradecemos a la empresa por confiar en Grupo BITAFAL el suministro del asfalto modificado para tan importante obra.

The inauguration was attended by the Minister of Transportation, Victor Rossi, the Minister of Labor, Ernesto Murro, the Mayor of Canelones, Yamandú Orsi, high-ranking national and departmental authorities, members of colleague companies, the MTOP, suppliers and residents of the area. During it, Hebert González was honored and remembered with anecdotes, phrases and emphasizing the capacity for work and love for what is done, which were the identity of the recently deceased director of the company. Later, Colier's direction through Eng. Juan Echeverz paid tribute to the "patron" and friend that filled all those present who were lucky enough to meet him with emotion.

Work on Route 8, Juan Antonio Lavalleja, consist of: the construction of two new traffic lanes 3.6 meters wide each, with an inner shoulder of one meter and two meters outside. Also, a bridge over the Pando stream, with a length of 166 meters, with 9.2 of road width plus a cycle track, and a railway underpass in Splice Olmos 22 meters long was constructed. The tasks required an investment of 52 million dollars.
