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.

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.

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.

Micro cold in Route 10

With the advent of spring various surface treatments works resume

By adjusting the conditions of implementation for Capeseal Route 60, Serviam has made several test sections Route 10, where the equipment for micro-agglomerates cold, Romanelli UHR 900 E-FLOW, has a very good performance and high performance in work.

Tests were conducted near the oil Boya, on the old pavement of Route 10 and on a simple treatment of stabilized done before winter.

Quality results are obvious, the mixture homogeneity achieved, excellent surface texture and rejuvenation of old pavements for the next summer season.

Although conditions were pretty wet day without sun, Micro emulsion 62 P25 BITAFLEX He performed well, achieving full coverage of the aggregate mixture fluency and cutting within a reasonable traffic for release at the end of the day time.

We leave you some pictures of the experience.
