in: Modified asphalt,Bitaflex AM3,Bitafal group,News

Flywheels Association of Uruguay (Auvo) BITAFAL Group relied on for supplying the modified asphalt AM3 being used as surface layer in the recent remodeling Speedway Victor Borrat Fabini El Pinar.

After several years it has been able to realize this dream that has had the support of several national companies and a very large effort by the Auvo policy.

Bitafal: new technologies to improve Caminería

The original work on Auvo, consisting in shaping the subgrade delivered, laying and compaction of ballast (this customer supplied) and the execution of a road surface 7cm thick with modified asphalt. Due to the high demands on surface finish is executed variant that is offered.

Soil movement, was conducted by Domingo De Vitta, with sand instead. Then after some adjustment of the executive project, we proceeded to the laying and compaction of granular material. It came from Cantera Casil of La Paz, supplied by the customer as mentioned.

With respect to the particle size in the first layer it wore its 12% natural sand with 5-14mm starting stone powder crushing Quarries Montevideo, with a percentage of 5.2% asphalt. The it wearing however, was performed without natural aggregates and with the addition of 1% lime. The optimum asphalt AM3 stood at 5.4%

The company had acquired a sonic level and another to copy the granular base which was carefully completed and controlled. The fit with soil and planted the seed back will be at 4.00 meters wide and around the inside of the loop with some minor requirement to prevent sand entering the track.

We congratulate everyone involved for the great work done.

JOINTS IN NEW BRIDGES TACUAREMBÓ

The Saceem-Cujo consortium has relied on the Bitafal Group in the supply and installation of anchored neoprene seals new suspension bridges that were built in Paso del Bote in the city of Tacuarembó.

The construction of two new bridges were made with existing (dating from 1930) in the Laguna de las Lavanderas where Patria Gaucha is performed. They consist of reinforced concrete arches 60 m span and 12m high guyed by a rigid board.

To withstand the intense movements, SC-160 type joints were installed in the stirrups and SC-230 in the central stack. These boards are designed for maximum movement of 160 and 230 mm. In addition maintenance of existing bridges which were installed together type SC-42 they were performed.

The consortium has also relied on our company for waterproofing membrane RUBERSAM board as we reported in our previous newsletter.

The two new bridges 60 m and 120 m long on Arroyo Tacuarembó have a road width of 8 m and a path 2.5m complement existing bridges, traffic circulating dual carriageway in one direction on themselves.

RUBERSAM STEP IN BRIDGE OVER THE BOAT - TACUAREMBO

Bitafal Rentals He has ventured into a novel technique for the country in the waterproofing of bridge decks.

The SACEEM and José Cujo S.A. companies They relied on the Bitafal group for performing the first waterproofing membrane type and relieving stress RUBERSAM on national bridges.

It consists in applying an emulsion Bitaflex Riego 65 P40 with hard asphalt residue washed and classified with stone. With this waterproof membrane is achieved in all the boards of the bridges and is a suitable surface for adhesion of the asphalt intended as overweight.

The work consists of two new bridges and rehabilitation of existing ones on Paso del Bote, in the city of Tacuarembó. The same is in final stages of construction and is expected inaugurarlos before year-end.

The application process of the RUBERSAM membrane was performed as follows:

* Clean the surface of the board by, sweeper, blower and pressure washer.

* Application synchronized by double automatic spreaders an emulsion layer Bitaflex Irrigation 65 P40 with hard asphalt residue washed with stone and classified.

* Trabado stone matrix generated by light Compactor tandem.

* Application irrigation fog with the same emulsion Bitaflex Riego 65 P40

The total dosages envisaged emulsion was 2.5 L / m2 and washed with 14-19 mm sized stone at 12 L / m2.

ASPHALT TECHNICAL WORKSHOP 7th.

Monday July 4 took place in the Crystal Tower Hotel Montevideo 7th Asphalt Technical Seminar organized by the Uruguayan Association of Roads in conjunction with the Standing Committee of Asphalt Argentina. It was attended by nearly 110 national road technicians who listened and participated in conferences exhibitors from Uruguay, Argentina and Chile.

The talks were on current issues of technology paving Uruguay from the use of Capeseal, the bitumen stabilized materials as those used in Route 3, to the performance of thin asphalt mixes F10 type, such as that in Ruta Interbalnearia recently.

Mr. Paternostro began with “Cape Seal: General concepts, national specifications and local examples” showing the results of the first sections carried out in Uruguay, both in its good macro-texture and in its impermeability, as well as the specifications currently used. Then, Dr. Ing. Fernando Martínez (Argentina) from IMAE presented "Prediction models of the rheological properties of asphalt binders", in which empirical tests such as penetration, softening point and Brookfield viscosity are used to predict rheological properties of asphalt binders. asphalts quite tightly without the need to use an expensive rheometer (DSR).

Eng. Rosana Marcozzi and Dr. Francisco Morea (Argentina) from LEMIT presented us with “Experiences in Argentina with warm asphalt mix technologies. New tests applied to the characterization of its performance ”, showing the good behavior of this type of mixture in the experiences carried out and opening the debate on its application at the regional level. In Uruguay, only one section was completed in 2012 but we are working from BITAFAL to repeat the experience and draw better conclusions.

During the afternoon Ing. Germán Bavdaz (Argentina) told us about the "evolution of physical parameters of asphalt mixtures after 14 years of service", focused on the performance of such thin mixtures F10 on the Autopista del Oeste, one of the busiest in Argentina.

For closing Eng. Joaquim Kemp (Germany) made an interesting presentation on "BSM -Materials bitumen stabilized. Current state of technology ", a technology that is already being implemented in Route 3 and has a very promising future in Uruguay.

SEVEN RECOMMENDATIONS FOR USE OF EMULSIONS IN WINTER

21 June 2016
in: Emulsion,modified emulsions,Bitafal group,winter,News,technology

When they start to shorten the days and appear the first cold start problems with the use of emulsions. This situation is repeated year after year and often turns into a spiral of construction problems that last for months if the corresponding precautions are not taken.

Being a recurring theme which we have learned to solve these years, we bring our 7 recommendations regarding the selection of products and ways of implementation to work in cold weather conditions.

While asphaltic emulsions have minimal restrictions on use in winter, since moisture of the aggregate is not counterproductive, if it is imperative that the embodiment in winter is different from the traditional, to avoid problems of detachment during execution and prevent exudates which cause in the first warm days of spring and every year we complained.

Las emulsiones catiónicas cortan por desbalance de cargas eléctricas y no es selectivo de verano o invierno, así que SIEMPRE cortan. Luego del corte existen diversos procesos dentro de la emulsión como coalescencia y curado, en el cual el agua de la emulsión debe evaporar para lograr la cohesión necesaria del asfalto residual con la piedra y así evitar desprendimientos prematuros.

Said above it is evident that the moisture retained in the system due to the low evaporation during winter, the aggregate / asphalt affinity is less. Subject usually solved from the viewpoint of performance as long as the maximum temperatures are above 10 ° C, otherwise it is not advisable to use emulsions until maximal exceed that temperature.

1) IMPROVE THE RESISTANCE OF THE MATRIX OF ARIDAchieve the stone is held in place by mechanical locking means.

When working on granular bases, use a heavy cylinder for driving the aggregate in the base and thus prevent detachment traffic. These solutions have drawbacks because if the stone is not large enough gaps may be affected and when summer comes the binder has nowhere to expand and asphalt appears on the surface. But if you plan to make a second irrigation or sealed future.

* If simple treatment, can be made the same in two passes with half the components in each pass, making the initial half containing emulsion below and above and the second irrigation achieved get into the gaps of the first giving a stone matrix closed using a heavy compactor.

* In case of a double treatment, perform the two executions on the same day to achieve the same closed die from the outset.

2) START very early: You must run risks in the winter mornings, once that blunts the sun. Recall that the emulsions cut by decompensation loads and we need all available hours of evaporation.

3) terminate PAST PERFORMANCE NOON: Watering must be discontinued after noon for a time sufficient evaporation in the last application so that when night came, the system achieves sufficient to withstand uncontrolled traffic cohesion.

4) heat more EMULSIONS: Si el problema es el agua retenida en el sistema luego del corte, podemos ayudar al proceso de curado si calentamos la emulsión entre 80 y 95°C para que el agua evapore mas rápidamente. Con las actuales emulsiones de RIEGO de BITAFAL no hay inconvenientes de escurrimiento debido a las altas viscosidades de las mismas incluso a temperaturas de 95°C. Además al ser en base a agua no existen riegos de incendio o explosión como si existe con el uso de diluidos.

5) AVOID AGGREGATES DIRTY: This recommendation is for all types of surface treatment but when the weather is good, you can moisten a dirty arid for the emulsion works well. That is not the case in winter where we seek to reduce the amount of water in the middle. With a dirty arid the emulsion will only adhere to dust causing peeling even if it is fully cured. (Especially if it is very hot)

6) ENABLE TRAFFICKING AND CONTROLLED EARLY FORM: Controllably release traffic (maximum speed 30 km / h) once finished the compaction in the early hours of the afternoon. There if we need the air traffic for the purpose of purging the system drops of water released from the residual asphalt and aggregates collaborate to lock each watering done.

7) USE OF EMULSIONS SUITABLE TO SITUATION: SPECIAL BITAFAL ASFALTOS emulsions prepared with different hardnesses of the waste and with different degrees of modification. Please find attached our table recommendations by type of work to be done, the area of the country and the time of year.

LIMITATIONS these recommendations:

Although it is possible to work during cold periods we not recommend performing work during the winter if:

1) highest temperatures all day do not exceed 10 ° C.

2) monogranular Treatments applied on hard surfaces such as concrete or asphalt layers and where traffic speed is greater than 75 km / h.

3) Surface treatments applied on very soft bases without adequate granulometry, as silts the coast, where a burial arid irrigation A occurs, reducing gaps and subsequent exudation.

TECHNICAL CONFERENCE Asphalt Mixtures - COARCO -

The BITAFAL Group was present at the R & D Technical Conference on new asphalt mixtures by the company COARCO from Argentina. It was held at the plant in Moreno, Province of Buenos Aires, on 25 April. Uruguay took part members of MTOP and LATU and Argentina participated leaders of National and Provincial Roads Authority, representatives from various dealers and other suppliers from the nearby shore.

During the conference the latest equipment were both laboratory mix design and workmanship, laying and compaction. mixtures of high RAP, colored mixtures, mixtures of batching and until a new asphalt scented low level of VOC emissions used were developed.

The sessions began with a visit to the company's state-of-the-art laboratory, where they have invested in high-level equipment for research and development. To list some of the equipment, they have an ignition oven to determine asphalt content, a gyratory compactor for mix design, a Wheel Tracking Test according to the new European regulations with a plate compactor, a unit to determine the dynamic modulus of mixes and a 4 point fatigue team.
