CBAA CAP ECOLÓGICO AB-22 It is an asphalt cement modified with ground tire rubber and other additives that, under special process conditions, present performance characteristics, such as:

• Reduced thermal sensitivity – High softening point;
• Resistance to repeated thermal and mechanical stresses – Elasticity;
• Better adhesion under the aggregate
• Aging resistance.

CBAA CAP ECOLÍGICO AB-22 presents superior performance and durability in paving services, reducing maintenance costs and levels of road accidents, being an effective solution in terms of cost / benefit in asphalt services, such as:

• Hot-Used Asphaltic Concrete (C.A.U.Q), for severe weather and traffic conditions on highways and urban roads;
• Discontinuous Asphalt Coatings (C.P.A. – Friction Porous Layer / S.M.A. – Stone Matrix Asphalt), increasing the safety and durability of the coating, reducing problems on rainy days (aquaplaning / water spray);
• Surface treatments and stress absorption membranes (S.A.M. / S.A.M.I.) increasing the adhesion and cohesion forces of the aggregate / binder pair, reducing the effects of traffic and climate on the asphalt coating.

CBAA CAP ECOLÓGICO AB-22 it can be damaged if heated to high temperatures (above 200°C) or after repeated or prolonged reheating. It is usually delivered in the machining temperature range (175°C – 190°C), and must be unloaded in tanks free of conventional asphalt ballast (CAP – 50/70 or CAP – 30/45)

It is recommended, during storage for a period longer than 5 days, to store the product at a milder temperature than usual (between 100°C and 120°C), being recommended for short periods of storage at a maximum of 165°C. Store at room temperature if product is to be stored for long periods (20 days or more).

The temperature throughout the tank must be uniform, and the heat distribution must occur homogeneously, through the use of a recirculation pump. Never heat the product directly, but in tanks equipped with a thermal fluid coil.

CBAA CAP ECOLÓGICO AB-22 it is classified according to the Brookfield rotational viscosity, according to the resolution of DNIT 111/2009 – EM:

CBAA CAP ECOLÓGICO AB-22 it is supplied in bulk, liquid (tons) in tank cars.

During handling, use PPE (Personal Protective Equipment). In the event of an accident, consult the Safety Data Sheet for Chemical Products (FISPQ – No. CBAA.013).

Do not perform asphalt paving services in environmental conditions with a temperature below 10°C, imminent rain during the course of the services or on surfaces with the presence of moisture.

CBAA CAP ECOLÓGICO AB-22 it is framed by the UN (3257) as a substance of risk 9 and subclass N.E (high temperature liquids)

As for the arrival of the product at the work site, the sample must be collected for the reception/quality tests.

The product must be kept in deposit (bulk), duly sealed, in lined tanks, with serpentine (thermal fluid steam) and circulation pumps.

The product in storage period (indefinite time) does not suffer degradation of its properties, as long as appropriate procedures are carried out, not being recommended overheating operations (>177°C), or maintenance of high temperature with successive reheating for prolonged period of storage .

In case of prolonged storage period, it is recommended to keep the asphalt temperature at 50°C/60°C or even room temperature, raising the temperature of the material for the asphalt mixture machining process.
