ARMOURBAND

ARMOURBAND

A stress absorbing overbanding system for sealing reflective cracks in asphalt and concrete

pavements. In service the system offers high tensile strength without bleeding or

deformation under vehicle movements.

DESCRIPTION

A polymer modified bituminous compound containing fibre reinforcement, aggregates and

adhesion agents which resists deformation and has the strength and flexibility to limit the

re-occurrence of cracking.

PHYSICAL PROPERTIES

Minimum Application Temperature: + 3°C

Product Pouring Temperature: 170 ± 10°C

Maximum Safe Heating Temperature: 190°C

Penetration Value BS2499:1993 20 ± 10 dmm

Flow Resistance BS2499:1993 < 3mm

Softening Point BS2499:1993 100 ± 15°C

Flash Point COC °C > 250°C

Specific Gravity 1.5 ± 0.05

CHEMICAL RESISTANCE

Bituminous products soften in contact with petroleum solvent and mineral oils. The product

has good resistance to dilute acids and alkalis.

STORAGE

Store in a cool dry place preferably under cover and away from direct sunlight.

PACKAGING

Silicone or Poly-silicone lined sacks - 25Kgs Net.

SURFACE PREPARATION

The surface should be thoroughly cleaned and dried using a hot compressed air lance

operating at 800 - 1000°C to remove any dust, laitance and loose foreign matter.

ARMOURBAND

APPLICATION

The material shall be loaded into a preheating mixer fitted with positive temperature control

and mechanical agitation and raised to it’s application temperature of 190 ± 10°C.

Apply the material using a screed box with a suitably designed trailing edge to give an

applied thickness 3/4mm and a with in accordance with HA guidelines.

On an average textured surface, the spread rate for ARMOURBAND is approximately

180m²per metric tonne.

SAFE HANDLING PRECAUTIONS:

* Do not exceed the maximum safe heating temperature.

* Do not allow the hot material to come into contact with

water as the product will react violently.

* Always wear the recommended protective clothing - see below.

ARMOURBAND presents no acute health hazard at ambient temperature. However, as

these materials are normally handled at elevated temperatures when their physical state

changes to a liquid, the bitumens present in these products give of fumes which are

undesirable to inhale as very small quantities of HYDROGEN SULPHIDE may be present

in the bitumen.

RECOMMENDED PROTECTIVE CLOTHING:

Overalls, Goggles/Visor and Closed Safety Boots when handling hot product.
