2. About Us
MERCO was establish in the Kingdom of Bahrain in the year 2004
under the patronage of H.H. Shaikh Khalifa Bin Hamad Bin Isa Al-Khalifa.
MERCO is the biggest Bitumen cut-back manufacturing facility in the
Kingdom of Bahrain. Our state-of-the-art PLC controlled system help us to
manufacture products to highest degree of accuracy. We have in-house
quality control to serve our Clients better.
Our materials are packed in Drums, Flexi tanks and 1-Ton bags as per the
requirements and needs of our Customers. Our special packaging facility
is designed to lower the temperature of material before loading in Flexi
bags.
MERCO is also into processing of Petrochemicals from SABIC for in-
ternal use. MERCO also provide services like Plant maintenance, Oil
Storage, Material Packing, Tank Cleaning and Oil Recycling throughout the
world.

6. Bitumen and Product Specifications
Bitumen is available in a variety of grades. Specifications vary to meet
the needs of the consuming industries and are based on a series of physical
tests that define the safety, solubility, physical properties and durability of
bitumen.
The physical properties are designed to define performance character-
istics that are required under the climatic and loading conditions that the
bitumen will experience in service.
Bitumen is graded according to the standardized testing methods. These
tests also give rise to two commonly used terms which describe the method
of measurement, rather than a “type“ of Bitumen.

7. Penetration Graded Bitumen
Bitumen is classified by the depth to which a standard needle will pene-
trate under specified test conditions.
This “pen” test classification is used to indicate the hardness of bitumen,
lower penetration indicating harder bitumen.
Specifications for penetration graded bitumen’s normally state the pene-
tration range for a grade, e.g. 50/70.
Other tests are used to classify the bitumen for specification purposes,
such as softening point, solubility, flash point etc.

8. Cutback Bitumen
Cutbacks are bitumen preparations in which the viscosity of the
binder has been reduced by the addition of a volatile solvent, nor-
mally derived from petroleum.
Cutback products are typically used for spraying and some mix-
ing applications. The advantage of cutbacks over emulsions is
much higher residual bitumen content, typically over 80% com-
pared with over 40-65% for Bitumen emulsions.
The result is more Bitumen left on the roadway after curing, for
the same volume of binder applied.

9. Fluxed Bitumen
Fluxed bitumen’s are bitumen preparations where the viscos-
ity of the binder has been reduced by the addition of relatively
non-volatile oils. Typical fluxants include gas oil and vegetable
based oils.
MERCO fluxed bitumen is prepared from Bitumen 60/70 grade,
fluxed with non volatile light fuel oil.

11. Bitumen Emulsion K1-40
Bitumen emulsion consists of three basic ingredients: bitumen,
water, and an emulsifying agent.
Based on specifications it may contain other additives, such as sta-
bilizers, coating improver, anti-strips, or break control agents. It is
well known that water and asphalt will not mix, except under care-
fully controlled conditions using highly specialized equipment and
chemical additives.
