Manufacture of Bitumen C240 From Turkey and Dubai-UAE

 

Description

C240 is a paving grade Bitumen manufactured to AS 2008 Table 2.2 and is suitable for standard sealing and lightly trafficked asphalt applications.

Bitumen C240 is generally used in paving surfaces and sealing cracks because of its superior resistance to adverse weather conditions and excellent adhesive properties. Bitumen C240 has higher viscosity compared to Bitumen C170 which enables it to be used in asphalt pavements in warmer climates where traffic volume is moderate.
The high viscosity of Class 240 bitumen contributes to the creation of robust and durable structures, as well as roadways, thereby safeguarding the integrity of these constructions. Its exceptional waterproofing properties and outstanding resistance to adverse climatic conditions make Class 240 bitumen a preferred choice in asphalt mixing and spraying applications..

Bitumen C240 Applications

C240 bitumen can be used for all standard spray sealing and lightly trafficked asphalt applications.

Asphalt recommendations

Mixing Temperature	Holding time at Mixing Temperature	Medium term storage temperature	Medium term storage time	Maximum safe handling temperature
140-165°C	14 days	130-150°C	30 days	175°C

Sealing recommendations

Spraying Temperature	Holding time at spraying temperature	Medium term storage temperature	Medium term storage time	Minimum pavement temperature
170-180°C	7 days	130-150°C	30 days	15°C

During sealing operations, it is normal practice to add cutter oil to the bitumen to reduce binder viscosity to a level at which effective wetting and adhesion of the cover aggregate can take place. The quantity of cutter oil added to the bitumen depends upon the pavement temperature, the daily traffic and the nominal size of the cover aggregate.

Basic cutting practice for Viva Bitumen C170 bitumen should be as follows:

Parts cutter per 100 parts bitumen measured at 15°C

Pavement Temperature (°C)	Traffic (veh/lane/day)	Nominal Aggregate Size: 10mm or greater	Nominal Aggregate Size: 7mm or less
15 to 20	low (<100) med (100 – 1500) high (>1500)	7-8 5-6 4	7-10 6-8 5-6
20 to 25	low med high	7-8 5-6 4	7-10 6-8 5-6
26 to 35	low med high	4-6 2-4 2-3	6-8 5-7 4-6
>36	all	0-2	0-3

Bitumen C240 Health & safety

Bitumen C240 is unlikely to present any significant health or safety hazard when properly used in the recommended application where good standards of industrial practice are maintained. Further guidance on Product Health and Safety is available on the relevant Material Safety Data Sheet.
