Oxidised Grade Bitumen (115/15) complying with BS EN 13304:2009 for Industrial applications
 

A range of PG grade binders complying with AASHTO M320 are available, selection of which depends on climatic variation in different countries.

CYTECH has the expertise and know-how from many years of international supply using a variety of bitumen sources with different binder modifiers including polymers when appropriate to achieve the required properties.

For cooler climates e.g. New Zealand, Cyrus Infrastructure would supply PG 64-16 whereas for the Middle East region, PG 76-22 has typically been supplied.

CYTECH International has unparalleled experience across the Middle East region complying to different specifications for PMB asphalt binders on major infrastructure projects with special focus on binder performance in the Middle East climate e.g. Abu Dhabi (PG 82-22) and Doha (PG 76-22 / PG 76-1 OE) International Airports. CYTECH can supply PMB to any of the following standard specifications:

AASHTO M320 using state-of-art hybrid polymer technology

AASHTO M332-14 using hybrid polymer technology to meet the full range of PMB asphalt binders graded by performance, using the multiple stress creep recovery (MSCR) test. Grading designations are related to the average seven-day maximum pavement design temperature, minimum pavement design temperature, and traffic loading. This specification incorporates T 350 for determining non-recoverable creep compliance, Jnr. "S," "H," "V," or "E" designations are specified for standard, high, very high, or extremely high traffic loading, respectively.

EN 14023 using elastomeric hybrid binders designed to suit climatic conditions and complying with the European Specification Framework for PMB.

SPECIAL 'PMB' grades which are bespoke polymer modified bitumen grades designed to meet project specific requirements.

All types of rapid to slow setting bitumen emulsion both anionic and cationic are manufactured in compliance with the following Standard Specifications:

ASTM D977-13 and AASHTO M140 for all ANIONIC Emulsified bitumen for pavement construction.

BS 434-1 :2011 Bitumen road emulsions Part 1 - Specification for ANIONIC bitumen road emulsions e.g. K1-40 and K1-60. (These grades are still specified for use on some contracts but please note this specification applies only to anionic emulsion. BS 434-2:2006 Specification for Cationic bitumen emulsions has been withdrawn and is replaced in Europe by BS EN 13808:2013 Framework for specifying Cationic bitumen emulsions).

ASTM D2397M-13 and AASHTO M208 for all CATIONIC Emulsified bitumen for pavement construction.

Available in 25MT Bulk road tanker, 1 MT IBC, 200L Drums.
