Hot bitumen flowing from a channel into a trough

Bitumen 60/70

Penetration grade

The harder standard grade for hot climates and heavy traffic loads.

The designation gives the penetration range: a standardised needle penetrates between 60 and 70 tenths of a millimetre at 25 °C. The smaller the value, the harder the binder. In hot regions and on heavily loaded roads the harder grade prevents rutting, because it yields less at summer temperatures.

Standards and approvals: ASTM D946 · EN 12591
Applications: Road construction in hot climates · Asphalt mixing plants · Heavily loaded carriageways
Packaging: Bulk (heated road tanker) · 208 L drum · Poly bag / jumbo bag
Regions of origin: Middle East · Iran · Southeast Asia
HS code: 2713.20
Supply: On a contract basis

Typical values Bitumen 60/70 · Penetration grade
Property	Unit	Value	Test method
Penetration at 25 °C	0.1 mm	60 to 70	ASTM D5
Softening point (ring and ball)	°C	49 to 56	ASTM D36

Typical values, not a specification commitment. The batch analysis (COA) is binding.

Bitumen 80/100

Penetration grade

The softer grade for cooler climates and more flexible surface courses.

With a penetration of 80 to 100 tenths of a millimetre this grade is softer and stays more elastic at low temperatures. That reduces cold cracking in temperate and cool regions. The softening point is correspondingly lower than for 60/70.

Standards and approvals: ASTM D946 · EN 12591
Applications: Road construction in temperate climates · Asphalt mixing plants · Structural waterproofing
Packaging: Bulk (heated road tanker) · 208 L drum · Poly bag / jumbo bag

Polymer modified bitumen

PMB · Performance Grade

Binder upgraded with elastomers for heavy traffic, bridges and airports.

Adding polymers, usually SBS, widens the temperature range in which the binder works. It stays stable in summer and elastic in winter. The Performance Grade classification states this range with its upper and lower limit and therefore says more than penetration alone.

Standards and approvals: AASHTO M320 (Performance Grade) · EN 14023
Applications: Motorways · Bridge decks · Airport taxiways · Heavy duty surfaces
Packaging: Bulk (heated road tanker) · 208 L drum
HS code: 2713.20

Bitumen emulsion

cationic, rapid setting to slow setting

Water based binder for cold applications without heating.

In an emulsion the bitumen is present as fine droplets in water and can therefore be processed at ambient temperature. After application the emulsion breaks, the water evaporates and the binder remains. The breaking speed is set through the emulsifier and depends on the application: tack coat, surface treatment or cold mix.

Applications: Tack coat · Surface treatment · Cold mix · Maintenance works
Packaging: 208 L drum · IBC 1,000 L · Bulk road tanker
HS code: 2715.00
Supply: On a contract basis

Cutback bitumen

MC / RC / SC

Bitumen cut with solvent for primers and cold processing.

Cutback is made by cutting with a petroleum distillate that evaporates after placement. The designation describes the curing speed: RC rapid with a gasoline fraction, MC medium with kerosene, SC slow with gas oil. It is used mainly as a prime coat on unbound base courses.

Applications: Prime coat · Cold mix construction · Repair
Packaging: 208 L drum · Bulk road tanker
HS code: 2715.00
Supply: On a contract basis
