By modifying asphalt with high-performance polymers (styrene-butadiene-styrene, SBS, and ethylene-vinyl acetate, EVA), it addresses issues like rutting, cracking, and moisture damage, ensuring long-lasting infrastructure with a service life up to 20 years. The cosolvent system improves polymer dispersion, creating a homogeneous blend with superior mechanical properties.
Extreme Climate Resistance
Maintains flexibility at -30°C (PG 70-22, meeting ASTM D6934) and thermal stability at 82°C (PG 82-22), making it suitable for arctic regions (e.g., Alaska, Siberia) and desert environments (e.g., UAE, Saudi Arabia). The polymer network reduces thermal expansion coefficient by 30%, minimizing thermal cracking.
UV-resistant polymers with carbon black loading of 2–3% prevent oxidation and aging, extending service life by 30% compared to unmodified asphalt. Laboratory tests show <5% mass loss after 1,000 hours of UV exposure (ASTM G154).
High Traffic Load Capacity
Withstands heavy loads up to 20,000 ESALs (Equivalent Single Axle Loads) per day, ideal for highways, airport runways (e.g., Boeing 747 operations), and industrial zones with heavy machinery. The modulus of elasticity at 20°C is 1,500–2,000 MPa, reducing rutting depth by 50% compared to conventional asphalt (rut depth <5 mm after 1 million load cycles).
Ease of Application
Low viscosity at 160–180°C (Brookfield viscosity ≤3,000 mPa·s) allows for smooth mixing with aggregate (140–160°C), reducing energy consumption by 15%. Cold-lay formulations (curing at -10°C) use emulsified polymers, enabling emergency repairs in sub-zero temperatures with full strength development within 48 hours.
Sustainable Design
Incorporates 10–15% recycled polymers (post-consumer plastic waste, tire crumb rubber), aligning with circular economy principles and LEED credits for sustainable infrastructure. Low VOC emissions (<5 g/L) meet EPA Method 24 and EU ECOLOGO standards, reducing construction-site air pollution.
Road Types: Highways (Class I, II), airport runways (PCN ≥50), and heavy-duty industrial roads (e.g., mining haul roads, port access roads).
Climate Zones:
PG 70-22: Cold regions with minimum temperatures -30°C (e.g., Canada, Scandinavia), requiring 5–8 cm thickness for primary roads.
PG 82-22: Hot regions with maximum temperatures 50°C (e.g., Middle East, Australia), suitable for 4–6 cm thickness in urban arterials.
Construction Methods:
Hot mix asphalt (HMA) for primary roads, mixed at 170–180°C with a compaction temperature ≥150°C.
Cold mix for pothole repairs, using 30–40% emulsified polymer content for rapid strength gain in winter conditions.
Q: How does it compare to traditional asphalt?
A: Offers 3x higher fatigue life (≥1 million cycles vs. 300,000 cycles), 50% better moisture resistance (stripping value <5% per AASHTO T283), and 20% lower life-cycle costs due to reduced maintenance.
Q: What is the recommended thickness for pavement?
A: 3–5 cm for light traffic (≤1,000 ESALs/day), 5–8 cm for heavy-duty applications (≥10,000 ESALs/day). Thickness calculations follow AASHTO MEPDG design guidelines.
Q: Can it be used in rainy conditions?
A: Yes, hydrophobic polymers allow installation in light rain (rainfall <2 mm/h), as the cosolvent system prevents moisture-induced stripping. Avoid application during heavy downpours or when the base is wet.
Q: What is the expected service life?
A: 15–20 years under normal traffic (5,000 ESALs/day), with minimal maintenance (e.g., periodic sealcoating every 5 years). In low-traffic areas, service life can extend to 25 years.
Q: How to recycle old pavement containing this material?
A: Recycled asphalt pavement (RAP) can be reused up to 30% in new mixes without compromising performance, following AASHTO R35 guidelines.
