WorldPaveAI is a free AI-powered platform for asphalt binder selection, pavement design, and road infrastructure intelligence. It provides location-aware bitumen grade recommendations following IRC, MoRTH, AASHTO, Superpave, EN 12591, Austroads and 50+ country standards.

How does AI asphalt binder selection work?

WorldPaveAI uses the location's GPS coordinates to fetch real pavement temperatures (7-day max and design winter low), then applies the relevant national standard (IRC, AASHTO Superpave PG, EN 12591, etc.) to recommend the correct VG grade, PG grade, or EN grade bitumen, plus PMB or CRMB options for heavy traffic conditions.

Which pavement design standards does WorldPaveAI support?

WorldPaveAI supports IRC 37:2018, IRC:SP-20, MoRTH specifications (India), AASHTO 93 and Superpave (USA/Canada), EN 12591 and EN 14023 (Europe), Austroads (Australia/NZ), SATCC (Southern Africa), MOMRA (Saudi Arabia), Ashghal (Qatar), MOT UAE, and standards from 50+ countries.

Is WorldPaveAI free to use?

Yes. WorldPaveAI is completely free to use for asphalt binder selection, pavement design, bitumen grade recommendations, and road infrastructure intelligence. No registration is required to get results.

Does WorldPaveAI support airport pavement design?

Yes. WorldPaveAI supports airport and airfield pavement design including runway, taxiway, and apron pavements, with reference to FAA AC 150/5370-10, ICAO guidelines, and national airport pavement standards.

What is VG-30 bitumen?

VG-30 (Viscosity Grade 30) is an Indian road bitumen per IS 73:2013. Absolute viscosity 2400-3600 Poise at 60°C, softening point ≥47°C, penetration 45-59 dmm. Standard grade for national and state highways in India (IRC Cat 3-6). For expressways and hot zones (T₂₀ₘₘ >55°C), VG-40 or PMB required per MoRTH Apr-2024 circular.

What is the difference between PMB and CRMB bitumen?

PMB (Polymer Modified Bitumen) uses SBS/SBR polymers — grades: Type I PMB 70 (SP ≥50°C), Type II PMB 40 (≥55°C), Type III PMB 45 (≥60°C) per IS 15462:2019. CRMB (Crumb Rubber Modified Bitumen) uses recycled tyre rubber — grades CRMB 55/60/65 by softening point. PMB for new expressways; CRMB for sustainable NH wearing courses. Both improve rutting resistance over standard VG grades.

How to calculate T20mm pavement design temperature?

AASHTO PP 66 formula: T₂₀ₘₘ = 0.9645 × [Tair,max − 0.00618×Lat² + 0.2289×Lat + 42.2] − 17.78. Tair,max = 7-day maximum air temperature; Lat = absolute latitude in degrees. WorldPaveAI fetches live weather data and calculates automatically for any GPS location.

Which PG grade for Gulf desert expressways?

Gulf GCC expressways: PG 76-10 PMB mandatory (Qatar MMUP-2022, Abu Dhabi DoT, Saudi SASO 5005). PG 82-10 for extreme desert (Riyadh, Rub al Khali). Hamburg HWT ≤9mm at 60°C. MSCR H-grade Jnr ≤2.0 for expressways; E-grade Jnr ≤0.5 for airport aprons.

What Superpave Ndes gyrations are required?

Per AASHTO R35-23: 30M = 125-150. Ninitial ≤89% Gmm to prevent early compaction. WorldPaveAI displays Ndes recommendation with the binder grade.

Which bitumen grade for hot desert climate?

Hot desert (T₂₀ₘₘ >65°C): PMB SP ≥70°C — India PMB 45, Gulf PG 76-10, Australia A35E, Europe PMB 10/40-65, China SBS-I-C. Extreme desert (T₂₀ₘₘ >75°C): PG 82-10 or PG 88-10, MSCR H/E-grade, Hamburg HWT ≤9mm, SMA wearing course mandatory.

What is MSCR test for modified bitumen?

MSCR (Multiple Stress Creep Recovery) per AASHTO T350/M332-23 measures Jnr (non-recoverable creep compliance). Grades: S (Jnr ≤4.0), H-Heavy (≤2.0), V-Very Heavy (≤1.0), E-Extreme (≤0.5 kPa⁻¹). H-grade required for highway expressways >10M ESALs in USA and Gulf. Recovery %R also specified for polymer quality.

How does climate change affect pavement design?

IPCC AR6 projects +1.2-2.7°C by 2050 (SSP1-2.6 to SSP5-8.5), potentially upgrading PG high-temp grade and requiring higher SP bitumen. Increased rainfall raises stripping risk. WorldPaveAI shows all scenarios in its Climate Intelligence Layer with binder grade shift projections and design reliability recommendations.

What road standards are used in Southeast Asia?

Malaysia: JKR ATJ 2022 (PMB mandatory highway WC ≥10M ESALs, TSR ≥80%). Indonesia: Bina Marga SNI 6753:2022. Philippines: DPWH DO 88-2022 (AASHTO T283 adopted). Thailand: TIS 999 + DOH expressway PMB. Vietnam: MOT Superpave PG (2022). Singapore: LTA road specification. All based on ASTM D3381 pen grades nationally.

Which pavement standards are used in Australia?

Austroads AGPT04B and AS 2008:2013 viscosity grading (Class 170 to 600) with PMB A-grades per AGPT/T190-22. SGC Locking Point preferred. State agencies: VicRoads (VIC), TMR (QLD), MRWA (WA), DPTI (SA), RMS NSW. Wheel track WTT ≤4-5mm at 60°C.

What is SMA Stone Matrix Asphalt?

SMA is a high-performance gap-graded wearing course: stone skeleton (VMA ≥17%), PMB binder 6-7%, cellulose fibre ≥0.3%, drain-down ≤0.2-0.3%. Standards: IS 17127:2019 India, EN 13108-5 Europe, JTG F40 China (DS ≥3000), NEXCO Japan. WorldPaveAI recommends SMA for expressways, urban arterials, airport taxiways.

What are EN 12591 bitumen grades for European roads?

EN 12591:2009 pen grades: 160/220 (cold regions), 100/150 (cold alpine), 70/100 (standard roads), 50/70 (motorway standard), 35/50 (motorway heavy), 20/30 (Autobahn/alpine). PMB per EN 14023: 45/80-55, 25/55-55, 10/40-65, 10/40-70. WTSair limits per EN 12697-22 national annex: ≤0.06 (strictest), ≤0.10, ≤0.20 mm/1000 cycles.

What is CBR and how is it used in pavement design?

CBR (California Bearing Ratio) measures subgrade soil strength as % of standard crushed stone. IRC:37-2018 uses CBR 2-30% for pavement thickness. AASHTO 93 converts: MR = 17.6 × CBR^0.64 MPa. CBR <3% needs capping or stabilisation. WorldPaveAI uses CBR for structural failure risk score and pavement layer thickness calculation.

What is Hamburg HWT test for asphalt?

Hamburg Wheel Track Test (AASHTO T324): 20,000 steel wheel passes on submerged asphalt specimens at 50-60°C. Measures rutting depth and stripping. Limits: USA ≤12.5mm at 50°C; Gulf ≤9mm at 60°C (Qatar MMUP); India DS equivalent ≥1000-3000 cycles/mm IS 9382. Predicts field rutting performance.

Can WorldPaveAI be used for airport pavement design?

Yes. WorldPaveAI covers airport aprons and runways with FAA P-401 (PG 76-16/82-16), ICAO Annex 14, EASA CS-ADR, AAI/MoCA India airport spec, JCAB Japan.
