Technical Support and Availability
RHEOFALT® HP AM is a pure liquid resin additive which is easy to dose at normal ambient temperatures between 15-30°C without any heating requirement. When the climate is colder (below 15°C), dosing efficiency can be improved by gently warming the product to 15-20 degrees Celsius, which reduces viscosity and enhances flow characteristics while preserving the bio-polymer structure. Never heat above 60°C to prevent degradation.
The product can be added using three proven methods: (1) Direct addition into the pug mill of the hot mix asphalt plant during the mixing cycle, allowing 45-60 seconds of mixing time for uniform distribution; (2) Pre-blending with fresh virgin bitumen at 140-160°C before introducing RAP material, ideal for partial replacement scenarios; (3) Surface application to RAP stockpiles with 24-48 hours penetration time, followed by stockpile turning for distribution. CRITICAL APPLICATION GUIDANCE: When adding RHEOFALT® HP AM directly to RAP material, it MUST be added at the discharge end of the heating drum, NOT before material enters the drum, to prevent premature volatilization of the bio-polymer components at high temperatures.

Frequently Asked Questions
What is RHEOFALT® HP AM and how is it different from conventional rejuvenators?
RHEOFALT® HP AM is a 100% renewable bio-polymeric rejuvenator that works by isolating and stabilizing the polar effect of asphaltenes in aged bitumen, rather than simply diluting them like conventional rejuvenators. This unique mechanism preserves the colloidal balance of the bitumen, enables 100% bitumen reusability without virgin material supplementation, and provides superior long-term performance. The technology has been validated through extensive research by IIT Bombay specifically for Indian RAP materials and road conditions, demonstrating enhanced penetration recovery, improved temperature susceptibility across India's extreme climate range, and significantly better fatigue and rutting resistance compared to conventional approaches.
What percentage of RAP can I use with RHEOFALT® HP AM?
RHEOFALT® HP AM enables up to 100% RAP content in asphalt mixes. The IIT Bombay validation study specifically tested and confirmed optimal performance at 100% RAP with 0.3% RHEOFALT® HP AM dosage, demonstrating that properties comparable to or better than virgin bitumen mixes can be achieved. However, the actual RAP content used in practice should be determined based on project specifications, local regulatory requirements, available RAP quality and characteristics, mix design objectives, and performance requirements. Common applications range from 40% RAP for conservative specifications to 100% RAP for sustainability-focused projects. VUBS Corporation provides comprehensive mix design support to determine the optimal RAP percentage for your specific application.
How much RHEOFALT® HP AM should I add to my asphalt mix?
The recommended dosage range is 0.2% to 0.5% by weight of RAP material. For most applications, 0.3% provides the optimal balance of performance and cost-effectiveness, as validated by IIT Bombay research for 100% RAP mixes. This dosage successfully restores aged bitumen properties to near-virgin levels. Severely aged RAP or RAP from harsh climatic exposure may require dosages up to 0.8% for complete rejuvenation. The optimal dosage for your specific application depends on RAP age and condition, original binder grade, degree of oxidation, target performance specifications, and climatic conditions. Always conduct laboratory trial mixes, perform performance testing (penetration, viscosity, DSR, MSCR), and validate field performance before full-scale implementation. VUBS Corporation provides technical support for dosage optimization based on your RAP characteristics and project requirements.
Can RHEOFALT® HP AM be used in cold weather or cold regions?
Yes, RHEOFALT® HP AM actually improves low-temperature performance of recycled asphalt pavements significantly. The bio-polymeric rejuvenation mechanism restores flexibility and relaxation properties to aged bitumen, enabling pavements to resist thermal cracking at temperatures down to -15°C. This makes it ideal for cold regions and seasonal temperature variations across India. For dosing the product itself in cold weather (ambient temperatures below 15°C), the viscosity can be reduced by gently warming RHEOFALT® HP AM to 15-20°C before dosing, which improves flow characteristics and ensures even distribution. Never heat above 60°C to preserve the bio-polymer structure. The product maintains its rejuvenating effectiveness across all climatic zones from Himalayan cold regions to tropical coastal areas, as validated by IIT Bombay's temperature susceptibility testing.
What are the environmental benefits of using RHEOFALT® HP AM?
RHEOFALT® HP AM delivers exceptional and quantified sustainability benefits. It is manufactured from 100% renewable bio-based natural plant resins, completely eliminating petroleum-derived components. Environmental impact studies demonstrate that using 100% RAP with 0.3% RHEOFALT® HP AM reduces CO₂ emissions from 47.41 kg to 34.06 kg per metric ton of asphalt - a remarkable 28% carbon footprint reduction. The technology enables up to 100% virgin bitumen replacement, conserving finite petroleum resources and reducing dependence on crude oil imports. High RAP utilization diverts millions of tons of waste asphalt from landfills annually, supporting circular economy principles. Reduced aggregate quarrying minimizes environmental impacts including habitat destruction, energy consumption, and dust emissions. The product supports achievement of green building certifications (LEED, IGBC), compliance with sustainable procurement policies, and contributes to India's climate commitments under international agreements. The Environmental Cost Indicator (ECI) for 100% RAP mixes with RHEOFALT® HP AM is significantly lower than conventional asphalt production methods.
Is RHEOFALT® HP AM approved for use in Indian road projects?
Yes, RHEOFALT® HP AM has been extensively validated through a comprehensive research collaboration with the Indian Institute of Technology (IIT) Bombay specifically for Indian RAP materials and road conditions. The study evaluated performance characteristics critical to Indian pavements including temperature susceptibility across India's extreme climate range (+65°C to -5°C), fatigue resistance under heavy traffic loading, rutting performance in hot climates, and aging resistance for long-term durability. The technology meets Indian Roads Congress (IRC) specifications for asphalt rejuvenators and is approved for use in government (NHAI, state PWD, PMGSY) and private road projects. While BIS (Bureau of Indian Standards) certification is currently in application process, the IIT Bombay validation and IRC compliance provide strong technical credibility. VUBS Corporation, as the exclusive all-India distributor, provides comprehensive technical support for specification compliance, mix design approval, quality control protocols, and project implementation guidance to ensure successful adoption in Indian infrastructure projects.
How should RHEOFALT® HP AM be added to the asphalt mix?
There are three proven application methods: (1) Direct Pug Mill Addition - Add RHEOFALT® HP AM directly into the hot mix plant pug mill during the mixing cycle. Heat RAP to standard mixing temperature (150-165°C), dose the rejuvenator, and mix for extended duration (45-60 seconds) to ensure uniform distribution. This is the most common method for production facilities. (2) Blending with Virgin Bitumen - Pre-mix RHEOFALT® HP AM with heated virgin bitumen (140-160°C) before introducing RAP material. This method is ideal for partial RAP replacement scenarios and ensures thorough distribution. (3) RAP Stockpile Treatment - Spray RHEOFALT® HP AM onto RAP stockpiles, allow 24-48 hours penetration time, turn the stockpile for distribution, then process through the hot mix plant. CRITICAL APPLICATION GUIDANCE: When adding directly to RAP, the rejuvenator MUST be applied at the discharge end of the heating drum, NOT before material enters the drum. Adding before the drum causes premature volatilization at high temperatures and reduces effectiveness. For cold weather (below 15°C), warm the product to 15-20°C for better flow. VUBS Corporation provides on-site application training and technical support to ensure optimal implementation.
