What water content is ideal for foam asphalt?
For optimal foam quality, water content of 2–3% of bitumen weight is recommended. This achieves expansion ratio >10 and half-life >8s per specification.
RAP content limit for road base?
RAP content up to 100% is achievable with proper mix design. Field data from Henan G327 confirmed full RAP reuse with structural strength exceeding hot-mix.
