Polymer Modified Bitumen (PMB) Plant
PMB Plant is designed to produce polymer modified bitumen by blending polymers like SBS or EVA with bitumen, enhancing strength, elasticity, and resistance to temperature variations for premium road construction.
Description
Aimax PMB Plant is used to produce polymer modified bitumen by blending thermoplastic polymers such as SBS or EVA into hot bitumen. This process enhances elasticity, adhesion, and resistance to deformation under heavy loads and temperature changes.
The plant uses a high shear mixing system to ensure uniform dispersion of polymer into bitumen. Controlled processing ensures consistent quality and stability of the final product.
PMB is ideal for expressways, flyovers, bridges, and urban roads where high performance and durability are required. It significantly reduces road maintenance frequency and improves overall lifecycle performance.
CRMB Plant vs PMB Plant – Which One Should You Choose?
Choosing the right modified bitumen plant depends on your project type, budget, and performance requirements. Here’s a clear comparison to help you decide:
Difference Table (CRMB vs PMB)
| Parameter | CRMB Plant | PMB Plant |
| Material Used | Crumb Rubber (Waste Tyres) | Polymer (SBS / EVA) |
| Cost Factor | More economical | Higher initial cost |
| Road Performance | High flexibility (anti-cracking) | High strength (anti-deformation) |
| Ideal Projects | Rural roads, highways, PMGSY | Expressways, city roads, bridges |
| Mixing Process | Rubber digestion required | Polymer blending (precision) |
| Production Time | Longer | Faster |
| Storage Stability | Low (needs immediate use) | High (can be stored longer) |
| Eco-Friendly | Yes (recycled material) | Limited |
| Maintenance | Moderate | Slightly higher |
| Operator Skill | Medium | High (controlled system) |
