Open-Graded Friction Course
Applications: high-speed roads, wet conditions.
Traits: improved drainage and reduced hydroplaning.
Mix specifications
Asphalt mix specifications.
Below are the standard specifications common to Gencor plant production. These are typical mix designs and binder grades produced on Gencor-equipped equipment . Please confirm exact availability and current offerings with EAM before specifying.
Hot Mix Asphalt
Hot Mix Asphalt (HMA)
Applications: roads, parking lots, driveways, and resurfacing. High durability and stable performance under heavy traffic.
| Spec | Type | Typical Use |
|---|---|---|
| BM-1 | Base mix | Base course |
Surface and structural mixes are produced to Superpave (SP) gradations. See Superpave Performance Mixes below.
Superpave
Superpave Performance Mixes
Designed for rut resistance, long life, and high-traffic conditions. Gradations are paired with performance-graded (PG) binders to suit project loading and climate.
Gradations
| Grade | Nominal Max Aggregate |
|---|---|
| SP-9.5 | 9.5 mm - fine surface |
| SP-12.5 | 12.5 mm - surface / structural |
| SP-19 | 19 mm - structural / base |
PG Binder Options
| Binder | Notes |
|---|---|
| PG 64-22 | Standard performance grade |
| PG 67-22 | Standard performance grade |
| PG 76-22 | Polymer-modified |
Polymer-Modified
Polymer-Modified Asphalt
Applications: high-stress intersections, trucking routes, and industrial facilities where pavement endures concentrated loads and heat.
PG 76-22 polymer
High-stress duty
Performance Traits
- Improved elasticity
- Flexes under load and recovers, resisting cracking.
- Superior rut resistance
- Holds shape at intersections and under stop-and-go traffic.
- Stronger under Florida heat
- Maintains stability through high pavement temperatures.
Specialty Mixes
Surface & drainage mixes.
Engineered mixes for high-speed roads, wet conditions, and stormwater management.
