# Industrial Specification: RAP Storage Bin

## 1. Technical Definition
A storage container designed to hold and discharge Recycled Asphalt Pavement (RAP) material within an asphalt mixing plant system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-2.5 bar internal pressure, -20°C to 80°C ambient temperature**. Failure boundary: **3.0 bar internal pressure causing structural deformation, 100°C material temperature causing asphalt binder degradation**, Mechanism: **Von Mises yield criterion exceeding 250 MPa at 3.0 bar pressure, Arrhenius equation kinetics accelerating binder oxidation at 100°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Material bridging due to RAP moisture content exceeding 3% by mass | 8 | Flow obstruction causing discharge rate reduction to 0 kg/min | Installation of pneumatic vibrators with 0.5-1.0 Hz frequency and 2.0 kN force rating |
| Corrosion from sulfuric acid formation at pH &lt;4.0 due to sulfur compounds in RAP | 8 | Wall thickness reduction exceeding 1.5 mm/year leading to structural failure | Application of 3.0 mm epoxy-polyurethane coating with 95% crosslink density |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

- **Caution**: 
- **Caution**: 

### Q: What materials are used in the construction of this RAP storage bin?
**A**: The RAP storage bin is constructed from structural steel (Q235/Q345) for the main framework, with abrasion-resistant steel plates used for wear liners to withstand the abrasive nature of recycled asphalt pavement material.

### Q: How does the discharge system work in this RAP storage bin?
**A**: The bin features a discharge feeder system with vibrators that ensure consistent, controlled material flow from the bin to the asphalt mixing plant, preventing bridging and maintaining optimal production efficiency.

### Q: What monitoring systems are included with the RAP storage bin?
**A**: The bin includes a level sensor and load cell system that provides real-time monitoring of material levels and weight, allowing for precise inventory management and automated refill alerts.
