# Industrial Specification: Compaction System

## 1. Technical Definition
A mechanical subsystem within a road recycling machine responsible for compressing and densifying the recycled asphalt material to form a stable road surface.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 MPa hydraulic pressure, 0.5-2.0 m/s compaction speed, 80-120°C material temperature**. Failure boundary: **Hydraulic pressure exceeding 40 MPa causes seal extrusion, material temperature below 70°C creates insufficient bonding, compaction speed above 2.5 m/s induces material shear failure**, Mechanism: **Seal failure occurs via extrusion when hydraulic pressure exceeds the yield strength of HNBR elastomer (35 MPa). Material bonding failure follows Arrhenius kinetics where temperature below 70°C reduces asphalt binder viscosity above 1000 Pa·s, preventing proper inter-particle adhesion. Shear failure occurs when compaction speed generates shear rates exceeding 10 s⁻¹, surpassing the complex modulus (G*) of recycled asphalt at operating temperature.**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
