Product Specifications

Technical details and manufacturing context for Asphalt Tank

Definition
The asphalt tank is a critical component of asphalt distributor vehicles that stores, maintains temperature, and dispenses liquid asphalt for road construction and maintenance applications. It features insulation, heating systems, and discharge mechanisms to ensure asphalt remains at optimal viscosity for spraying operations. The tank is typically constructed from carbon steel (e.g., Q235B per GB/T 700) or stainless steel, with insulation materials such as rock wool or polyurethane foam. Capacities for distributor trucks typically range from 3000 to 15000 liters, with heating power between 30 and 120 kW to maintain operating temperatures of 160–200°C. Temperature control accuracy is ±5°C to preserve viscosity, and heat loss rate is ≤2.5°C/h with 80mm insulation at 150°C. Working pressure for the discharge pump inlet is 0.2–0.6 MPa. Insulation thickness varies from 50 to 100 mm. Overall dimensions depend on capacity, ranging from 4000×1800×1800 mm to 7000×2500×2500 mm, and empty weight (excluding trailer frame) is 1500–5000 kg. Electrical supply is three-phase, 380V AC ±10% at 50Hz, with ingress protection ratings of IP54–IP65 for electrical enclosures. These values are typical reference ranges; actual specifications must be confirmed with the manufacturer for specific models and applications. The tank operates by storing liquid asphalt at controlled temperatures using internal heating coils or external heating systems. Insulation minimizes heat loss, while agitation systems prevent asphalt settling. During operation, asphalt is pumped from the tank through spray bars for uniform application on road surfaces. Proper maintenance includes regular inspection of heating elements, insulation integrity, and discharge mechanisms. Failure to maintain temperature can lead to asphalt degradation above 200°C or increased viscosity at lower temperatures, affecting spray quality. Always verify model-specific parameters and compliance with applicable standards with the legal manufacturer or supplier.
Working Principle
The asphalt tank stores liquid asphalt at controlled temperatures using internal heating coils or external heating systems. Insulation minimizes heat loss, while agitation systems prevent asphalt settling. During operation, asphalt is pumped from the tank through spray bars for uniform application on road surfaces. Temperature control maintains the asphalt within 160–200°C to ensure proper viscosity for spraying. The heating system, typically 30–120 kW, is regulated to achieve ±5°C accuracy. The tank's insulation, 50–100 mm thick, reduces heat loss to ≤2.5°C/h under specified conditions. Discharge pressure is maintained at 0.2–0.6 MPa to feed the pump inlet. These parameters ensure consistent performance in road construction and maintenance.

Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric to 0.5 bar (7.25 psi) max, typically non-pressurized with venting
flow rate: Dependent on pump system: 50-200 L/min (13-53 gal/min) typical for distributor trucks
temperature: 150-200°C (302-392°F) typical operating range, up to 250°C (482°F) max with insulation
slurry concentration: Not applicable - designed for pure liquid asphalt, not slurry mixtures
Media Compatibility
✓ PG 64-22 asphalt binder ✓ Polymer-modified asphalt (PMA) ✓ Cutback asphalt (MC-3000)
Unsuitable: Water-based emulsions or aqueous solutions (risk of phase separation and tank corrosion)
Sizing Data Required
  • Required asphalt volume capacity (liters/gallons)
  • Truck chassis weight and space constraints
  • Required heating rate and temperature maintenance capability

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Thermal stress cracking
Cause: Rapid temperature cycling between hot asphalt storage (150-200°C) and ambient conditions, causing differential expansion/contraction in tank walls and welds
Internal corrosion and material degradation
Cause: Chemical attack from sulfur compounds and organic acids in asphalt, combined with moisture ingress during storage or temperature changes leading to acidic condensation
Maintenance Indicators
  • Visible weeping or asphalt seepage along weld seams or tank shell, indicating material fatigue or corrosion
  • Abnormal temperature readings or hot spots on tank exterior during thermal imaging, suggesting insulation failure or internal heating element problems
Engineering Tips
  • Implement controlled heating/cooling protocols with maximum temperature gradients of 25°C per hour to minimize thermal shock and stress accumulation
  • Install and maintain proper nitrogen blanketing systems to create inert atmosphere above asphalt level, preventing oxidation and moisture condensation
