Tri-Axle Bitumen Tanker Trailer for Asphalt Logistics

Overview

Designed for the safe and efficient transportation of hot bitumen and asphalt, the Tri-Axle Bitumen Tanker Trailer features a thermally insulated 35,000-liter tank and corrosion-resistant interior, ensuring material integrity during long-haul journeys. With a tri-axle air suspension system and precision temperature control, this trailer maintains asphalt workability (160–180°C) for up to 8 hours, critical for large-scale road construction projects.

Features

Thermal Insulation System

Dual-Layer Insulation: 100mm rock wool core (thermal conductivity 0.04 W/m·K) wrapped in a 2mm aluminum outer shell, reducing heat loss to 15°C/hour at -10°C ambient temperature—30% more efficient than standard fiberglass insulation.

Heating Options: Optional 50kW diesel-fired heater (fuel consumption 5L/hour) or steam coil integration (1.5bar pressure), reheating bitumen from 140°C to 170°C in 30 minutes—ideal for delays at toll stations or traffic jams.

Corrosion-Resistant Design

Internal Coating: Food-grade epoxy resin lining resists bitumen adhesion and chemical corrosion, enabling quick cleaning (30-minute turnaround) and reducing maintenance downtime by 40%.

Stainless Steel Fittings: All valves and pipelines constructed from 316L stainless steel (UNS S31603), compliant with EN 10216-5 (high-temperature pipe standard) and resistant to sulfuric acid (30% concentration, 60°C).

Efficient Loading/Unloading

Top Loading Hatch: 600mm diameter hinged hatch with gas spring assist (150N force) and anti-slip grip, paired with a bottom discharge valve (DN150, flow rate 200L/min) for gravity unloading (15° slope) or pump-driven discharge (compatible with 50m suction hoses).

Vortex Mixing System: Three 1.5m stainless steel agitators (30RPM rotation), preventing sedimentation in multi-grade asphalt blends (e.g., PG 64-22, PG 70-28) and ensuring ±5% viscosity uniformity.

Safety-Centric Engineering

Pressure Relief Valve: Automatically activates at 1.5 bar overpressure, compliant with ADR/RID Chapter 7.2 (dangerous goods transport) and capable of discharging 500L/min to prevent tank rupture.

Grounding System: Conductive rubber strips (surface resistance <10Ω) with automatic reel retraction, eliminating static electricity risks during loading—meeting ISO 28318:2011 (electrostatic safety for petroleum products).

Application

Road Construction: Transports hot-mix asphalt (170°C) to paving sites for highway resurfacing (e.g., 50km/hour delivery radius), maintaining temperature within ±5°C of target for immediate use in roller compacting.

Bitumen Distribution: Delivers bulk bitumen (32,000L per trip) to storage terminals, supporting regional asphalt plants with just-in-time inventory—used by major contractors for 20% faster project completion.

Industrial Heating: Suitable for transporting molten sulfur (130–160°C) and other high-temperature fluids (up to 200°C), with optional thermal jacket reinforcement for arctic climates (-40°C ambient).
