Description/ Specification of Bitumen Pressure Distributor
A Bitumen Pressure Distributor (BPD) is a specialised road construction machine designed for the uniform spraying of bitumen, emulsion, or other binding agents over a surface before laying aggregates. It is an essential piece of equipment in the surface dressing, tack coat, prime coat, and road maintenance processes. By ensuring an even, controlled layer of binder, it enhances road strength, longevity, and smoothness.
Properties
Uniform Application: The machine ensures consistent binder thickness across the treated surface, reducing wastage and improving adhesion.
• Controlled Spray Rate: Equipped with calibrated valves and nozzles, it can control the application rate (usually measured in liters/m²).
• Heat Retention: Provides insulated tanks to keep the bitumen temperature down, thus reducing re-heating needs.
• Corrosion & Heat Resistance: The components are made of heat-resistant steel with anti-corrosive coatings for exposure to hot binders.
Mobility: It is truck-mounted or towed, so convenient for different road projects.
Working Principle
The fundamental principle of a bitumen pressure distributor involves the pressurisedisedisedised spraying of hot bitumen.
heaters : Bitumen is normally kept in an insulated tank and heated using a diesel-fired burner system for maintaining the spraying temperature to about 150–165°C for paving-grade bitumen.
Pressurization:::: A positive displacement pump or air pressure system pressurizes the binder within the tank.
Spraying: The pressurised bitumen passes through spray bars equipped with multiple nozzles.
The spray bar width can be adjusted to match road width.
Nozzle angles and spacing ensure uniform coverage.
Flow Control: A control system adjusts spray rate depending on vehicle speed, binder viscosity, and application type.
Recirculation: Bitumen is circulated back into the tank when spraying is paused, preventing cooling and clogging.
Features
Insulated storage tank with heating system.
Variable Spray Width (manual or hydraulically adjustable).
Bitumen pump for circulation and spraying.
Calibrated nozzles for precise application.
Speed-linked control system for constant spray rate.
Hand spray lance for patchwork and edges.
Temperature gauge and pressure gauge for monitoring.
Diesel burner with auto-ignition for heating efficiency.
Purpose
The main purpose of a bitumen pressure distributor is to:
Create a uniform tack or prime coat before laying asphalt.
Improve bonding between existing road surfaces and new layers.
Reduce material wastage by perfect binder control.
Improve the road's durability and resistance to weather conditions.

Tack Coat Application: Thin-in layer of bitumen sprayed before overlaying asphalt.
Prime Coat Application: Binder applied over granular base before asphalt surfacing.
Surface Dressing: Bitumen sprayed before spreading aggregates for chip sealing.
Fog Seal: Light spray of diluted bitumen in rejuvenating the aging pavement.
Road Repair & Maintenance: Localized binder application for patchwork.
A bitumen pressure distributor is an indispensable tool in road construction and maintenance. By combining heating, pressurisation, and precise spraying, it ensures optimal binder distribution, leading to stronger, smoother, and longer-lasting roads. With features like adjustable spray widths, calibrated flow control, and efficient heating systems, it significantly improves work efficiency, reduces costs, and ensures high-quality road surfaces.
