Asphalt Synchronous Chip Sealer Truck

Sinotruk Howo 24m3 Asphalt Spreader and Distributor Truck Tanzania

Name: Sinotruk Howo 24m3 Asphalt Spreader and Distributor Truck Tanzania
Brand: Sinotruk HOWO

The Sinotruk HOWO 24m3 Asphalt Spreader and Distributor Truck is a dual-tank vehicle built on an 8x4 HOWO chassis for simultaneous asphalt binder spraying and aggregate spreading. It is designed for road maintenance and chip sealing operations in regions with limited access to centralized paving plants, such as rural highways, feeder roads, and urban repair zones in developing markets. The truck delivers consistent, high-coverage application with adjustable spray width and real-time control of bitumen flow based on vehicle speed. It operates in environments where road surfaces are exposed to heavy traffic, extreme heat, and frequent maintenance cycles.

Buyer Profile

Who It Is for

Municipal and regional road authorities in East Africa and Sub-Saharan Africa
Contractors bidding on road maintenance and chip sealing tenders in developing countries
National transport departments managing rural and feeder road networks
Private road maintenance firms operating in low infrastructure regions
Government agencies equipping local road units with durable, low-maintenance vehicles
Infrastructure development contractors working on road upgrades in remote areas

Operating Problems

Problems It Solves

Lack of access to centralized asphalt plants forces long transport times and material cooling
Inconsistent spray patterns from manual or single-point distributors lead to poor bonding
High maintenance costs from poorly insulated tanks and mechanical failures in hot climates
Limited control over aggregate spread rate causes uneven surface texture and premature wear
Single control point leads to operator error and inconsistent application quality
High downtime due to clogged lines or uncontrolled temperature drop in the asphalt tank

Where It Works

Application Scenarios

Rural road maintenance teams in Tanzania and East Africa with no access to fixed paving plants
Municipal road repair crews working on feeder roads and secondary highways with high traffic wear
Contractors performing chip sealing on newly laid asphalt surfaces to improve skid resistance
Emergency resurfacing after heavy rains or flood damage on unpaved or partially paved roads
Road rehabilitation projects in remote mining or agricultural zones where transport is limited
Public works departments managing seasonal road maintenance with tight budgets and limited equipment

Build Materials

Materials

1 mm stainless steel outer shell for asphalt tank with 50 mm insulation layer
Carbon steel frame and substructure for chassis and body support
Stainless steel piping and valves for asphalt delivery system
Aluminium alloy components on the rear working platform and control housing
High-temperature resistant rubber seals on all tank access points
Fire-resistant insulation material in the tank wall and around the burner

How It Is Built

Manufacturing Process

Chassis is received from Sinotruk and wheelbase is verified against the tank layout drawing
Asphalt tank is fabricated from 1 mm stainless steel with 50 mm insulation and welded in place
Gravel silo is assembled from carbon steel with internal baffles to prevent bridging
All piping, pumps, and valves are installed and pressure tested before integration
Control system is programmed with speed-based flow logic and dual interface calibration
Burner and heat transfer system are tested for consistent temperature maintenance
Tank and silo are insulated and sealed, then coated with protective finish
Final assembly includes cab mounting, PTO connection, and control panel installation
Full system test is run on the factory apron with simulated spray and stone spread

Testing

Quality Control

All tanks and pressure components are tested for leaks and structural integrity
Control system is tested under simulated field conditions with speed and flow variation
Temperature control system verified to maintain asphalt within two degrees per hour
100 percent test before delivery with photos and videos sent to buyer before balance payment
Burner and heat transfer system tested for stable operation at full load
Insulation layer thickness measured and confirmed at multiple points on the tank

Comparison

How It Compares With the Alternatives

6x4 asphalt spreader with 8m3 tank	Lower capacity and less stability on rough terrain but easier to maneuver in urban areas
Manual chip sealer with hand-held sprayer	Slower and less consistent application but lower initial cost and simpler maintenance
Single tank asphalt distributor with separate stone spreader	Higher operational complexity and longer setup time but lower cost per unit

Operating Notes

Use Guide

Confirm chassis drive configuration and hand of drive before order to match local road rules
Fill asphalt tank only through the designated inlet and keep the air vent clear
Preheat the asphalt to 140–160°C before application and maintain temperature during transport
Use the cab touch screen to set spray width and flow rate based on vehicle speed
Engage the full power PTO before starting the asphalt pump and burner
After use, activate the automatic blowing device to clear lines and tank residue

Buyer Questions About This Truck

What is the lead time for this asphalt spreader?

Generally 20 days after the advance payment is received. The exact date depends on chassis availability and equipment configuration.
