VTB Thermobox Asphalt Patching Truck

VTB Thermobox Asphalt Patching Truck

An asphalt patching truck carries hot mix asphalt from the plant to the job and keeps it at working temperature until the last pothole is filled. A crew can repair potholes, trench reinstatements and edge breaks without returning to the plant for fresh material.

The Vimpo VTB Thermobox mounts on the customer's own truck. Its insulated V-shaped hopper holds 5 – 8 m³ of material, depending on the chassis. Thermal oil or electric heating keeps the mix hot, and a hydraulic auger discharges it straight into the hole. The emulsion tank, the hydraulics, the tool cabinets and the compactor storage are on the same truck.

How Does an Asphalt Patching Truck Work?

Material Flow

Hot mix is loaded into the hopper at the asphalt plant. The 100 mm rock wool insulation and the heating system keep the material at an even temperature during transport and work. At the repair, the operator opens the hydraulic auger at the hopper base and the material flows through the chute into the pothole.

Heating

With thermal oil heating, a diesel burner heats oil that circulates through a jacket around the hopper. The digital thermostat controls the oil temperature up to 280 °C and the system has over-temperature and low oil level protection. An electrically heated version is also available.

VTB Thermobox Features

Insulated V-Shaped Hopper

The hopper is made of 4 mm steel plate with a reinforced welded structure. Its V shape guides the material to the auger. It is insulated with 100 mm rock wool, cladded outside, and closed with a hydraulic top cover.

Thermal Oil or Electric Heating

The thermal oil system has a diesel burner with automatic ignition, flame control and safety shutdown, an expansion tank with level indicator and its own diesel tank. The electric version heats the hopper walls electrically.

Hydraulic Auger and Chute

A hydraulically driven screw conveyor at the bottom of the hopper discharges the material through the chute. The operator controls the flow at the repair point.

Extended Reach Discharge Arm (Option)

The hydraulic discharge arm turns through 180° and reaches 1.5 m from the truck. The operator places the hot mix directly into the hole on the left, at the rear or on the right of the truck.

Emulsion Tank and Hand Spray Bar

The emulsion tank holds at least 150 L and has a thermometer, a ¾" drain valve and a manual shut-off valve. The hand spray bar applies the tack coat before filling.

PTO Hydraulics and Control Panel

A PTO-driven hydraulic pump delivers at least 35 L/min at 140 bar to the auger, the top cover and the optional breaker. Temperature, emulsion pump and hydraulic functions are controlled from the rear control panel.

Everything on Board

Water tank (min. 30 L),diesel tank (min. 50 L),hydraulic oil tank (min. 50 L) with level indicator and filter, tool cabinets, compactor storage cabinet, lighting and beacons, a diesel cleaning spray bar and a fire extinguisher.

Fits Your Truck

The equipment is built for the customer's truck chassis. It sits on a 6 mm auxiliary subframe with bolted connections, and the hopper volume is matched to the chassis.

VTB Thermobox Technical Specifications

Optional Equipment

The VTB Thermobox can be supplied with:

• Plate compactor: max. 100 kg, plate min. 40 × 50 cm, petrol engine min. 4 HP, water spray
• Hydraulic jack hammer: max. 29 kg, min. 110 bar, 20 – 30 L/min, 1,200 – 2,000 blows/min, 10 m hose
• Compactor lift: for loading the compactor onto the truck
• Roller carrying system: for a small roller on the truck
• Extended reach discharge arm: hydraulic, turns 180°, reach 1.5 m

Pothole Repair with the VTB Thermobox

A typical repair takes four steps: cut and clean the damaged area, spray the tack coat, fill with hot mix from the auger and compact. The breaker and the compactor work from the same truck, so one crew completes the repair at one stop. The VTB Thermobox is used by municipalities and road maintenance teams for potholes, trench reinstatements, utility cuts and edge repairs.

Asphalt Patching Truck Frequently Asked Questions

What does an asphalt patching truck do?

It carries hot mix asphalt to the job, keeps it at working temperature and discharges it into potholes and trenches. Emulsion, tools and the compactor travel on the same truck.

How much material does the VTB Thermobox carry?

The hopper holds 5 – 8 m³ gross, depending on the truck chassis.

Thermal oil or electric heating?

Thermal oil heating uses a diesel burner and works independently of an external power supply. The electric version heats the hopper walls electrically. We recommend the system after reviewing your work pattern.

Is the truck included?

No. The equipment is designed for the customer's truck and mounted on a bolted auxiliary subframe.

Which options are available?

A plate compactor, a hydraulic jack hammer, a compactor lift and a roller carrying system.
