Elevation control of asphalt paver screeds
Elevation control of the paving screed

Mini-Line® paving control

One factor of building long-lasting asphalt roads that can withstand the strain of traffic year after year is an elevation control system for paver screeds, such as Mini-Line® paving control. It automatically maintains the desired grade when paving, while its ultra-sonic sensors copy the reference with millimetre precision. The paving crew can thoroughly rely on the levelling job of Mini-Line®, and take care for other important tasks of high-quality asphalt laying.

In addition to the mono or multi-sonic sensors G221 and G224, Mini-Line® can operate with our accurate and heavy-duty slope sensor S297, as well as with our linear laser receivers with millimetre resolution. The choice of sensors depends on the paving application. Don't hesitate to contacting us in case you are not sure of the appropriate sensor.

Both ultra-sonic sensors have LEDs indicating the elevation difference to on-grade. A glimpse gives you the peace of mind that the sensors are working and delivering precise signals to the control. When using the G224 Multi-Sonic sensor over a reference stringline it will detect, indicate and send height data, as well as direction (aligning) values, p. e. to control an expendable paving screed.

If the subbase or ground serves as reference for the ultra-sonic height measurement then we recommend using an averaging beam system. It will improve the mat smoothness averaging out irregularities of the ground across the entire span of the beam. There is the Compact Averaging Beam of four sensors available, as well as the Super Averaging Beam of 9 m or 13 m length, for up to 6 ultra-sonic sensors.

The paving control is typically separated in a left and right control loop. At each side there is a HS301 hand-set controller that raises or lowers the left or right tow arm cylinder of the paver. If you'd like to control both tow arms from one central control panel, or if you'd like to have a crossover operation from left to right side (or viceversa), then PL2005 Dual paving control shall be the right choice for you. The panels and all sensors will be connected to the central interface box that controls the valves of the tow arm cylinders.

Paving data monitoring


MatManager is a PC designed for machine use that monitors and saves data of building asphalt roads. Some parameters will be collected automatically by connected sensors, and some parameters will be entered by the operator. This way, material consumption, paving distance and speed, width of screed, machine stops, temperature and other data can be stored, transferred to a server or PC, and reported as proof of your quality job.

AC700 controller and sensor

Another important factor of quality asphalt road building is a continuous material flow and distribution in front of the screed. The AC700 ultra-sonic, non-contact sensor detects the amount of material at the conveyor belt or auger, and signals it to a controller inside the paving machine.

The AC700 controller with keypads and LED-indicator can both detect and regulate the material flow.

Ignition control

Ignition & temperature control

For gas heated paving screeds we supply electronic gas, ignition and flame controllers. The FCE60 is our latest model of ignition boxes. It delivers a 100% compliance with actual EU gas safety and road machinery directives - the best safety for your operating paving crew. Ignition boxes are often built in a loop with temperature sensors and controls. The temperature controls will automatically maintain the optimum operating temperature of the screed without overheating the screed plates while paving.

Joint heater

Joint heater

The Joint heater is an infrared butane gas burner for asphalt pavers assisting in the construction of longitudinal joints. The Joint heater will preheat the edge of the previously laid cold lane just prior to placing the new hot mix lane next to it. The result is a consistent perfect weld of the fresh and the previously laid mats, preventing premature cracking of the joint. We supply you Joint heaters with 4, 6 or 10 burners in a row.
