Roller Sector Compactor from Infratest
EN 12697/33


For the preparation of hot rolled asphalt samples. The preheated asphalt mix is compacted by a roller segment. Compaction load is applied horizontally using a computer controlled servomotor. A frequency controlled motor moves the mould right/left during the compaction process. The roller segment as well as
the mould is equipped with an electric heating attachment. To remove the sample, the base plate of the mould can be moved in an upward position.

The whole process is controlled by selectable compaction programs via Windows software. The user himself can create and memorize own test sequences. The machine and process control is effected by an integrated input/output unit with touch screen panel.


For taking drilling cores out of asphalt and concrete pavements using a diamond drill bit.

The right hand site operated drilling unit with solid guide pillar is fixed on a single axle trailer with spherical coupler, where the base plate can be lowered.

The solid configuration in addition to the advanced hydraulic drive design ensures a high drilling performance as well as a high durability of the diamond drill bit.

The stainless steel water tank for cooling water is fitted in front of the drilling unit above the axle. Located near the front section are the toolbox, the hydraulic pump and the 4-stroke petrol driven engine with cover hood.

The cooling water supply is carried out by an electrical circulation pump with swivel shaft. Available with manual feed by hand wheel or variable hydraulic feed.
