FAE’s multi-tasking MTH 225 provides flexibility for smaller-scale jobs

FAE has updated its heavy-weight, multi-task attachment with improvements to its mechanism for controlling drilling depth and its water injection system.

The MTH 225 can be used in highway applications such as soil stabilisation, milling thin top layers of road surface or crushing an entire depth of asphalt to turn it into road base. “It can do stones, rocks, asphalt, it can mix. It can do a little bit of everything,” said FAE product manager Lee Smith.

It’s a useful tool for treating materials in situ, says contractor John DeLuca of A. DeLuca Paving, who has trialled the machine. “In New Jersey, we have problems getting rid of old asphalt, it’s expensive to do, so we want to take materials that are already in situ and improve them, using cement as binders.”

With a drilling depth that ranges between 340mm and 500mm, the MTH 225 has counter blades which the operator can adjust in order to control the size of the material being crushed. “With this machine we can shred the asphalt and improve the gradation,” says Deluca.

The improved automatic water system is important for applications such as soil stabilisation where lime cement and water are mixed with the ground to improve its strength. “When you are doing soil cement, you need to be precise with the dosage of water in order to meet the specification,” says DeLuca.

At 2.84m wide, with a working width of 2.32m, the 7,200kg MTH 225 can be used for small and medium jobs, where a standard machine would not fit, or would be expensive to have on hand all the time. One tractor can be used to tow this and other attachments, reducing the machine resource required, says DeLuca.

Apart from its size, the machine has other benefits over a standard Reclaimer, says DeLuca: it can cope with obstacles such as boulders or even lumps of steel, which would damage other machines and put them out of operation. DeLuca has been using MTH attachments on car park paving for warehouse developments, where the ability to cope with unknowns in the ground helps limit downtime.
