The section size of the floating slab will be sirectly related to issues such as vibration and noice control. Bigger concrete section sizes are generally associated with better sound and vibration absorption characteristics

see explanation please
Explanation: It either has to do with thickness or with density. Without more context, it's not possible to decide.
I should then say : "reduced floating slab" OR "thiner..." OR "lighter....." IMHO

Asker: I used "reduced section floating slab", and so will award the points to Mr. Hedger. All the answers and explanations were very helpful, though, in combination. So thanks to all three of you.

Explanation: Hi Jeremy, tricky one this as there are no googles for the term in French, must be new, see extract below for explanation of my choice of translation, good luck!

In all areas special forms of concrete slab track will be used. The slab track form consists of two types:
Precast Concrete Block Trackform (PCBT) and
Isolated Slab Track (IST)
both of which have vibration attenuation capabilities.
PCBT (previously known as LVT or low vibration track) consists of individual pre-cast concrete blocks sitting on top of a rubber microcellular pad. The pad and block are contained within a rubber boot. The PCBT is used in tunnels and at junctions where noise and vibration is not such a sensitive issue.
IST is a new trackform being used for the first time in Hong Kong. It consists of a concrete trough lined with natural rubber ballast mat. The ballast mat was selected after a rigorous testing exercise to check its ability to withstand the intended design life of 50 years.
Within the trough is another concrete block, which is effectively floating, and on tope of this are special low stiffness baseplate fastenings.
IST is used in areas of future residential and commercial development adjacent to the railway which require extensive noise and vibration control.
An alternative trackform to the IST that was considered in the pre-tender evaluations was floating slab track (FST), but this was eliminated due to additional construction cost, extra construction time required, and the fact that the IST trackform could attain the desired level of noise and vibration attenuation.
