(OP)
I am doing an investigation on piled slab that will be used to carry roadway embankment through weak soil.
Can anybody shed some light on this topic?

When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: piled slab
I do not want to sound harsh, it sounds like you are venturing to an area that you do not feel comfortable with. Tell us more about your qualifications and the project.
This type of construction is used in some airport runways and slabs that is supported by poor soil.
Are you about to design such system or are you performing forensic type investigation?

RE: piled slab
Geotextiles may be an option, but I would expect that this would already have been considered before looking at piles.
There are jet grouting column ground improvement methods which probably fall under the category of "piles". These are frequently used on highway projects (in Asia for sure) and can be looked up on the internet.
RE: piled slab
It is common to use either cement (CSM - cement stabilised material) or lime to improve the existing soils either by pre-mixing in a pug mill or mix in-place with a rotovating type equipment, this is generally where it is cost effective to re-use the original soil rather than haul new material. It appears that your situation requires deeper treatment and cement columns may be suitable.
