What is COST ?What is COST ?

~ COST stands for Co-Operation in thefield of Science and Technology

~ Virtually all European Countries (notonly EU) are members

~ Projects are proposed by membercountries (bottom-up)

~ Interested countries join specificprojects

~ Participants represent their countries

How does it work ?How does it work ?

~ By love!

~ COST pays travel & subsistence to meet,employer organisations effectively fund staff

~ Some get state support to participate

~ Level of support doesnt meet need~ So, effectively done by enthusiasts

~ Final output tends to be a statement ofbest practice

~ Performed by steering panel of experts,

~ Not by a contractor!

What is COST 351 ?What is COST 351 ?

~ COST 351 is on Water Movements inRoad Pavements and Embankments

~ Initial proposal by Kent Gustafson (VTI)

~ Coverage:

~ Moisture content in base / sub-base / near-pavement subgrade

~ Water flows in these areas and inpavement drainage systems

~ Water quality

Some Features .Some Features .

~ Zone of interest:

~ where influenced by traffic,

~ To the water table for contaminant seepage,

~ Will draw on in-situ performance datawhenever possible,

~ Include run-off water only as an input forcontaminant movement,

~ Heat-flow studied to understand water flow

driven by freezing or thawing.~ Will produce a textbook, suitable for

practising engineers,
