I am looking for information on concrete RH in bridges / viaducts and in concrete road pavements. The data would be perfect as in the article:
http://www.sciencedirect.com/science/article/pii/S0950061800000593
Long term measurements + external conditions.
Humidity measurement by electrical humidity probes is a standard
method. The electrical conductivity is measured between two “steel needles, which are pressed into the wood. The electrical conductivity that is recorded on the apparatus (e.g. Protiometer Timber Master) correlates well with the water content in the wood (water
percent). The temperature has only minor influence on the electrical conductivity in wood, which is not the case in concrete. This method has been used in few concrete structures in the UK and Denmark.
Dear Sir,
pl check it.

Dear Sirs,
Thank You for the answears. I am rather looking not method of measurement (I use Vaisala equipment and it works OK) but long term data with RH in structure or pavement.
Something like this (pages 41-42)
