Who said that it is at all possible?

Dear Sir

I think in this work " Xiaoming L, Shaopeng W. Research on the conductive asphalt concrete’s piezoresistivity effect and its mechanism. Constr Build Mater 2009; 23: 2752–2756."you can find some answer

Dear Pr Peinado

Thank you for your answer and your help.

I red your paper which entitled "Open-grade wearing course of asphalt mixture containing ferrite for use as ferromagnetic pavement" I found it very important and it adds a lot of things new in the field of energy.

Dear Bachir Glaoui,

I think that the AC technique, in particular, impedance spectroscopy will be one of the best for you needs. I am shure you will be able to find necessary information in Internet.

Dear Pr Brus,

Thank you very much on your answer, which help me to search on internet and get a lot of information

Dear Bachir Glaoui,

Let me to recomend you another work very interesting

"Nickel particle-based self-sensing pavement for vehicle detection". Measurement 44(2011) 1645-1650. Baoguo Han and others.

I think , in this work you can find examples and references for your work.

Best Regards
