Experimental Research on Preparing Conductive SMA Doped Graphite
Conductive stone mastic asphalt (SMA) mixture is a kind of asphalt pavement material with excellent electrical performance, produced through adding conductive paste material to the mixture. It was produced by using graphite as conductive particle, and a kind of resistance test method of embedding showerhead electrode was designed in the present study. It was found that graphite can improve electrical performance of SMA mixture effectively. Fractal theory finds the reason why different graphite have various effect in improving electrical performance of mixture is their model parameters are diverse; electrical performance of conductive SMA mixture containing graphite is steady, and will not change with time; with the increase of graphite content, temperature sensitivity of conductive SMA decreases gradually and its linear V-I characteristic is more obvious; the present research shows: the conductive mechanism of conductive SMA is the result of combined action of conductive pathway, tunneling effect and field emission.
