Research on the Electrical Energy of Piezoelectric-embedded Asphalt Mixture

摘要

There is an important effect on road safety with no lighting facilities near the wild road. With the piezoelectric materials embedded in the asphalt concrete as the smart aggregates, the piezoelectric asphalt concrete transforms the vibrational energy of road surface into electrical energy, to supply the road lighting facilities or be stored up. In this study, the electrical energy of piezoelectric-embedded asphalt mixture by using UTM and wheel tester. The results show that PMnS-PZN-PZT ceramic doped with 0.45 wt% Fe_2O_3 (4 mm×8 pieces) be embedded in the AC-10 asphalt concrete which can obtain well road performance and micropower electrical energy.
