Abstract:
Cured epoxy resin asphalt specimens with four kinds of crossing density were analyzed by DMA(dynastic mechanics analyzer)with 10 Hz frequency in temperature range from -30 ℃ to 70 ℃. The results show that high crossing density specimens present glass state, transition state and rubbery state in temperature range from -30 ℃ to 70 ℃, while glass state, transition state for low crossing density material. The curves of loss modulus and loss tangent show single peak for either high or low crossing density material. The glass transition temperatures deduce from curves of storage modulus and loss modulus are consistent, the range from 14 ℃ to 17 ℃ lower than that from curves of loss tangent, the SEM(scanning electron microscope)observation shows that the section appeares irregular with broken crossing thread for low crossing density specimens, while smooth for those with high crossing density. 5 tabs, 4 figs, 10 refs.
