摘要: To study the dynamic modulus characteristic of LSPM mixes, test was conducted for Large Stone Permeable Asphalt Mixtures (LSPM ) with neat asphalt and modified range values determined master curves were developed. The magnitude decreased an increase in temperature increased frequency. phase angle as frequency at low temperature. With increase, there a transition interval, where up to frequencies 0.5 Hz, then it started decrease increased. After Master developed by sigmoidal function showed that exhibited higher middle high lower frequencies.
