摘要

本研究的目的是在开发的弹性模量主曲线的基础上，评估在沥青混合料中使用颗粒状钮扣岩沥青(BRA)改性剂粘结剂的影响。这涉及根据澳大利亚标准AS2891.13.1-1995在UTM25测试设备上进行间接拉伸刚度模量(ITSM)的实验室评估。在5℃、15℃、25℃、40℃和60℃五种不同的试验温度下，以及0.33 Hz、0.50 Hz和1.0 Hz三种不同的加载频率下，对密度级配(10 mm)未改性和bra改性沥青混合料进行了试验。结果表明:在高-中温范围和低频范围内，bra改性沥青混合料的弹性模量高于未改性沥青混合料的弹性模量;研究发现，bra改性沥青混合料的粘弹性行为比未改性沥青混合料的粘弹性行为更为明显。

Resilient modulus master curve for BRA-modified asphalt mixtures

The objective of this research was to evaluate the impact of using granular Buton Rock Asphalt (BRA) modifier binder in asphalt mixtures, based on the developed resilient modulus master curve. This involved laboratory evaluation of indirect tensile stiffness modulus (ITSM) on UTM25 test equipment in accordance with the Australian Standard AS2891.13.1-1995. The test was applied to dense-graded (10 mm) unmodified and BRA-modified asphalt mixtures at five different test temperatures: 5°C, 15°C, 25°C, 40°C and 60°C and three different loading frequencies: 0.33 Hz, 0.50 Hz and 1.0 Hz. The results showed that in the high-intermediate temperature range and at low frequency the resilient modulus of BRA-modified asphalt mixtures was higher than the modulus of unmodified mixtures. It was discovered that the viscoelastic behavior of BRA-modified asphalt mixtures was more pronounced than in the case of unmodified asphalt mixtures.
