乳化沥青冷再生在甬台温高速宁波试验段的应用

摘要

The early strength of strengthening layer is required high in cold recycling constructions.Cold recycling mixture with high early strength and road performance was produced in this study by gradation,emulsified asphalt and inorganic binding material optimization.The effect of construction in the field was good enough for structural strength.It proved that cold recycling mixture could be used in structural reinforcement.%该文针对实体工程中对冷再生补强层早期强度要求高的特点,通过对冷再生混合料的级配构成、乳化沥青的优选及无机结合料的优选,引入高粘乳化沥青和石灰,制备出了具有良好早期强度和路用性能的冷再生混合料,并通过实体工程对结构补强效果进行了跟踪监测,验证了冷再生混合料对结构补强的适用性。
