热拌沥青混合料的施工质量在很大程度上决定了沥青混凝土路面的最终路用性能,保证施工质量是提高道路服务水平和使用寿命的关键。采取分批次质量检查验收的方式,将施工质量与支付调整挂钩,能够激励施工单位提高工程质量,避免不合格产品。在国内外已取得研究成果和经验的基础上,结合国内实际情况,提出了基于经验法的热拌沥青混合料施工质量支付系数计算框架,并推荐了计算系数。
The construction quality of hot asphalt mixture largely determines the final road performance of asphalt concrete pavement, and ensuring construction quality is the key to improve the service level and service life of road. To take a batch of quality inspection and acceptance of the way, the construction quality and payment adjustments linked to the construction unit can be motivated to improve the quality of the project to avoid substandard products. Based on the research achievements and experiences both at home and abroad, combined with the actual situation in our country, a calculation framework of the construction quality payoff coefficient of hot mix asphalt based on empirical method is proposed and the calculation coefficient is recommended.
