上面层SMA-13改性沥青混合料进行目标配合比设计
一、概述
　　受某公司委托，江苏省交通科学研究院负责对某标上面层SMA-13改性沥青混合料进行目标配合比设计。
二、设计依据
1.《公路沥青路面施工技术规范》（JTG F40-2004）
2.《公路工程沥青及沥青混合料试验规程》（JTJ052-2000）
3.《公路工程集料试验规程》（JTG E42-2005）
三、原材料
　　本次目标配合比设计所用集料为河南桐柏石料场玄武岩；沥青为重庆美仑SBS改性沥青；纤维为松散木质素纤维（用量为沥青混合料总重量的0.3%）；抗剥落剂用量为沥青重量的0.4%。本次配合比设计所用原材料均由施工单位送样。
　　各种集料、矿粉及沥青的密度试验结果见表3-1和表3-2、各种矿料及矿粉的筛分结果见表3-3。
