摘要
采用三种配比的水泥稳定钢渣混合料铺筑了G65包茂高速上基层试验段,测试了现场拌和混合料的含水率和水泥剂量以及标准试件的7 d无侧限抗压强度,同时测量了试验段路面的压实度、平整度和弯沉值.结果表明,三种钢渣混合料的7 d无侧限抗压强度均高于9.0 MPa,水泥用量更少的全钢渣混合料的强度略高于水泥用量为4.5%的部分钢渣混合料组.试验段的压实度满足规范要求,其平整度平均值均小于2 mm,弯沉代表值为23.20(0.01 mm).试验段的整体路用性能良好.
The G65 Baomao high-speed upper base test section was paved with cement stabilized steel slag mixture of three proportions.The moisture content and cement dosage of the on-site mixing mixture and the 7-day unconfined compressive strength of the standard specimen were tested.Meanwhile,the compaction degree,smoothness and deflection values of the pavement in the test section were measured.The results show that the 7-day unconfined compressive strength of the three steel slag mixtures is higher than 9.0 MPa,and the strength of the whole steel slag mixture with less cement content is slightly higher than that of some steel slag mixture groups with 4.5%cement content.The compaction degree of the test section meets the specification requirements,the average flatness is less than 2 mm,and the deflection representative value is 23.20(0.01 mm).The overall road performance of the test section is good.
