前言为延长路面使用周期,降低养护成本,对路面结构型式曾作过多种探讨,希望采用强度高,稳定性好,耐久抗冻,使用时间长的路面结构。根据国外资料介绍及到日本考察的结果,认为钢纤维混凝土抗拉、抗弯、抗剪强度高,韧性、抗冲击性、抗裂能力大,抗冻融、耐疲劳、耐久性、稳定性均佳。特别是用于公路路面上,能减薄路面厚度,显著延长路面使用寿命。因此,在沈阳-营口线K25+650-750处,修建了100米钢纤维混凝土试验路面。以此做为提高我省公路路面质量,探索新途径。一、试验路段的划分为了探索理想的钢纤维掺入率,将100米试验路,分成四种不同的钢纤维含量,采用了8厘米厚钢纤维混凝土罩面,为今后黑
Preface To prolong the service life of pavement and reduce the cost of maintenance, various discussions have been made on pavement structure types. We hope to adopt pavement structure with high strength, good stability, durable frost resistance and long service time. According to the introduction of foreign materials and the results of the study in Japan, it is considered that steel fiber reinforced concrete has high tensile strength, flexural strength, high shear strength, high toughness, impact resistance and cracking resistance, anti-freeze-thaw resistance, fatigue resistance, durability and stability good. Especially for road pavement, can reduce the thickness of pavement, significantly extend the service life of pavement. Therefore, in Shenyang - Yingkou line K25 +650-750 Department, built 100 meters of steel fiber reinforced concrete test pavement. In order to improve the quality of highway pavement in our province, explore new ways. First, the test section of the division In order to explore the ideal steel fiber incorporation rate, the 100-meter test road, divided into four different steel fiber content, the use of 8 cm thick steel fiber concrete overlay for the future black
