摘要
加州承载比试验是评价路基土和路面材料强度及稳定性的重要技术指标,对于路基填筑材料的合理选择具有重要的参考意义。全风化花岗岩残坡积土是工程建设中常碰到的土体类型,如何能更好的利用其力学性质指标,对于公路建设具有重要的意义。文章结合广东某高速公路项目,研究了全风化花岗岩路基填料掺砂后的CBR性质,并探讨了掺砂影响CBR值的机理。
strength. California bearing ratio is a technical judgment indicator of the intension of subgrade and pavement It is important to the selection of subgrade padding. Intense weathered granite residual soil is widely used in the construction and has an important meaning to take advantage of mechanical property for road construction. This paper investigates the CBR properties of intense weathered granite subgrade padding after being mixed into sand and discusses the mechanism based on a projcct of highway in Guangdong province.
