摘　　要：近１０年来，我国高速公路建设正在蓬勃发展，至今已建成高速公路２５００ｋｍ，高速公路的路面，９０％以上是半刚性基层沥青路面，半刚性基层所用材料既有水泥级配集料和密实式石灰粉煤灰级配集料，也有水泥石屑和悬浮式石灰粉煤灰集料。我省近年来修建的高速公路，其路面基层９５％左右都采用水泥稳定砂砾作为沥青路面的半刚性基层，它以特有的强度高、稳定性好、便于施工等优点，而被广泛使用。Ln recent 10years,the expresway Constrution im wr Country is deueloping Vigorousty,up to now,the Conpleted expressway is up to 2500km,95%of Expressway pavemtnt adopted asphalt pwemenf of half-rigid bese.The material in helf-rigid bese are cement graded aggreyate and dense Lime coalah graded agyregafe,and Cemenf Sfone chip and suspension Lime coal ash aggregate.Aborf 95% of Pauemenf base adopted the Cement stabilized sand and gravel as a half-riyid base of asphalt pavement in recenf Constyucfing Expressway in our provincl,and it woas used widly as high sfcengch,sfabilizafion and easy to Constructing.
