Freeze-thaw damage is the most common disease of semi-rigid bases in cold regions, which may greatly affect the durability of roadways. In this study, the compressive strength and frost resistance of four different types of semi-rigid bases(lime-fly ash-stabilized sand, cement-stabilized sand, lime-fly ash-stabilized gravel, and cement-stabilized gravel) are assessed by varying the materials content. Based on freeze-thaw and compressive strength tests, this paper presents the performance of the different materials, each having different physical properties, and the optimal amounts of materials contents are proposed.

识字是小学语文的基础，但是许多教师在识字教学中，教学方式单一，多采用反复抄写、机械记忆的方式，而且对于生字，他们只注重写，而忽视识，教学内容枯燥乏味，导致小学低段识字教学效率低下。基于此种教学现象，教师要善于将多媒体融入到识字教学中，不断激发学生识字兴趣，提高小学低段识字教学效率。一、合理使用多媒体，设计趣味性识字教学活动 教学中，教师要遵循小学生的身心特点，充分发挥多媒体的优势，为学生设计趣味
