随着我国高速公路的迅速发展,对铺筑高速公路所需要的筑路设备提出了更高的要求。高速公路建设底基层最常用的材料是粘土,粘土是一种料源较广泛且成本较低的材料,但粘土也有其自身存在的缺点:受天气影响较大,含水量不均匀,透水性差,碾压后易出现软弹、开裂。常用的灰土搅拌设备采用普通灰土拌和站,在粘土中掺入白灰、水泥等添加剂,用以改善土的性能,改善土的天然稠度。普通灰土拌和站
With the rapid development of the expressway in our country, higher requirements are put forward for the road construction equipment required for paving the expressway. The most commonly used material of the subbase of expressway construction is clay. Clay is a material with a wider source and lower cost. However, clay also has its own shortcomings: it is affected by the weather, uneven water content, poor water permeability, Easy to appear after rolling soft bullets, cracking. Commonly used lime soil mixing equipment using ordinary lime mixing station, in the clay mixed with lime, cement and other additives, to improve the performance of soil, improve the natural consistency of soil. Ordinary ash mixing station
