河北平原地区缺乏砂石材料,利用石灰稳定土壤作路面承重层已被广泛采用。近两年来为进一步寻求合理的结构形式,我们在生产中用石灰稳定低塑性土壤。通过施工中的一些实践和观测,有以下几点体会: 一、通过实践我们认为任何土壤都能用石灰来稳定作为路面承重层,只是强度有所差异。在平原地区利用灰土做路面其经济指标是主要目的。1964年我们在津保线由于沿线缺乏粘土,如进行远运粘土,不但要加大造价,而且多占用粘土地,与农业生产发生很大
The lack of sand and gravel material in the Hebei Plain, the use of lime stabilized soil as the bearing layer has been widely used. In the past two years in order to further seek a reasonable structure, we use lime to stabilize low plasticity soil in production. Through some practices and observations in construction, the following experience: First, through practice, we think that any soil can be stabilized with lime as a road bearing layer, but the intensity varies. Using plain soil as a pavement in plain areas has its main objective of economic indicators. In 1964, due to the lack of clay along the route, such as carrying long-distance clay, we not only increased the cost, but also occupied more clay and had a great deal of agricultural production
