刚性道面冻害的产生,几乎全是由于路基不均匀冻胀造成的。以往对刚性道面路基处理时,没有完全针对这个特点。有时是套用了柔性道面实质上是增强路基形变模量的处理方法,结果不能令人满意。下面介绍几种处理方法的效果及笔者的分析,供有关同志参考。一、用非冻胀性材料加厚人工基础 Rigid road frost damage, almost entirely due to uneven subgrade frost heave caused. In the past when dealing with rigid pavement subgrade, this feature was not completely addressed. Sometimes the application of a flexible pavement is essentially a way of enhancing the modulus of deformation of the roadbed. The result is unsatisfactory. The following describes the effectiveness of several treatment methods and the author’s analysis for the comrades for reference. First, with non-frost heave material thickened artificial base
