| Abstract: | The tests such as free swelling ratio, plasticity index, total rate of swelling-shrinkage and standard moisture absorption content of three typical types of soil in west Henan are carried on in order to distinguish their expansibility. Different soil is used in different layers of subgrade. At the same time, the geotechnical grille and impact compaction technology are method, construction technology and used to strengthen the expansive soil subgrade. Reasonable construction paving quality control measures are also proposed |

| Keywords: | expansive soil free swelling ratio maximum moisture absorption content plasticity index geotechnical grille impact compaction |
