| 摘要： | Traffic loading stress in highway subgrade is useful information pertinent to pavement structures during construction stages. Five subgrade sites on Louisiana's highways were instrumented with soil pressure cells to measure the additional soil stresses induced by construction machinery and moving vehicles at different construction stages. Measured soil pressures in duced by compaction machinery appear to be much larger than anticipated working stress levels caused by inservice traffic. Stress levels generated by compaction machinery may play an important role in selecting suitable pavement materials. Such measurements also provide insights into the stress histories of pavement materials and make themselves valuable in numerically modeling the behavior of pavement layers. |
