基于振动能量的新型高速公路压路机集成压实监控指标研究
Research on new roller-integrated compaction monitoring index of highway based on maximum positive kinetic energy increment
摘要
Abstract
In response to the shortcomings of the existing roller-integrated compaction monitoring indexes of highway,the energy conversion law between the vibration wheel and the filling materials within a single cycle was analyzed,and an integrated compaction monitoring index kinetic energy compaction value(KECV)based on the maximum positive kinetic energy increment was proposed,and compared with the existing index compaction power per unit volume E,its effectiveness was verified.Combining with the law of conservation of energy,the energy exchange during compaction was reflected by the variation characteristics of the positive kinetic energy,and the maximum positive kinetic energy increment was used as roller-integrated compaction monitoring index to determine the compaction status of the filling materials.The correlation between KECV and compactness K of subgrade silt,as well as between KECV and relative density Dr of pavement cement-stabilized macadam were respectively established.The results show that as the number of compaction passes increases,the maximum positive kinetic energy increment also gradually increases and the filling material changes from loose to dense.The correlation coefficients between KECV and compactness K of subgrade silt,as well as between KECV and relative density Dr of pavement cement-stabilized macadam are all greater than that of E,indicating that the proposed index KECV is feasible in controlling the compaction quality of subgrade and pavement.关键词
