Dynamic compaction (DC) is one of the most popular methods for ground improvement. To solve problem factors affecting sandy soil improvement effect and estimate effective range under DC, influences drop number, energy, tamping distance, tamper radius, momentum on relative degree were investigated. Three normalized indicators △δz,i, △δA,i, △δU,i derived to evaluate weak zone corresponding effect...

pavement permanent deformations due to lack of shear strength in mixture are a major reason of rutting. any simple test to determine mixtures resistance to permanent deformation isn’t distinguished in the 1st level of superpave mix design method and prevalent methods for evaluating mixture rut resistance are expensive and time-consuming. two aggregate types, gradations, asphalt cements and fill...
