Abstract The technology of vibratory mixing has been applied to improve the compressive strength cement-stabilized macadam (CSM). aim this study is investigate effect vibration acceleration and cement dosage on unconfined density CSM. mixtures with four dosages (2%, 3%, 4%, 5%) were prepared by conventional (0 g) (1 g, 2 3.5 g). was tested under different methods. And microstructure CSM analyze...

There are a large number of high liquid limit soil distributed in southern China. As one of the special soils commonly seen in highway construction, high liquid limit soil cannot be used in subgrade filling directly due to its special engineering properties. With the idea of saving engineering investment and protecting environment, high liquid limit soil must be improved to be qualified subgrad...

The pavement constructions on soft and expansive soils are not durable and unable to sustain heavy traffic loading. As a result, pavement failures and settlement problems will occur very often even under light traffic loading due to cyclic and rolling effects. Geotechnical engineers have dwelled deeply into this matter, and adopt various methods to improve the engineering characteristics of sof...
