One of the main factors affecting the settlement of road is vehicle load. This factor will be further supported in term of impacting more on road subsiding when the road are constructed on the soft clay. In regard with the middle district of Thailand, this part has the heavy traffic while most of this land consists of soft clays with the high depth ranging from 10 to 15 meters. Referring to this number its strength value is accordingly low and the compressibility value goes high. However, this problem has been improved by mean of a well-known technology of soil stabilization employing cement mixing to improve the engineering properties of soil which are the stability of strength and the settlement of soil. Although the soil property is strengthen, the test of soil's strength property which is an important part of road design is still tested under the static condition. In fact the vehicle load on the road is dynamic; therefore, it is unable to reach the actual strength property, settlement behaviour happened, and also the durable output using for calculation of road design. To approach the dynamic behaviour of soft clay this research is aimed at study the dynamic behaviour of both the soft clay mixed with cement 5% and the soft clay without cement. In this study the soft clay used is reconstituted to be similar to the soil in the central part of Thailand as much as possible and all specimens of cement admixed clay are prepared with liquidity index 1.0 and 1.5. Resulting from this investigation under the real loading form the outcome will lead to clearer comprehension of dynamic behaviour of soft clay and cement admixed clay meanwhile provide the virtual strength parameters of both kinds of clay studied. Moreover, as it is much closer to real condition, these parameters will be essential data employed for the efficient road design particularly in the central part of Thailand
