PURPOSES : The purpose of this study is to present a cross section suitable for low-traffic road pavement considering the environmental characteristics of Vietnam.
METHODS : The behavior of the pavement with respect to the axial load was numerically analyzed using the nonlinear finite element method. The elastic-plastic material model was applied to material properties such as subgrade, sub-base layer, and base layer, and whether the material yielded was determined. In order to evaluate the adequacy of the cross section of the Vietnamese low-traffic pavement, it was compared with the KPRP Lv 3 road pavement section. And it was compared with the newly proposed MAST composite Pavement. The design life of each pavement section was calculated using the results obtained from the pavement structural analysis.
RESULTS : The cross section of the Vietnamese low-traffic road pavement, KPRP lv3, MAST composite Type1 road pavement did not satisfy the design criteria for fatigue cracking and rutting. MAST composite Type2 was analyzed considering CTAB having 100mm and 150mm thickness and compressive strength of 5MPa, 10MPa, 15MPa and 20MPa, and all of them satisfied the design criteria.
CONCLUSIONS : The low-traffic road pavement section in Vietnam currently used is judged to be inappropriate, and the MAST Composite type 2 proposed in this study is evaluated as an appropriate alternative. Further studies such as field application are needed in the future.
