چکیده مقاله
Providing adequate drainage to a pavement system is an important design consideration to prevent premature failure due to water related problems such as pumping action, loss of support and rutting This study focuses on subsurface drainage issues in Iran Evaluation parameters for subdrainage are traffic load, permeability coefficient of subgrade, freezing index and annual precipitation The last two are climatic parameters used in the procedure proposed in this paper The time to drain method was used to evaluate subdrainage efficiency SH DRAIN' Software was developed to facilitate pavement subsurface drainage design
