ABSTRACT
Margorejo road, Karangmalang district is one of the roads that has status as a district road in Sragen regency. The condition of the pavement on Margorejo road is bad, with the traffic volume and load of vehicles passing Margorejo road can be said as low, because it is only 228.8 vehicles/hour. In the next few years, a sports building will be established which will increase the volume and load of vehicles passing Margorejo road. This study is intended to evaluate the pavement of Margorejo road in serving the flow of vehicles both for the present and for the future. The existing pavement of Margorejo road will be evaluated based on Pt T-01-2002-B Bina Marga. This evaluation caried out using field CBR data with a DCP test, The existing surface course of Margorejo road is a 10 cm reinforced concrete, it needs 11,85 cm after the evaluation. Therefore, it is necessary to re-plan or increase Margorejo road pavement layer. With a small vehicle load, the author?s hypothesis about the cause of the damage to the pavement of Margorejo road is the poor composition of the layer. Without a base and a subbase course, thus soft particles from the subgrade course will go up to surface course, which will quickly reduce the life and strength of the pavement structure. In addition, the poor drainage in Margorejo road is also one of the causes.
