<p>Abstrak. The Highway that connect Magelang Purworejo is one of the Collector roads in Central Java. Magelang-Purworejo’s Highway has a fairly high traffic load, based on a survey conducted by LHR in 2017 of 4392 vehicles. A high enough amount of LHR causes the road to damage the hair cracked. Based on the above, the thickness of the pavement or overlay is planned. This plan begins with a survey of the number of passing vehicles for twenty-four hours (LHR), then surveying the carrying capacity of ground using DCP tools, then measuring the skill of using digital teodholit. Then look for references and secondary data in the form of traffic growth, rainfall data and road class data. After all the data obtained then calculated the thickness of road pavement using the method of Bina Marga 1987. Based on these calculations obtained the required re-layer is 3 cm.</p><p><br />Key word: road pavement, overlay, dynamic cone penetrometer</p>
