摘要：The aim of this study is to determine levels of cement that can be used for the top layer foundation (base course) with recycled asphalt materials mixed cement on road rehabilitation Semarang – Demak. T his study uses an experimenta l method in the laboratory with a cylindrical specimen diameter of 7 cm height of 14 cm made of cement content variation 0%, 1.5%, 3%, 4.5%, 6% and 7.5% is use d for testing the uncondifined compressive strength / (UCS) at the age of 7 days, 21 days, 14 days and 28 days. The results show that the addition of cement content w ill increase the value of the dry weight insignificantly, but will rise UCS value significantly and utilization of scratching asphalt cement with added material from these lab oratory experiments can increase the carrying capacity CTRB construction. Levels of cement that meets the requirements of Unconfined Compressive Strength (UCS) for the construction of Cement Treated Recycling Base (CTRB) is between 6% to 7.5%. Acc ording to the results of research it is economically to used cement content a t average of 6.75% for road rehabilitation works Semara ng - Demak has met the required UCS test.
