Road base coarse construction requires a foundation that must be sufficient to carry the vehicle load on the subgrade. Therefore the upper foundation layer is very directly influential on the burden received by the pavement layer. Limestone is an alternative innovation for the aggregate base coarse foundation. Based on the method of this research, an experiment was carried out to determine the aggregate test and the strength value of Limestone as a mixture of the upper foundation layers on the pavement. The cornerstone of the testing theory uses the 2010 Bina Marga General Specifications method, with the percentage of Limestone as a gross aggregate of 5%, 10%, 15%, and 20%. The number of samples used for each variation is five pieces. The test results show that a mixture of 10% limestone is the optimum result. The abrasion test showed a resistance of 25.63% and an area of 81.53% rupture. In the LL test results showed a value of 12%, IP 6.1%, CBR Soaked 94%, ɣd 2.43 gr/cm3, and W valued at 5.69 gr. Thus Limestone can be used as a combination of upper foundation layer material on road pavement.
