To handle roads that have a subgrade with a CBR (California Bearing Ratio) of less than 2% and a plasticity index of more than 20%, one of them is by using CTB (Cement Treated Base) pavement on the foundation layer. CTB is a mixture of materials consisting of coarse aggregates, fine aggregates, cement, and water. Periodic maintenance of roads in the southern part of West Java Province uses a pavement structure that is, AC-WC as a surface layer, CTB as the upper foundation layer, class A aggregate, as the lower foundation layer. Based on the contract time calculation, there will be a delay in the execution of the work, because the quary material is only 1 location and there is a build-up of mixing and mixing of coarse and fine aggregates to meet the mixture of CTB and class A aggregates. A is only one aggregate fraction so that in the quarry material only one time is made and mixed. Research on the nature and characteristics of the aggregate obtained results, namely the volume volume of the CTB mixture using a class A aggregate mixture: portland cement (1%), water (2.08%), fine aggregate (3.41%), and coarse aggregate (4.74%). While the results of the concrete compressive strength test on the mixture of CTB with CTB aggregate obtained an average compressive strength value of 127.70kg/cm2 greater than the planned compressive strength of 125kg/cm2. For CTB mixture using CTB aggregate, it becomes: Portland cement (1%), water (1.0%), fine aggregate (2.70%), and coarse aggregate (3.20%). While the concrete compressive strength test results on the mixture of CTB with CTB aggregate obtained an average compressive strength value of 126.80kg/cm2 greater than the planned compressive strength of 125kg/cm2. After modification of the pavement type, the road pavement structure becomes a surface layer with 4cm thick AC-WC, the upper foundation layer uses CTB with class A thick aggregate 20, the lower foundation layer with class A aggregate 20cm thick, and the original soil as a subgrade layer.
