Indonesia memiliki kekayaan sumber alam yang tinggi, termasuk sumber mineral yang menjadi bahan baku perkerasan jalan. Pemanfaatan sumber alam berupa bahan baku perkerasan jalan masih belum banyak dikembangkan, terlebih kaitannya untuk mengatasi permasalahan kerusakan dini pada perkerasan jalan. Aspal Pen. 60/70 dan zeolit alam merupakan salah satu kekayaan alam yang bisa digunakan, namun penelitian terkait kedua bahan tersebut masih belum banyak dilakukan. Penggabungan kedua bahan dalam pengujian dilakukan dengan perancangan benda uji menggunakan 5 variasi kadar filler, yaitu variasi 1 (100% debu batu : 0% zeolit alam), variasi 2 (75% debu batu : 25% zeolit alam), variasi 3 (50% debu batu : 50% zeolit alam), variasi 4 (25% debu batu : 75% zeolit alam) dan variasi 5 (0% debu batu : 100% zeolit alam). Setelah diperoleh kadar aspal optimum setiap variasi kemudian dilakukan pengujian Marshalldengan lama perendaman 0,5 jam dan 24 jam,kemudian pengujian Indirect Tensile Strength. Hasil penelitian diperoleh kadar aspal optimum untuk variasi 1 sebesar 5,8%, variasi 2 sebesar 6,0%, variasi 3 sebesar 6,1%, variasi 4 sebesar 6,4% dan variasi 5 sebesar 6,5%. Nilai VMA, VITM, VFWA, stabilitas, flow, MQ, indeks stabilitas Marshallsisa dan rasio kuat tarik secara berurutan untuk variasi 1 sebesar 16,04%; 4,53%; 69,56,82%; 1229,05 kg; 3,80%; 323,43 kg/mm; 94,46%; 74,87%, variasi 2 sebesar 14,69%; 4,74%; 68,02%; 1348,40 kg; 4,27%; 316,03 kg/mm; 92,06%; 79,92%, variasi 3 sebesar 16,14%; 4,41%; 69,69%; 1364,69 kg; 3,93%; 346,95 kg/mm; 89,64%; 72,75%, variasi 4 sebesar 16,89%; 4,82%; 69,31%; 1304,30 kg; 4,03%; 326,07 kg/mm; 88,04%; 68,82% dan variasi 5 sebesar 16,42%; 5,18%; 64,55%;1248,64 kg; 4,5%; 277,48 kg/mm; 86,78%; 66,22%. Dari hasil tersebut menunjukkan bahwa campuran AC-BC yang menggunakan zeolit alam pada variasi 2 (75% debu batu + 25% zeolit alam) dan variasi 3 (50%debu batu + 50% zeolit alam) merupakan komposisi yang optimum dalam menggunakan zeolit alam sebagi filler.

Indonesia has a wealth of natural resources is high, including mineral resources into pavement materials. Utilization of natural resources such as raw materials pavement still has not been developed, especially to overcome the problems related to premature pavement damage. Asphalt Pen. 60/70 and natural zeolite is a natural asset that can be used, but the study linked the two materials are still not widely practiced. Merging the two materials in the testing done with the design of the test specimen using 5 filler content variation, the variation of1 (100% stone dust: 0% natural zeolite), variation 2 (75% stone dust: 25% natural zeolite), variation 3 (50% stone dust: 50% natural zeolite), variations4 (25% stone dust: 75% natural zeolite) and variation 5 (0% stone dust: 100% naturalzeolite). Having obtained the optimum bitumen content of each variation then testing Marshall with soaking time of 0,5 hours and 24 hours, then the Indirect Tensile Strength testing. The results were obtained for the optimum bitumen content variation 1 is 5,8%; variation 2 is 6,0%; variation 3 is 6,1%; variation 4 is 6,4% and variation is 6,5%. Value of VMA, VITM, VFWA, stability, flow, MQ, Marshall stability index and the residual tensile strength ratio in sequence for variations 1 is 16,04%; 4,53%; 69,56,82%; 1229,05 kg; 3,80%; 323,43 kg / mm; 94,46%; 74,87%; variatioun 2 is 14,69%; 4,74%; 68.02%; 1348,40 kg; 4,27%; 316,03 kg / mm; 92,06%; 79,92%; variation 3 is 16,14%; 4,41%; 69,69%; 1364,69 kg; 3,93%; 346,95 kg / mm; 89,64%; 72.75%; variation 4 is 16,89%; 4,82%; 69,31%; 1304,30 kg; 4,03%; 326,07 kg / mm; 88,04%; 68,82% and variation 5 is16,42%; 5,18%; 64,55%; 1248,64 kg; 4,5%; 277,48 kg / mm; 86,78%; 66,22%. From these results indicate that the AC-BC mixture that uses natural zeolite on variation 1 and variation 2 has a good durability than 3.4 and 5.Dan variations for optimum levelsof zeolite were used as the filler is on the variation of 2 (75% rock dust + 25%natural zeolite) and the variation of 3 (50% stone dust+ 50%natural zeolite).
