digunakan adalah lapis AC-WC (Asphalt Concrete-Wearing Course). Sedangkan filler yang digunakan adalah filler debu batu dan debu kapur. Penelitian ini bertujuan untuk mengetahui nilai kekesatan lapis aus AC-WC setelah digesek (polish) sebanyak 0, 500, 1000, 1500, 2000, dan 2500 putaran. Penelitian ini dilakukan dengan cara membuat benda uji yang terdiri dari dua variasi yaitu benda uji campuran AC-WC filler debu batu dengan filler debu kapur. Dimana setiap variasi terdiri dari lima benda uji sehingga total benda uji sebanyak 10 buah. Selanjutnya dilakukan pengujian kekesatan dengan alat British Pendulum Tester (BPT) dan alat uji keausan modifikasi pada putaran 0, 500, 1000, 1500, 2000, dan 2500 putaran. Berdasarkan pengujian tersebut didapatkan perbandingan nilai kekesatan antara filler debu batu dengan filler debu kapur. Hasil penelitian menunjukkan bahwa nilai kekesatan (BPN) benda uji filler debu batu adalah 73,4 ; 69,6 ; 66,4 ; 61,6 ; 57,4 dan 54,2. Sedangkan pada benda uji filler debu kapur adalah 72,2; 68,4 ; 65,6; 60,2 ; 55,6; dan 52,6. Selisih nilai kekesatan antara kedua benda uji tidak terlalu besar sehingga filler debu kapur bisa menjadi alternatif pengganti filler debu batu. Kemudian tingkat keausan maksimum (putaran maksimum) benda uji filler debu batu adalah 4080 rotasi sedangkan pada benda uji filler debu kapur adalah 3445 rotasi.

Surface roughness of road pavement can affect the safety and convenience of road users. During this time, to know the value of a road roughness is only done when the new pavement. Therefore, it is made the modifications skid resistance tester which is a simulation of the real situation in the field, but can not predict the exact value of roughness according to the real situation on the highway because a test tool just polishing the surface of the specimens. Wearing layer used is AC-WC layer (Asphalt Concrete-Wearing Course). While the fillers used are stone dust and lime dust. This research aims to determine the value of skid resistance AC-WC surface layer after polished as much as 0, 500, 1000, 1500, 2000,and 2500 rounds. This research was carried out by making the specimens, which consisting of two variations of specimen, are AC-WC mixture stone dust filler and lime dust filler. Where each variation consists of five specimens, so the total of specimen are 10 specimens. Then, it is done a skid resistance test with the British Pendulum Tester (BPT) and modification skid resistance tester at 0, 500, 1000, 1500, 2000, and 2500 rounds. Based on these tests was obtained skid resistance value comparison between the stone dust filler and lime dust filler. The results showed that the skid resistance value (BPN) from specimens of stone dust filler are 73.4, 69.6, 66.4, 61.6, 57.4 and 54.2. While the specimens of lime dust filler are 72.2, 68.4, 65.6, 60.2, 55.6, and 52.6. Difference of skid resistance value between two specimens is not too large so that the lime dust filler can be an alternative to subtitute stone dust filler. Then the rate of maximum roughness (maximum spin) specimen of stone dust filler is 4080 while the specimen of lime dust filler is 3445 rotations.
