PERENCANAAN PERKERASAN KAKU (RIGID PAVEMENT) PADA RUAS JALAN NGRANCAH KULON – MUSUK KABUPATEN BOYOLALI DENGAN METODE AASHTO 1993
Pavements are part of the path and structural part of the road the transverse part of the most central road structure. Pavement structure can be divided into several pavements such as bending pavement, rigid pavement, and composite pavement. The planning data research was taken from the Ngrancah Kulon - Musuk road section of Boyolali Regency, including the Average Daily Traffic (LHR) containing traffic calculations passing through the Ngrancah Kulon - Musuk road. The Dynamic Cone Penetrometer (DCP) test to determine the value (CBR) of the California Bearing Ratio was carried out as many as 10 points of 200 meters test distance from STA 0+000 – 2+000 on the Ngrancah Kulon - Musuk road section. Rainfall data is obtained from the Central Statistics Agency (BPS) of Boyolali Regency. Based on the analysis of the data obtained, it was concluded that the planning of the Ngrancah Kulon - Musuk road structure uses rigid pavement, for this planning method using the AASHTO 1993 method. After calculations were obtained rigid pavement thickness 200 mm with a bottom foundation layer (lean concrete) 70 mm, the need for longitudinal and transverse reinforcement Ø10 – 250 mm, dowel Ø25 - 300 mm length 450 mm, tie bar D 16 mm - 1200 mm (thread) length 800 mm, planning drawings were applied using autocad based on the calculations obtained. The results of the Cost Budget Plan (RAB) obtained a required cost of Rp. 5,650,761,000.00 (Five billion six hundred fifty million seven hundred sixty-one thousand rupiah).
