STUDI KOMPARATIF TEBAL LAPIS TAMBAHAN (OVERLAY) ANTARA METODE BINA MARGA DENGAN METODE AASTHO PADA RUAS JALAN PASAR CIAWI KECAMATAN CIAWI KABUPATEN TASIKMALAYA

Abstrak

The Cihanjuang - Ciawi road section, precisely Jalan Pasar Ciawi, is a district road that functions as a collector road with a road length of 2 KM. In general, the Cihanjuang - Ciawi road is in good condition, but at several points damage was found, either potholes or waves. High traffic flow and large traffic loads, so it must be balanced with good road pavement.

In this case, it causes congestion on the road section. To provide services to the community and for regional development, there must be development of transportation infrastructure as an effort to improve life both in the economic, social, cultural and other fields. Carrying out maintenance and improvement of transportation infrastructure on the Cihanjuang - Ciawi road section in Tasikmalaya Regency (Sta 000 + 000 - Sta 2 + 000) located in Ciawi District, Tasikmalaya Regency in the form of additional highway pavement (Overlay).

Data collection was obtained by conducting a field survey for 4 (four) days in one week, namely Thursday, Saturday, Sunday and Monday. Based on the calculation results of the planning of the thickness of the additional layer, several alternative pavement thicknesses can be taken by adjusting them to the soil conditions. However, technically, with the Bina Marga 1987 method, the pavement thickness is greater than using the AASTHO 1986 method. In this analysis, the thickness of the additional layer of the pavement with the Bina Marga 1987 method is 12.45 cm, while the AASTHO 1986 method is 6.4 cm. So that there is a significant difference with a difference of 6.05 cm. So that the thickness of the additional layer for the Cihanjuang - Ciawi Road section of Tasikmalaya Regency which is safe according to its planned age and implemented is the Bina Marga method with a thickness of 12.45 cm.
