Abstract

Abstract The condition of bonding between asphalt pavement layer can influence the behaviour of pavement structure in supporting vehicle loading. In strong bonding condition, the adjacent pavement layers will act together to support pavement loading and the other way in weak bonding condition the layers will act independently with the result that stress in every layer of pavement become higher and will decrease pavement life consequently. This study described the investigation of bonding condition using teorethical model and laboratory test. Those are developed using CIRCLY5-SAP2000 Program and Modified Direct Shear Test respectively. The results shown that there is the range of bonding parameter which starting from weak bonding until full bonding using theoretical and laboratory model. Futhermore the analysis shown that ignoring bonding condition between pavement layer will become one of factors which cause early damage in pavement structure.Keywords : Bonding, Direct Shear Test, SAP2000, CIRCLY5

Abstract

Belok Kiri Langsung (BKL) pada saat lampu lalu lintas menyala merah or Left Turn on Red (LTOR) on any road intersection is now confusing some drivers in this country who do not know or have never known the traffic related regulation. Indonesian Road Traffic and Transportation Law (UU No. 15/1992) with its Goverment Decrees established and issued by the President concerning the Infrastructure and Road Traffic, Peraturan Pe,erintah (PP) No. 43, 1993, article 59 paragraph 3 says that vehicles in any approach which has an LTOR sign displayed may turn left after stopping, providedit is safe to do so. The Indonesian Road Traffic and Transportation Law, UU No. 14/1992 and PP 43/1993 art. 59 p(3) provides the authority for its use. The following problem arises, that the BKI, can not be done safely on any road intersections. Many intersections have geometry deficiencies, such as lack of channelisation, lack of turning lanes, absence of sidewalks and insufficient intersection areas. On the road ontersection within the Area Traffic Control System (ATCS), this problem becomes more difficult since LTOR is not only involves in installing traffic signs, but modification on controler and detector which affect the lanes presence timed calls may required before LTOR is permitted.
