Forth Road bridge is a suspension bridge with a main span of 1006 metres and side spans of some 408 metres. Approach viaducts to the north and south bring the total length of the structure to just under 2500 metres. The bridge was opened in 1964 and traffic has grown significantly from 4 million to 24 million vehicles using the bridge each year. All work carried out on the bridge has to be don…
Uji coba skala penuh teknologi Cakar Ayam Modifikasi (Cakmod) pada daerah tanah lunak yang sangat tebal di Pantura Km 25+ s.d 26+ terdiri dari dua tipe. Hasil monitoring menunjukkan: 1) Setelah 13 bulan, Tipe 1 cakmod dengan lapisan permukaan slab beton yang ditambah lapis aspal secara visual menunjukkan kinerja yang masih baik belum tampak retak refleksi, sedangkan hasil core telah terjadi ret…
This paper present a microstructure-based finite element model by incoerporating elastic aggregrates and vicoelastic sand mastic. The microstructure-based finite element (FE) approach was used to predict the linear and damage-coupled viscoelastic properties of reclaimed asphalt mixture. The two-dimentional (2D) microstructure of asphalt mixture pavement (RAP) mixture specimen. In the microstruc…
Prediction models for pavement deterioration of major roads in Miyazaki Pre-fecture, Japan, using falling weight deflectometer (FWD) data are presented. The models would be incorporated in a pavement management system (PMS), for the prefecture, which is under development. At first, a relation between Japanese maintenance control index (MCI) and cumulative equivalent single axle loads (CESAL) wa…
