Penentuan sifat kekukuhan dan ketebalan lapisan permukaan berasfalt menggunakan kaedah Pencarian Resonan Tambahan (ERS)

This study was conducted to investigate the stiffness and thicknesses of asphalt surface layer using the enhance resonance search (ers) technique. a total of fifteen locations in the universiti kebangsaan malaysia (ukm) campus have been identified to carry out this experiment. the results were then compared with standards provided by the malaysian public works department (pwd),jabatan pembangunan dan penyelenggaraan (jpp) ukm and kumpulan ikram sdn. bhd. the computation found that the range of elastic moduli values of asphalt layer is between 3928.877 and 17726.012 mpa. a comparison between the experiment results and jpp ukm standard on pavement thickness showed that the different is between 20% to 60%,with the average thickness of 44.13 mm. however,the average value of thickness is still in good agreement with the jkr and jpp ukm standards. some stiffness values obtained are higher than the standard,probably due to the quality of materials used,the influence of the traffic load and the age of the pavement construction. © 2015 penerbit utm press. all rights reserved.
