Abstract

In genelar, defect in the flexible pavement on road links which heavy loaded traffic and have high temperature is plastic deformation. This paper discusses some causes of plastic deformation occurred in the field and some factors that effect occurring plastic deformation. Plastic deformation found in the field is effect of bad design gradation and of high bitumen content as caused mix design without void in mix at refusal density. Plastic deformation with rut depth is less than 20 mm, displacement or shear occurred on the wearing course (ACWC). In spite of rut depth is more than 20 mm, displacement or shear also occurred on the second layer or binder course (ACBC). Base on rut depth above, so we can used as a guide for determining of asphalt layer is should be scraped or repaired. Giving attention for example to consider void in mix at refusal density on mix design and the uses of asphalt mixtures which relatively high stiffness can reduce plastic deformation.Keywords: flexible pavement, plastic deformationPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3896[How to cite: Nono dan Yamin, R.A., 2005, Study Kasus Deformasi Plastis, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 1, pp. 48-59]

Abstract

Asphalt polymer has superior characteristics than conventional asphalt. Styrene Butadiene Styrene (SBS) is a polymer that has proven its performance in heavy traffic, but it must be imported and expensive. Crumb rubber have high potential to be used as an asphalt modifier. Asphalt modified crumb rubber has high viscosity and is not homogeneous, so that the utilization cannot be delayed. This reduces workability in the field. This study aims to obtain asphalt modified crumb rubber which is easier to use by adding materials that do not affect its performance. RejIRE is a low viscosity additive to restore the properties of bitumen on crumb rubber modified. Experiments were carried out by adding variations in RejIRE levels to crumb rubber modified asphalt to determine its characteristics. Continued investigation of the performance of hot paved mixtures for wearing courses compared to asphalt mixtures with Pen 60/70 asphalt and SBS modified asphalt mixtures. The result is the addition of 0.75% RejIRE on asphalt crumb rubber modification have high workability. Overall the performance of the mix with SBS modified asphalt is better, but the mixture of hot paved with modified asphalt crumb rubber has a resistance to permanent deformation superior to the other paved mixtures.
