PENGGUNAAN IRON SLAG SEBAGAI AGREGAT KASAR PADA CAMPURAN HRS-WC

Abstract

Aggregate with good qualities and traits needed for pavement directly bear the burden of traffic and pass kelapisan that are below. In the reality on the ground there are certain areas that are difficult to get a standard aggregate for pavement materials, an alternative to the road pavement is utilizing local materials as an example; iron slag aggregate. The research method is a method in laboratory experiments is making mix asphalt aggregate HRS-WC replace the standard 10-20 aggregate mm and 0,5-10 melly meter iron slag. Testing is done by making 12 specimen to obtain the optimum bitumen content at 7.4% and then made again 20 sample that used iron slag with variation 0%, 25%, 50%, and 100% of the values obtained result of marshall Stability, Flow, VIM, VMA and Marshall Quotien between standards and iron slag aggregate experience increase in line with the prevailing usage iron slag while VFB value, density, Film and Thick Asphalt between standard aggregate and iron slag decrease with the size of the use of iron slag. Marshall test soaking the rest of 30 minutes and 24 of the results Obtained the highest value of the remainder marshall 92.26 % on variations 100 % iron slag . Aggregate iron slag aggregate the which meet the requirements of the standard (specification of Highways Ministry of Public Works 2010 Revision 3) can be used to aggregate asphalt mixture
