Abstract

PT Inti General Yaja Steel Semarang is a company engaged in the metal industry, from the production activities produced waste iron slag in large quantities. On the other hand the availability of materials in the manufacture of paving blocks that are natural resources will over and can not be updated, this problem will be sought alternative replacement. The purpose of this study is the utilization of iron slag waste as a substitute of some fine aggregates in the manufacture of paving blocks, to find out the maximum compressive strength and the most efficient production cost among the mixture 1Pc : 6Ps (standard); 1Pc : 5Ps : 1Tb; 1Pc : 4Ps : 2Tb; 1Pc : 3Ps : 3Tb; 1Pc : 2Ps : 4Tb; 1Pc : 1Ps : 5Tb. Paving blocks made with size (21 x 10.5 x 6) cm. Based on the average 28-day estimate, standard paving blocks have a compressive strength of 204.09 kg/cm2, the maximum compressive strength is in the mixture of 1 PC: 3 PS: 3 TB of 335.28 kg/cm2, an increase of 64.28% of the standard paving block. While the minimum compressive strength is in the mixture of  PC: 1 PS: 5 TB of 95.89 kg/cm2, decreased 4.02% compared to standard paving blocks. When reviewed based on production costs, the standard paving block has a production cost of Rp 1.004,29. A mixture of 1 PC: 3 PS: 3 TB has a production cost of Rp 974,29 decreased 2.99% when compared to standard paving blocks. The most cost  fficient production mix is 1 PC: 1 PS: 5 TB of Rp 894,69. Reduced by 10.91% of standard paving blocks.Kata kunci : compressive strength, paving block, iron slag

Abstract

The road is the basic infrastructure and major in propelling the national economy and local governments, considering important and its strategic function of road to push the distribution of goods and services as well as the population mobility. It is necessary for planning the structure of his stardom is a strong, durable and have a high durability against plastis deformation. As a indication factor if the cause of the overload or often called Physical Damage factor (P.D.F.), load repetition and drainage function less well. The third factor is the main cause of damage to road roughness is demanding the use of the material for the road roughness with better quality, in the form of aggregate materials as fillers are primarily asphalt or as a binder. This research was conducted to measure up to abaout performance of the asphalt Pertamina Pen 60/70 and BNA Blend 75/25 on hot mix asphalt AC-WC to the characteristics of the Marshall and the results are expected to provide information in the field of street work. The results showed that the value of the characteristics of Marshall on the optimum asphalt content (OBC), the mixture of the Laston AC-WC using BNA Blend 75/25 (mixture “B”) has better characteristics than the Laston AC-WC using asphalt Pertamina Pen 60/70 (mixture “A”). Shown with Marshall Stability on mixture “B”amounted to 1088.621 kg higher than the mixture “A” amounted to 891.902 kg. Marshall Quotient (MQ) value mixture “B” amounted to 327.86 kg/mm higher than the mixture “A” amounted to 284.98 kg/mm, can be interpreted as indicating a high ability of MQ receive traffic load repetition, friction wheels of vehicels on the road surface and the ability to withstand wear and tear due to the influence of temperature changes. From these results reinforce answered the initial hypothesis that the BNA Blend 75/25 is more durable than asphalt Pertamina Pen 60/70.

Abstract

Road roughness layer construction work in Indonesia as long as this concern, i.e. damaged before age plans, although not all of these statements are valid in General. As an indication of overload or cause factor is often referred to by Physical Damage Factor (P.D.F.), time loaded and environmental change or the drainage function is not optimal. All three of these factors as the cause of the occurrence of the damage. The use of a material with a better quality of aggregate gradation of mainly filler material as well as asphalt binder material, as well as planning, quality of execution and how strict scrutiny. This research was conducted to measure up to the temperature influence of roughness asphalt macadam on the mixture of hot mix asphalt AC-WC using hard asphalt (Asphalt Pen 60/70) about Marshall characteristics and the result expected can provide information of Department of Public Work. In the study done of making test with variations in soaking temperature for analyzing how performance degradation when soaking temperature paved mixture does not fit standard (standard temperature of 60° C).
