Abstract

Road service quality can be determined by qualitative assessment (safety and comfort). The quality of the surface layer is one of the parameters. The HRS Base hot mix asphalt surface course, for example, is often a product failure. One of the reasons is the mismatch between the design results and the production of the mixture, for example, the gradation of mixed aggregates whose composition may deviate due to weaknesses in the production process at AMP. The first variation (10% more coarse aggregate) did not meet the specifications because there were several parameters that did not meet the requirements, namely VIM, VFB, MQ, and residual marshall stability, the second and third variations (10% less coarse aggregate and 10% more fine aggregate) the parameter values of VIM, VFB, MQ and residual marshall stability did not meet the specification requirements and only the parameter values of stability and VMA met the specifications. In the fourth variation (10% less coarse aggregate and 10% more fine aggregate), some of them met the specifications but there were two marshall parameter values that did not meet the specifications, namely the MQ value and the residual marshall stability, while in the control variable all the marshall parameter values met the specification requirements

Abstract

The selection of local materials in the manufacture of concrete always sought to be used for the convenience of the manufacturing process and the availability of materials. The local material must refer to the terms and conditions that meet the achievement of the expected concrete quality. In this study, materials originating from the Noemuti Quarry, TTU Regency, namely fine aggregate and coarse aggregate, were used as concrete constituent materials with a planned compressive strength target of 25 MPa. Cylindrical specimens with a diameter of 15 cm and a height of 30 cm were made and treated for testing to the compressive strength of concrete. The results of the material characteristics test showed that the fine and coarse aggregates fulfilled the terms and conditions of concrete constituents. The results of the unit weight test show that the concrete is included in the normal concrete category because the unit weight obtained ranges from 2200 – 2500 kg/m³. The result for the compressive strength test of the concrete, aged 7 days, obtained a compressive strength of 22.65 MPa. For ages 21 days, the compressive strength of concrete is 25.42 MPa, and for ages 28 days, it reaches 26.67 MPa. Thus, the aggregate from the Noemuti Quarry, TTU Regency, both fine and coarse aggregate, is suitable for making normal concrete with a compressive strength of 25 MPa.
