Abstract

Roads have a very important role in advancing national development, structures made of concrete are very susceptible to cracking due to the brittle nature of the material and the nature of concrete that is strong against pressure, but weak against pulling. And the utilization of waste material as substitution of aggregate in concrete has been increasing nowadays. Therefore in this research, the use of silica sand and gravel from Indarung limestone waste were investigated. The purpose of this study is to determine the utilization of silica sand and gravel affect the compressive strength of the concrete as a substitution of coarse aggregates and fine aggregates in concrete mixtures in order to increase the value of compressive strength and bending strength in concrete, especially for rigid pavements. The method in this research applies experimental methods, the tests carried out in this study include material testing, compressive strength testing and concrete bending strength testing. Testing is carried out referring to the American Standard Testing and Materials (ASTM). Based on the experimental results; the highest compressive strength value of concrete obtained in the 3rd concrete variation with a concrete mixture of 100% Silica sand + Natural gravel + Sikament NN with a value of 41.14 MPa. For the optimum bending strength value obtained in a concrete mixture with the 4th variation, namely 100% Natural sand + Silica Gravel + Sikament NN with a value of 1.6 MPa. Based on the results in road planning, the 4th concrete variation was used as a variation that will be applied on the basis of its optimum bending strength value and a compressive strength value that exceeds the design compressive strength which is 32.36 MPa. The planning for rigid pavement on Jalan Simpang Anak Aia – Fly Over Minangkabau International Airport STA 22 + 800 to STA 22 + 800 by using the MDP2017 method, with the pavement thickness of 27.5 cm.
