Concrete is a material that has high strength to withstand loads. One of the uses of concrete in the construction field is as a road pavement which is often called rigid pavement. Rigid pavement is brittle so it cannot withstand large tensile loads, so it requires rubber crumb as an added material. Waste rubber crumb from used tires has good benefits for concrete to increase the strength of concrete in resisting tensile and flexural loads. This study aims to assess the physical and mechanical properties of concrete at 7, 28 and 56 days using a combination of rubber crumb (CR) with cement, fly ash (FA), and silica fume (SF) as a binder. Four concrete mix variations in this study were 5% rubber crumb, 5% rubber crumb + 5% fly ash, 5% rubber crumb + 5% fly ash + 10% silica fume. The control concrete was 100% PCC with a planned compressive strength of 40 MPa. The results of the compressive strength test showed the highest compressive strength value in PCC CR FA SF concrete with a 56-day old compressive strength value of 43.15 MPa. The highest concrete tensile strength value is obtained by PCC-CR-FA concrete with a value of 3.53 MPa at the age of 56 days. The results of porosity and water absorbtion testing of concrete show the highest value in PCC CR concrete with a value of 12.05% and 5.33% aged 7 days and the lowest sorptivity value is shown in PCC CR FA SF concrete with a value of 0.12%. The highest concrete shrinkage test results are shown in PCC CR concrete with a shrinkage value of 0.0633%. Based on these test results, concrete with the addition of 5% rubber crumb + 5% fly ash + 10% silica fume shows good potential as an innovation in the application of concrete as a rigid pavement material.
