Abstract
Cracks in a rigid pavement are the main cause of water entry into the structure. Method of repair cracks in the rigid pavement can be done in various ways, one is with the addition of Bacillus Subtillis Bacteria. Bacillus Subtillis is a bacteria that lives on the ground that has been separated in the laboratory. The purpose of this study is to find out how much influence in the addition of bacteria in a particular composition to a rigid pavement to repair cracks and analyze the most effective methods used to accelerate the process of repair cracks in a rigid pavement. The bacterial composition used was 104 Cells/mL of water, 105 Cells/ml of water and 106 Cells/ml of water, with the addition of medium peptone, NaCl and yeast extract mixed on the mortar test sample. The results showed a variety of variations, but the majority of the composition of 105 Cells/ml of water was the most effective composition improved, the crack improvement reached 93.33% on crack with dimension of 0.5 mm width and 3 cm depth at 60-day mortar age.
