Many factors cause road damage, including weather, weather on the road surface when it rains, scorching heat in the dry season, average daily traffic volume (LHR), and vehicles that have a number of loads or overloads (Overloading).

Concrete has many uses in civil engineering, especially in a building structure. To support the load of a structure, it is necessary to have concrete with a high compressive strength. In the design of high compressive strength concrete, additional materials can be used in the concrete mix in accordance with the function of use and the right level. The use of rice husk ash and granulated sugar is considered to increase the compressive strength of concrete if used at the right levels. This study aims to determine the effect of using Rice Husk Ash and granulated sugar in increasing the compressive strength at the age of 3 days, 14 days, and 28 days, it is necessary to make a study. This research uses rice husk ash and sugar added. This study used Rice Husk Ash as much as 10% and 0.2% granulated sugar by weight of cement and a 0.4 phase value.
