“…Volcanic ash filler as a mixed filler has not been widely used, in fact it may not have been done. [1] Several types of hot mix asphalt commonly used in Indonesia include: AC (Asphaltic Concrete), HRS (Hot Rolled Sheet) and HRSS (Hot Rolled Sand Sheet). [2] Volcanic ash is a type of tephra (air volcanic extrusion), which is usually destructive at first but can be useful over time.…”

Asphalt mixture is a combination of a mixture of aggregate and asphalt. Sinabung eruption volcanic ash produced many negative impact on health and the environment. So that needs to be done in order to study the volcanic ash can be used in road pavement, especially on Asphalt Concrete pavement, the purpose of this study to determine the effect comparison of volcanic ash filler sinabung on Asphalt Concrete - Binder Course. This research was laboratory experimental in nature with asphalt level variation of 5%, 5.5%, 6%, 6.5%, 7% and volcanic filler level of 1, 2 and 3% in each asphalt level variation. There were 5 samples used the examination was done using marshall test instrument. The test used to determine the graph of asphalt content with value stability, flow, bulk density, VIM, VMA, VFB. The results of the over all addition of volcanic ash in the petroleum asphalt. Asphalt Concrete Binder Course Marshall stability values indicate that the better that showed that a mixture of aggregate is very good. If the flow value is lower, the VIM value is getting lower, then the VMA value and VFB value have a value that is more than the minimum value.

Fly ash is a material suitable for making concrete because of its silica, alumina, and calcium contents, which can improve the compressive strength of concrete. In this study, the researcher tried to renew a mixture that is resistant to corrosion using fly ash and calculating the powder in an oven at 200°C for 60 min to change the nature of the shell powder to become reactive in a concrete mixture. Using experimental methods and supported by previous studies. In this experiment, normal concrete (Fc' = 30 MPa. In this study using 6 formulations, with Fly ash 10%, 10%, 15%, 10%, 5%, and 13% of cement and clamshell power 10%, 20%, 20%, 20%, 20%, and 17%, respectively) from sand. The influence of seawater on salty materials, such as shells, and pozzolanic materials, such as fly ash, during drying affects the compressive strength of concrete. The addition of 20% shellfish powder as a substitute for river sand and a combination of 15% fly ash as a substitute for cement (code. C3-SC) greatly affected the performance of concrete for application in marine areas, with the result that the compressive strength of this composition did not decrease. With a curing experiment using seawater, the compressive strength results at the age of 7 days were 23.93 MPa, at the age of 14 days were 33.55 MPa, and at the age of 28 days were 34.02 MPa. These results indicate that the compressive strength of concrete with this mixture does not decrease. From the research results, it can be concluded that calcined shellfish and fly ash powder materials can be applied to concrete in seawater areas.
