Abstract

Roads are one of the transportation infrastructure which is an important element in the
development of national and state life, and the function of society as well as in advancing general welfare
as intended in the Preamble to the 1946 Constitution of the Republic of Indonesia. (R.I. Law No. 38 of
2004 concerning Road). One of the common problems that occurs during road maintenance is the
appearance of cracks on the road surface. These cracks can be caused by several factors, including high
traffic loads, extreme temperature changes, and weather influences such as rain and heat. These cracks
not only reduce driving comfort but can also cause more serious road damage that requires quite large
repair costs. To avoid damage to the pavement surface due to the influence of excessive loads as well as
the influence of water and weather, to overcome these problems alternative synthetic materials can be
used in the form of materials that meet specifications to improve the quality of the road surface, namely
high quality asphalt mixtures. Coal is a fossil fuel, the reserves of which are quite abundant in Indonesia
and are estimated to reach 30 million tons. With good quality coal and large quantities and current
production levels, coal can be an energy source for Indonesia for hundreds of years. From burning coal,
around 5% of solid pollutants are produced in the form of ash (fly ash and bottom ash), of which around
10-20% is bottom ash and around 80-90% fly ash of the total ash produced. The large amount of residue
(fly ash) will cause problems, especially in the disposal process because it can pollute the surrounding
environment and requires relatively expensive disposal facilities (Wardani, 2008). Therefore, this residue
has begun to be processed as a civil engineering building material, for example as fly ash cement, a
mixture of bricks, as a backfill material, and can also be used as a pavement layer material.
