| dc.description.abstract | Infrastructure plays a key role in the success of development, yet many
roads in Indonesia suffer from damage before reaching their planned
lifespan. This is often caused by the combination of alternating hot and
rainy weather, as well as increased traffic volume due to the rising number
of motor vehicles, all of which accelerate pavement deterioration. To
address these challenges, it is essential to develop road pavements that are
more resilient.This study investigates the feasibility of using Glagah Beach
sand as a substitute for fine aggregate in Hot Rolled Sheet (HRS) mixtures
and examines its impact on characteristics Marshall, IRS, ITS, TSR, and
Cantabro. The research is conducted in four stages: 1) physical testing of
aggregate and asphalt materials; 2) determining the optimum asphalt
content in the HRS mixture with varying Glagah Beach sand substitutions
0%, 25%, 50%, 75%, 100%; 3) conducting Marshall, IRS, ITS, TSR, and
CL; and 4) analysis and conclusion based on the results.The findings reveal
that Glagah Beach sand has a higher specific gravity than Clereng Sand,
meaning that for the same weight, the aggregate content differs. This results
in increased volumetric values with higher proportions of Glagah Beach
sand. Test results show that this sand, as a fine aggregate substitute in the
HRS mix, meets the required standards and can replace Clereng Sand. The
addition of Glagah Beach sand, in various proportions, has been proven
feasible based on the Marshall, IRS, ITS, TSR, and Cantabro tests, meeting
