Abstract

Floods in Samarinda occur every year. It^s because the infiltration area is getting narrower, the drainage conditions are full of garbage, high rainfall, and the behavior of people who litter. So, it needs improvement technology to reduce these problems. One way is to make porous paving that can absorb water from the soil surface into the ground of soil, use local materials. The purpose of this study was to investigate the effect of local Kalimantan material on the strength and porosity of porous paving. This research begins with a literature review, then material procurement, and material testing. After that, make a mix design paving. Make of specimens with a variation of fly ash 10% and sand 0%, 2.5%, 5%, and 7.5%. Then the paving compression test at the age of 7, 14, 21, and 28 days. From the research results, it indicated that the maximum compressive strength in the addition of 7.5% sand with the compressive strength of porous paving is 11.6 MPa, while for the highest porosity of paving with the addition of 0% sand.
