| Abstract | ||
| In this paper, 18 single-sized pervious concrete mixtures were tested. The mixtures were prepared by altering: the amount and type of binder, type of aggregate, and the method of compaction. Concrete was compacted in layers in one of five different consolidation techniques: with standard tamping rod, wooden lath, concrete cylinder, or vibration of 12 and 40 s. Tests carried out on the specimens were: slump, density, porosity, coefficients of permeability, compressive strength and splitting strength. The relationships between porosity-density and porosity-strength were established. Two mixtures were selected for the preparation of test slabs on different subgrades and their permeability was tested according to ASTM C 1701-09 Standard. By comparing laboratory and field tests of permeability, it was concluded that the subgrade affects the test results. Measurements on the test slabs were repeated after 1 and 2 years of installation. | ||
