Title

Improving the Performance of Permeable Concrete Pavement by ReplacingSedimentary Travertine Aggregate

Pages

  5-16

Abstract

 Increase of impervious surfaces in urban areas, has led to many problems, including flooding roads and streets during rainstorms which could create difficulties for pedestrians and cars. An effective way of reducing urban runoff and waterlogging is to use Permeable concrete pavement. In the present study, the effect of replacing different percentages of Travertine additive with the main Aggregates of Permeable concrete on physical and mechanical properties of this type of concrete has been studied. Samples development and testing with three replicates for each sample was carried out at the Concrete Technology Laboratory of Semnan University. Statistical analysis of the results was carried out using SAS 9. 4 software at 95% confidence level for all the samples. Results showed that due to the porous structure of Travertine, increasing the percentage of Travertine replacement with Aggregate increased the Porosity and permeability coefficient. The highest Porosity was observed for T-100 and T-75 specimens, which was 29. 13% and 28. 78%, respectively. Also, the highest permeability coefficient (1. 96 mm/s) was for T-75 and T-100 specimens. Other results indicated that replacement of Travertine with a percentage of Aggregates in porous concrete reduced the Compressive strength of the samples compared to the control sample. Maximum and minimum Compressive strengths were 17. 33 and 12. 22 MPa, respectively, for T-25 and T-100 specimens; While the compression strength of the control sample was 18. 45 MPa. Based on the results, due to Porosity, high permeability and suitable resistance of this Permeable concrete with Travertine, this type of concrete has high potential to be used in pavements, especially in areas with low traffic.
