Improving the Performance of Permeable Concrete Pavement by Replacing Sedimentary Travertine Aggregate

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...

Samples development and testing with three replicates for each sample was carried out at the Concrete Technology Laboratory of Semnan University.

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.

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.سعید فرزینmahsa doostmohamadihojat karamisayed farhad mousaviOmid RezayfarIranian Society of Structrual Engineering (ISSE)articlepermeable concretetravertineaggregateporositycompressive strengthBridge engineeringTG1-470Building constructionTH1-9745FAJournal of Structural and Construction Engineering, Vol 6, Iss شماره 3, Pp 5-16 (2019)
