Durability Characteristics of Sustainable Pervious Pavement Materials
This study focused on the durability characteristics and moisture susceptibility of a porous plastic-based cementitious material (P-PBC) that is manufactured from plastic waste (PET), soil and aggregates. Use of this material will reduce storm water runoff and provide a pavement structure suitable for walkways, parking lots, recreational courts and other applications. It will also play a crucial role in current recycling programs by diverting large quantities of plastic from landfills and incinerators. P-PBC specimens were prepared in a two step procedure: (1) melting the PET flakes and mixing them with the soil at the melting temperature of plastic until a uniform mixture was attained and (2) thoroughly mixing the PET-soil mixture with the aggregates until uniformity was obtained. Specimens had a plastic to soil ratio (PSR), by weight of 0.75 and a plastic to aggregate ratio (PAR), by weight of 0.175. After compaction, prismatic specimens were cured for 24 hours and tested for freezethaw durability in accordance with the ASTM C666 test method. Results showed that the dynamic modulus of elasticity and modulus of rupture of the specimens decreased as the number of freeze-thaw cycles increased; in addition, moisture susceptibility tests were run according to the AASHTO T-283-89 test method. Results showed that the average tensile strength ratio of P-PBC specimens was greater than 70%, which indicated that P-PBC specimens were not susceptible to moisture.
