Due to the impervious features of conventional pavements and increasing road coverage areas, the heat island effect is becoming more severe, and many environmental problems have appeared [1]. Since, conventional interlocks have a disadvantage of being non-pervious and hindering the chances of water to seep in to the ground we are introducing a pavement block, whose central core portion can withstand the load applied with an M30 concrete mix (IS 15658) and 45% of natural coarse aggregate in this concrete grade is substituted by recycled concrete coarse aggregate (RCCA).The perviousness is achieved by attaching a 3D printed PETG (Polyethylene terephthalate glycol) frame structure with lofted circular holes for water to trickle down. The pavement blocks are subjected to visual inspection, dimension tolerance, compressive strength, water absorption and flexural strength test (three-point test) according to IS 15658. The tests were done on factory made pavement block, pavement block without frame and with frame, for all these tests to get accuracy. The test results showed that pavement block with frame has remarkable strength and the aim of perviousness can be achieved easily. It is identified that the interlock block with 3D printed PETG frame attached for perviousness have more compressive strength compared to interlock block without frame and factory-made block. It is also understood that the block without frame has the least strength compared to other two pavement blocks. The strength of pavement block with frame has a significant increase in strength due to 3D PETG frame.
