“…In basic rest areas, the hardness of the sidewalk pavement blocks should be determined with consideration of the safety and comfort of users, especially the elderly. It is commonly accepted that repulsive force is higher in concrete and asphalt pavement materials (Nabeshima and Yamada, 2005;Takeuchi et al, 2008;Takeuchi et al, 2011;Higuchi et al, 2011;Choi and Lee, 2004;Choi et al, 2017).…”

“…There have been few implementation studies on sidewalks, square plazas, trails, and playgrounds paved with wood or wood products, such as wood plastic composites in Japan and South Korea (Nabeshima and Yamada, 2005;Takeuchi et al, 2008;Takeuchi et al, 2011;Higuchi et al, 2011;Choi and Lee, 2004;Choi et al, 2017;Ko and Ko, 2015). It is, however, surprising that wood block pavers were the main paving materials for the horse-powered carriages before the 20 th century and this relevant history is presented in Section 2.…”

“…It was found that a comfort zone lies in the measured range of impact acceleration of roughly 80±10 G. Takeuchi et al (2005) used this range to pursue structural engineering designs for pedestrian pavement with resilience performance based on the elastic modulus obtained in portable FWD testing and the impact acceleration from hardness testing of paved surfaces. The elastic modulus range corresponding to the impact acceleration within the hardness range that provides safety and comfort for pedestrians, including the elderly and wheelchair users, was recommended to be 25 to 80 MPa (Takeuchi et al, 2008) and 30 to120 MPa (Takeuchi et al, 2011).…”

A wood-plastic composite (WPC) paver block was manufactured using wood chips waste through an extrusion process, and it was intended to be used for paving in basic rest areas. The first stage in this study covered preliminary tests in terms of flexural strength and dimensional swelling to determine the optimal WPC compounding mix condition, by variation of the WPC ingredients. Next, three different paver blocks including the WPC block, a non-porous cement block, and a porous cement block were tested in terms of various material properties in the laboratory. Finally, two outdoor test sections of the proposed paver blocks were prepared to simulate a basic rest area. Test results indicated that the flexural strength of the WPC paver blocks was about 1.6 times greater than that of the tested cement paver blocks. The WPC block pavement was unaffected by water buoyance as well as volume expansion due to swelling. Results from the impact absorbance test and light falling weight deflectometer (LFWD) test clearly showed that the WPC block paving system marginally satisfied the comfortable and safe hardness range from the pedestrians' perspective, while the results demonstrated that it is structurally sound for application as a road paving block.
