In this research, we payed attention to elastic pavement on witch we tumbled sefety relatively in all walkway pavement, in order to decrease the denger of “Serious injury when tumbling on it”. We considered about “Range of hardness relatively safe even when tumbling on it”, “Range of hardness comfortable for walking of a normal person”, “Range of hardness comfortable for passing through with a wheelchair”, and we proofed that “Common range of proper hardness for safe and comfortable passage” was the range of 70 G to 90 G.
