1前言自从连锁混凝土砖被引入日本,累计总铺设面积已达到1亿5千万m2。但是,铺在行车道路上的仅占10%左右,并且在行车道上使用率正在逐年降低。2010年,日本全国连锁混凝土路面砖的总铺设面积约为3,060,000m2,其中铺设在行车道上的面积仅占总应用量的7%。这个比例仅是德国占总应用量65%的1/10。在 1 Introduction Since the introduction of interlocking concrete bricks in Japan, the cumulative total installed floor area has reached 150 million m2. However, only about 10% are laid on the road, and the usage rate on the roadway is decreasing year by year. In 2010, Japan’s national chain concrete pavers had a total installed area of ​​about 3,060,000 m2, of which only about 7% of the total installed capacity was laid on the traffic lane. This ratio is only 1/10 of 65% of total applications in Germany. in
