- Synopsis
- This paper reports the outline of the quality standard and test method of water-retentive concrete block pavement established by the Japan Interlocking Block Pavement Engineering Association (JIPEA) in July 2005. The authors confirmed the effectiveness of water-retentive concrete blocks in controlling the increase in road surface temperature in summer by field-testing fifteen types of standard-complying blocks constructed in an actual environment. Based on an analysis of the results, the authors also report the effects on road surface temperature of the color of the concrete block surface, the quality of each type of block, the existence of cushion and joint sands, and the system of supplying water to the pavement.
