Abstract
The invention discloses a road cushion precast concrete and its laying construction method. The road cushion precast concrete is plate-shaped or has a ribbed-plate shape. The road cushion precast concrete is provided with connected pore channels, inside which a draining material such as sandstone or a drain board is arranged. In comparison with the prior art, the road cushion precast concrete prefabricated in advance is used as a padding material and is directly laid on the road bottom layer sand-gravel cushion or concrete cushion by a machine. The road cushion precast concrete can be produced in batch. The road cushion precast concrete is laid, and meanwhile, the foundation can be compacted with a higher intensity, processing effect is raised, and efficiency of construction is greatly improved. The connected pore channels on the road cushion precast concrete can help drain off and store water and can effectively prevent urban waterlogging.
