§ Mr. GROVESasked the Minister of Transport whether his Department has experimented with the various forms of wood-block road surfacing and with what result; and whether he is aware of the new systems of water-tight and non-slipping surfaces?
§ Mr. PYBUSThe various systems of wood-block paving are well known to highway engineers, and I can safely assure the hon. Member that it is not necessary for my Department to undertake experimental work concerning them.
