HC Deb 14 February 1964 vol 689 c123W
Mr. Charles A. Howell

asked the Minister of Transport if he will request the Road Research Laboratory to make a special study, during wet weather, of the water-holding propensity of the road surface of the M.1 motorway; and if he will make their report available to Parliament.

Mr. Marples

The Road Research Laboratory are still continuing their investigations into the water-holding propensities of various types of road-surfacings under varying intensities of rainfall and at different crossfalls. The research will include studies of the main types of surfacings used on M.1 and other motorways. It would not be practicable to carry out this work on the motorway itself. It is too early yet for any definitive findings to be published.
