Sir Clive Bossomasked the Minister of Transport, having regard to the need to reduce the danger of wet road skidding on newly constructed motorways, if he will give details of the evidence in his possession on the relative advantages and disadvantages of concrete roads against asphalt roads; and what reports have been made by the Road Research Laboratory on all aspects of this matter.

The results of an assessment of these costs are contained in Road Research Laboratory Report LR.256.
