§ 75. Mr. Russellasked the Minister of Transport if he will publish in the OFFICIAL REPORT a list of the different types of road surfaces in use in the United Kingdom, together with figures showing to what extent they are skid-proof.
§ Mr. BarnesThe main types of road surface are asphalt, bituminous macadam, concrete, stone setts, tarmacadam, water-bound macadam and wood blocks. There are variations of each type. In addition, there are various kinds of surface dressing and thin carpets. Resistance to skidding depends upon a number of factors, and for information as to the tests which have been carried out I cannot do better than refer the hon. Member to the published reports of the Road Research Laboratory.
