§ Sir G. PENNYasked the Minister of Transport whether any inquiries have been undertaken to ascertain the relative prices of rubber road-surface material as 1980W against other materials now used; what would be the difference in cost of materials and laying per 100 square feet; and whether he will suggest to local authorities that they should ascertain whether, in view of the additional durability of rubber and anti-vibration qualities, it is a practical proposition to use it where they have heavy traffic?
§ Mr. HERBERT MORRISONI am informed that the cost of rubber paving blocks very substantially exceeds that of the more expensive types of other suitable paving materials the wearing qualities of which are well known. I explained to the hon. Gentleman on the 17th of June that I do not see my way to urge local authorities to use this particular material.
