§ Mr. Pawseyasked the Secretary of State for Transport what would be the additional cost if motorway repairs took place round the clock instead of the present system of working normal hours.
§ Mrs. ChalkerIt is not always practicable to work round the clock. Some repairs can be carried out only during the day, some only during the night. As a rough guide, costs for evening or night working can be twice as high as costs for normal day working.
§ Mr. Pawseyasked the Secretary of State for Transport what consideration has been given to the use of a quick setting compound, details of which have been supplied to him, to speed motorway repairs.
§ Mrs. ChalkerTwo quick setting compounds for patching roads that have been brought to my right hon. Friend's attention this year are now under trial. Conclusions cannot be drawn until sufficient time has elapsed to determine their durability.
