Abstract

The paper discusses in brief existing practices with road marking materials. As an alternative the use of 100 mm diameter plastic studs which are manufactured locally at Madras, India is investigated. The economic spacing of road studs under the local traffic conditions for ascertaining the minimum number of studs required for every 1 metre length which would give a visual effect of a solid line of the same length is assessed. The guidelines provided by Hobbs and Richardson for the length of stroke and gap have been adopted which proved more economical as compared to the standards prescribed by Indian Roads Congress. It is recommended that the economic stroke length of 0.9 M and gap length of 7.5 M could be adopted. Three plastic studs may be embedded in each stroke with a spacing of 400 mm between centres of successive studs. (TRRL)
