The distribution of road aggregates can be a costly item in thinly populated areas of developed countries such as Australia and New Zealand. This paper gives details of a project in New Zealand whereby fully mobile plants operate which move from one production point to the next, staying long enough to generate sufficiently large stockpiles until the next visit. The project relates to operations by Waitomo District Council, responsible for a land area of 1298 sq miles and a population of 12500. The area is serviced by 1240 km of county roads and 150 km of state highways. Aggregate materials in the county comprise greywacke and limestone. A detailed description is given of the portable crushing plant which was designed in 1973 to achieve economies at the four existing quarries and give the capability of exploiting other rock sources in the district with the attendant benefit of reducing haulage distances. As well as describing the components making up the plant, details are given of conveyors, power requirements and accessories and a brief mention is made of some of the problems associated with transporting such plant from point to point. A list of suggestions for improving the system is included. (TRRL)
