BITUMINOUS PAVEMENT MAINTENANCE EQUIPMENT

Well planned road maintenance economizes treasury finances. Administrations carry out works on their own or contract them. For their execution stationary or mobile asphalt plants are used and in cases where a crane is not available plants that can be erected without crane are valuable for their fast self-erection. For smaller works, compact trailer-mounted plants operated by diesel engine are indicated and if dustfree aggregates are available drum mixer plants are suitable. The drum mixer is more convenient also for recycling, with the addition of a second input for the recovered material. Accurate grading analyses must be carried out when using scarified pavements in recycling. Equipment for special purposes can be fitted to any type of asphalt plant. Small or medium size paver finishers are the most used for maintenance, also with the hydraulically extendable screed. Bitumen can be stored either in "hot points", i.e. deposits of hot oil heated storage tanks, or in "drums", when a regular supply is not available. To empty bitumen from drums into the storage tanks, melting furnaces are used. From the "hot points" liquid bitumen is transported by tanks fitted with heating and emptying systems. A wide range of equipment is available for spraying binders in surface treatments: tanks with spraybars and spraylances; tanks with manual spray fitted onto the bed of a truck; self-propelled sprayers that can be refilled with bitumen in drums; trailed heaters; two-tank compressed air bituminous emulsion sprayers. To spread chippings and gravel both mechanically and manually a type of chipping spreader fitted in the place of the tailboard of a truck is highly practical. Equipment fitted to trucks and three-wheeled vans for transport of personnel, aggregates and bitumen is a valid solution for urban maintenance. The most used compaction means are small and medium size vibratory, static and pneumatic tyre rollers. For sidewalks simple and low cost equipment are indicated and for night maintenance self-sufficient flood light units with hydraulic light shafts are particularly interesting. (TRRL)
