| Abstract | ||
| The infrastructures are one of the basic elements which reflect nation’s development; therefore infrastructures are the main concern for all of the Officials responsible for development and maintenance of infrastructures. Preceding from this fact the main goal of the researcher is to build a management system, base on site investigation for pavement plants in several projects, to study their productivity and trying to improve them. After the completion of data collection for all plants which were used for road pavements, and process these data, several factors were found which affect their productivity. Based on the above, many suggestions were made, that will rise the productivity of these plants such as systematic planning, determine the requirements for the tracks that is used, types and number of rollers and finishers, number of compacting, speed of finisher, and gang size. All these factors may insure a good execution for the work, and also the construction of height production asphalt patching plants, maintenance, monitoring, daily tracking, training courses for the staff, provision of spare parts. An equation is determined for the optimum number of tracks, and also another equation for daily productivity per ton for the finisher is determined. Idle time for the finisher is determined, from the collected data, and from the finisher speed which was estimated in the finisher manual, and the asphalt layer thickness and density, equals to (18%) in the branches and (22%) in the main roads. The researcher is also determined a computer program for calculating the finisher productivity depending on the surrounding environments. | ||
