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
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.
