�Future Threats

Research Problem

�Traditional Maintenance System

�Increase rate of deterioration.

�Overloading of vehicles.

�Poor maintenance.

�Improper design and execution.

Current Threats

�Improper design and execution.

�Israeli occupation (direct and indirect effects)

�Limited resources

�Insufficient information for decision-making.

�Inefficient traditional management system.

�Population Growth

�Gaza Seaport Construction

Future Threats

� A lack of documentation.

� No use of database programs.

� Is not flexible enough to reflect changing conditions.

Traditional Maintenance System

� Is poor to assist in making decisions.

A strong Need For PMMS that contains:

�Database

�GIS Capabilities

Aim and Objectives

Developing a PMMS in which it provides:

�A systematic process.

�Tools to facilitate decision-making Process

Research Aim

�Constructing a suitable database for Gaza citypavements.

�Selecting an evaluation system for thesepavements.

Research Objectives

pavements.

�Integrating GeoMedia with Micro PAVER.

�Developing a Graphical User Interface (GUI).

Literature Review

Rapid, Comfort and Safe Movements of Road Users.

Pavement Distresses

�Cracking.

Pavement Mission

�Cracking.

�Distortion.

�Disintegration.

�Loss of Skid Resistance.

�Longitudinal and transverse cracking.

�Alligator Cracking.

�Block Cracking.

Cracking involves

�Slippage Cracking.

�Reflection Cracking.

�Rutting.

�Corrugation and Shoving.

�Depression.

Distortion involves:

�Swelling.

Disintegration involves:

�Raveling.

�Potholes.

Loss of Skid Resistance involves:

�Bleeding.

�Polished Aggregate.

�Fuel Spillage.

Deterioration Curve

Structural Failure.

�Functional Failure.

Pavement Evaluation

PCI Evaluation

Reduces the rate of deterioration and prolonglife of roads.

�Reduces vehicle operating cost by providingbetter riding quality.

Maintenance Aim:

�Keeps roads more open continually for traffic.

�Adds to the safety, comfort and disfatigue toroad users.

A scientific tool for managing the pavements soas to make:

�The best possible use of resources available.

PMMS Definition

�Maximizing the benefit for society.

Thus, PMMS can be used in directing andcontrolling maintenance resources foroptimum benefits.

� Provide an inventory of pavements.

� Provide a comprehensive database.

� Show the current condition of the pavement network.

� Serve as a base for comparing alternate maintenancestrategies.

PMMS Benefits

strategies.

� Help to predict the condition of the network overtime.

� Estimating budget required to bring the roadway todesired condition levels.

� List ways to prioritize expenditures.

� Be a base for communication among groups insideand outside an agency.

�Replace engineering evaluation.

�Make all decisions at the press of a button.

�Provide agencies with all answers.

Conclusions and Recommendations Recommendations

� Adequate database for Gaza pavement network has beencreated.

� Pavement Condition Index (PCI) has been selected as atool for Gaza pavement network condition assessment.

� Micro PAVER has been used to evaluate Gaza pavementnetwork.

GeoMedia Professional has been used to handle all

Conclusions

� GeoMedia Professional has been used to handle allgeographical and descriptive data related to Gazapavements.

� A system has been presented to facilitate the decisionmaking process for managing Gaza city pavements.

� A simple Graphical Interface has been developed inwhich it contains user-friendly menus.

� This system has been tested through selecting a casestudy zone (about 20 km of road long).

� A centralized PMMS should be initiated to involve allcities in Gaza Strip.

� Future developments should be made to ensure fullintegration between Micro PAVER and GeoMedia.

Future developments including other elements of a

Recommendations

� Future developments including other elements of ahighway maintenance management system should beconsidered.

� There is a great need of long-term commitment ofofficials, pavement managers, public and road userstowards the conservation and protection of Gazapavement assets.
