3 KPIs for Testing of Materials and finished Works• AQTS (PEMS) reflects the compliance of sampling and testing in three (3) KPIs (shows as

speedometers)• The number expressed in each speedometer is the Percentage of Compliance of all the tests included

in each one of the 3 KPIs Unbound Loose Mix Test Results Compliance –Percentage of Passing Results i.e. 93.6% of the Unbound Loose Mix Test Results are in Compliance with the specs

As Constructed Test Results Compliance –Percentage of Passing Results i.e. 99% of the Test Results are in Compliance with the specs

Asphalt Loose Mix Test Results Compliance –Percentage of Passing Results i.e. 100% of the Asphalt Loose Mix Test Results are in Compliance with the specs

Example of KPI 1: Test Results of Unbound Materials & Pavement Layers

Example of KPI 1: Test Results of Unbound Materials & Pavement Layers

Examples of conducted Tests:• Gradation• Liquid Limit, Plastic Limit and

Plasticity Index • Acid Soluble Chloride/sulphate

content, Soundness• CBR• Clay Lumps and Friable Particles• Fractured Faces• Shell content• Elongation index• Flakiness Index• Flat and Elongated Particles• Material Passing No. 200• Los Angeles Abrasion• Organic Impurities• Sand Equivalent

Pavement Layer/Materials:

Fill Material Subgrade Subbase Roadbase Coarse and Fine Aggregates

Example of Trend Analysis for KPI 1:Testing of Unbound Materials & Pav. Layers

Trend Analysis For each KPI, the

performance of the project or of the Contractor can be assessed

Trend analysis is available for the last 2 years of each project at this phase

3 KPIs from QSD-ANAS Audits

• PEMS reflects the compliance to QCS assessed during Audits in three (3) KPIs (shows as speedometers)

• The number expressed in each speedometer is the Percentage of compliance of the Audits conducted by QSD-ANAS

Quality Management System Score Percentage of compliance of documental Audits related to the Quality Management System.

Production Facilities Score Percentage of compliance of on-site Audits related to the Production facilities (Asphalt plants, Wet Mixing Plants, Crushers, etc.).

Construction Practices Score Percentage of compliance of on-site Audits related to the in-place activities during laying the material.
