1 Basics Initial conditions Budgetary deficits for construction, maintenance and operation for streets Dramatic deterioration of the conditions of streets and constructions High economic defeats caused by a reduction of the fixed asset, road traffic noise immission, inadequate road safety, congestions and longer ways extensive reduction of administration structures caused by budget reductions

1 Basics First steps PPP – acceleration law / 08.09.2005 Coalition agreement: Stimulating of private capital within traffic way construction Introduction of lorry toll since 1.1.2005 Realisation of 4 (5) A- models Realisation of F- models Utilization of functional construction agreements Maintenance model / Thuringia for rural streets

1 Basics Forms for realization in construction, maintenance and operation:

2 A-Models - Overview Pilotsections A-Model A 8 Eschenriede – Augsburg West A 4 Hörselberg - bypass A 5 Baden-Baden – Offenburg Süd A 4 Kerpen – Düren A 1 Buchholz – Bremer Kreuz

2 A-Models - Overview Thüringen A 4 – Hörselberg-bypass

2 A-Models Typical cross section Extension to additional lanes Existing 4-lane cross section mit oder ohne mit oder ohne Standstreifen Standstreifen 1,50 2,50 3,75 3,75 3,50 3,75 3,75 2,50 1,50 0,75 0,75 0,75 0,75 Hereafter cross section 35,50 14,50 RQ 35,5 R Q35,5 12,00 1,50 1,50 2,50 3,75 3,50 3,50 3,50 3,50 3,50 3,75 2,50 0,50 0,75 0,75 0,50

3 Maintenance model in Thruringia Nordhausen - Federal highways 1.848,5 km - State roads 5.174,4 km Mühlhausen - Local streets 2.434,4 km Erfurt Weimar Altenburg Eisenach Gotha Jena - 28 local road operation units Gera - 1997 – 2002 Change to GmbH Ilmenau Suhl Saalfeld Meiningen 100% state controlled company Eisfeld After 5 years physical privatisation TSI GmbH – 17 local operation units

3 Maintenance model in Thruringia Example Pilot project for ca. 20 km Maintenance model for state roads Construction – Maintenance – inside the Saale-Holzland-area Operation 30 years contract Guaranteed money for 30 years Functional announcement

3 Maintenance model in Thruringia aimed to demand - renewal, maintenance and operation of a selected communal road network Functional announcement for construction, maintenance and operation Projectfinancing (private own capital) and forfaitation as elements for financing recompense linked to a fullfillment a special road network condition Availability linked with a bonus-malus system obligation inside the state budget volume more than 100 Mio. € for 30 years gradually transfer within the rural road network road administration only responsable for origin administration tasks

3 Maintenance model in Thruringia - Possibility of financing - Task description (functional) - Life cycle view (advantages in productivity) - Distribution of risks - repayment guided through achievement (Bonus/Malus, availability) - Functioning market (competition) - Projectvolume (compensation costs for transaction)

3 Maintenance model in Thruringia Operation works guarantee for a continuing lightness and fluidity of traffic Objective Level of demand is to fulfill in all parts of work structural maintenance Plant service service and maintenance of equipment cleaning winter maintenace further works e.g. road control Responsibility in the full time of 30 years

4 Foundations of searching for a road network Existing structures (classes of streets, existing local operation units Representation of street conditions – stand and development Further optimization of life cycle (construction, maintenance – unit over 30 years) Definition of maintenance strategys Classification of operation works for PPP Adjusting with existing structures of local street authorities Possibilities of financing

4 Foundations of searching for a net Development of a maintenance strategy Objective Objective Determination of the required maintenance demand on basis of the estimated road 1 1 level for quality and expected condition development Determination for short-dated measures 2 2 Steps Determination transferable maintenance demands under consideration of financial 3 3 devices 4 4 Realization of a maintenance program attributed to the network with long maintenance time intervals and with a view to a great benefit by an improvement of the substance of roads Maintanance strategy Maintenance requirement Maintenance program PMS- supported - Estimation of the results of measures - Assessment of alternative measures - Optimization of alternative measures, depending from available money

4 Foundations of searching for a net Quality assessment of surface conditions, pavement Objective Objective conditions and other road network facilitieste Assessment of road surface conditions After registation and assessment • Condition sizes • Condition values • separated value for use and substance • Complete value Condition sizes are converted in condition values Weighting and assessment of separated values

4 Foundations of searching for a net Representation of road condition Registration and assessment of roadconditions (measured visual assessment registration) - general unevenness (mm 3 ) AUN - Spurrinne ntiefe (mm) SPT With a 2 m - - Fictional water deepness (mm) SPH measurement - Non-skid-texture GRI - Net cracks, Riss crack accumulations(% of area) NRI % of area - Flickstellen (% of area) FLI % of area Transfer in a condition value

4 Foundations of searching for a net Dertermination of total value of surface conditions inside ZEB - system

4 Foundations of searching for a net Net visualizing Road network Condition values for visualizing singel-/netcracks (NRI) Example Federal roads - highways Legend -1,00 - 1,49 (besser als Zielwert) -1,50 - 3,49 (Zielwert überschritten) - 3,50 - 4,49 (Warnwert überschritten) - 4,50 – 5,00 8über Schwellenwert)

4 Foundations of searching for a net Standard-functions for condition development - condition development as a basis for risk estimation within the period of a life cycle - Assessment for E1- und E2-measures Construction year or last renewal Example Year of condition registration

4 Foundations of searching for a net System of maintenance (örtliche-punktuelle oder kleinflächige Maßnahmen) Bauliche Unterhaltung (Instandhaltung) (z. B. Vergießen von Rissen, kleinflächige Flickarbeiten) I 1 - auf der Deckschicht Bauliche (z. B. Oberflächenbehandlung, Dünnschichtbelag) Instandsetzung Erhaltung I 2 - an der Deckschicht (z. B. Hoch-/Tiefeinbau der Deckschicht) (größerflächige Maßnahmen) E1 - an der Decke (z. B. Hoch- oder Tiefeinbau der Decke) Erneuerung E2 - an Tragschicht(en) / am Oberbau (z. B. Verstärkung, Tiefeinbau einschl. der Tragschicht(en)) E1- und E2-measures, basis for road network development - PPP Riskdecreasing und riskestimation
