PAVEMENT EVALUATION IN ARGENTINA

The 1970s: Acquisition of knowledge, equipments and

beginning of implementation

� Acquisition of 3 BPR Roughmeters, 2 Mu Meters and

5 deflectographs Lacroix

� Incorporation of the subject “Pavement Evaluation”

in the Post-Graduate School at the University

of Buenos Aires (UBA)

� Applications of the Road Needs Study

BPR Roughmeters from the

Argentinian National Road Agency (DNV)

Mu Meter: measures the transverse friction coefficient

DNV: Mu Meter for Friction Measurements

Long Chassis Model LPC-03

First experiencies in the use of the Deflectographe Lacroix in Argentina

DNV: Deflectographe Lacroix

The 1980s: Implementation and practical applications.

� Pavement Evaluation Methodology is established at

network level

� The whole National Network is evaluated anually during

the period 1980-1987

� The state parameters (roughness, rutting, cracking and

ravelling) are incorporated to maintenance contracts –

Toll Concessions

2 km (1983 - 1989) 1 km (1990 - 2003)

Sample section

� at Project Level: maintenance, overlay designs,

rehabilitations, etc.

� for performance prediction and service life estimation

� for HDM III and IV implementation

� to penalise maintenance contracts - Toll concessions


The 1990s: Masive, intensive and indiscriminate

applications of the Pavement Evaluation Methodology(DNV, DPVs, OCCOVI, toll entities, etc)

MANUAL-VISUAL METHODOLOGY

Sample section

The 2000s:

� In the specifications of the 2003/2008 concessions contracts,

it is mentioned for the first time and as an alternative to the use

of high performance equipments, and it is reduced to a sample

every 200 m, i.e. 5 per Km; in some special cases as in the

Access Network to Buenos Aires it is performed every 100

meters.

� DNV purchased high performance equipment for road

evaluation: MRM, SCRIM, FWD, ECODYN, radar

The 2010s: New Concessions Contracts for the Principal

National Network

� The use of high performance equipment is given priority:

“…the equipments to be used for measurements shall be

preferably high performance equipments, namely those which

perform a great number of on- the-spot tests and causing the

minimum traffic interference

The sampling intervals shall be every 200 m, 5 per Km”

• We have designed, assembled and tuned up a multifunction device

for Automated Pavement Evaluation and Road Inventory in

Argentina.

• Our aim was to produce a substantial improvement in terms of

objectivity, accuracy, performance and safety in the production and

administration of information for pavement management in order to

conform to the new requirements established in maintenance

contracts.

• The ASTRA system has characteristics of a multifunction device, but

at the same time it is capable of evolution, flexible and modular.

• ASTRA has already been used with satisfactory results in Argentina

and other Latin-American countries, and is therefore available for use

in the region.
