COWI & Dynatest - Global Alliance

A new strategic alliance between COWI and Dynatest will make a significant impact on related markets within the road, airport and seaport sectors.

COWI and Dynatest have formed an alliance with the aim of enhancing their joint consulting services to better serve customers within the fields of roads, airports and seaports.

Highly specialised
COWI has vast experience globally within the area of transport infrastructures, while Dynatest is highly specialised in global technology within pavement engineering.

The new COWI-Dynatest alliance intends to market its joint services globally, offering pavement and bridge management and engineering, including design, maintenance and rehabilitations.

WayLink Systems Corporation

Dynatest International A/S and WayLink Systems Corporation are pleased to announce, that as of 12th October, 2005, both parties have entered into a formal cooperative agreement for business alliance, through which Dynatest will exclusively internationally market specific WayLink video imaging and automated distress analysis technology in an integrated platform.

It is the intent of both parties that this alliance will further advance both the worldwide availability/support and quality of combined automated pavement engineering/pavement management non-destructive testing systems.

The new FAA approved Runway Friction Tester

Dynatest International A/S is pleased to announce the introduction of it’s latest FAA Approved Runway Friction Tester (RFT), the 6875.

This new RFT maintains the rugged characteristics of the 6810 and 6850 model RFTs and moves to a more user friendly platform.
The 6875 fully meets the FAA AC 5320-12C.

Our customers requested more wet testing capacity, optional four wheel drive, and more vehicle brand selection.

New PCN Module for Elmod5

PCN is a optional module to Elmod^® that uses the data files from Dynatest FWD/HWD equipment to calculate ACN/PCN values based on the methods used by ICAO.
The programme includes a database of over one hundred and twenty-five aircraft with ICAO ACN values.

PCN is the upgrade of the previous WinPCN program which is no longer available as a stand-alone program.

Per Ullidtz: "Modelling flexible pavement response and performance"

This textbook is primarily concerned with models for predicting the future condition of flexible pavements, as a function of traffic loading, climate, materials, etc., using analytical-empirical methods.

Own a signed copy of what many regard as the most comprehensive discussion on analytical models on pavement deterioration.

Dynatest and Mandli announces Partnership in Strategic Alliance.

The alliance serves to create an environment that will encourage cooperative dialogue on business and technical matters, and will allow the exploration of possibilities for the bundling, complementation, and/or integration of proprietary technologies.
In forming this alliance, Mandli and Dynatest signal their intent to be of better and more comprehensive service to the pavement engineering community.

- New Software Releases - From Dynatest

ELMOD^® 5.0 forms the core module of the Dynatest analysis suite, and at present we have two modules that can be attached to ELMOD^®: FEM/LET/MET module and LCCA module.

Survey is a package designed for assisting and utilising visual observation data.
The user-friendly program allows the users to modify the program for many types of surveys from visual surveys to traffic counts.

The Dynatest Pavement Management System and KORDAB Geosecma join forces

The pavement consulting engineering and manufacturing company Dynatest International A/S and the Swedish software developing company KORDAB, have entered into a formal alliance under which the companies wish to jointly explore the marketing and sales opportunities of their respective software programs and to co-operate in respect of the integration and possible further joint development of these software programs.
Initially their software modules relating to pavement and facility management will be seamlessly combined to provide an augmented system, but the aim is to launch a fully integrated product by year 2000.

This signals an important step for both companies initially in respect of their respective and existing users in Scandinavia, Poland, Baltic states, USA, UK and South Africa, but the bundled modules will similarly be marketed through Dynatest subsidiaries and joint venture companies around the world.

KORDAB’s software system GEOSECMA comprises 67 modules, with a core customer base of 160 Swedish municipalities.
The modules in the GEOSECMA software system interconnects through the core functions, however, output data from one module may act as input data to another module directly.
GEOSECMA spans from management and administration of water and sewage pipe networks, road and rail traffic systems to systems managing public parks and trees.

The Dynatest PMS is an internationally tested and proven system based on the Dynatest analytical/empirical pavement analysis methodology.
It has been in operation since 1981, being used on the road systems of municipalities, towns, counties, motorway authorities and on airports in Europe, the United States and Africa.
It makes use of performance models based on fundamental engineering principles. Reliable prediction of future pavement condition is based on actual, measured physical properties of pavements. Condition data consists of structural data gathered with the Falling Weight Deflectometer and functional data in terms of roughness and distress information.

The alliance will generate a more comprehensive and complete management system and is expected to profile both companies much stronger in the area of facility management vis-a-vis municipalities and counties.

California Department of Transportation - Accelerated Testing Program

California APT Update

The CAL/APT program has been in operation since July 1994.

This is a joint effort between the California Department of Transportation (Caltrans), the University of California at Berkeley (UCB), Dynatest Consulting, Inc. (DCI) and the Council for Scientific and Industrial Research (CSIR) from South Africa.

During the past seven years, accelerated testing has been completed on asphalt concrete and asphalt rubber pavements, primarily at UCB, on “fast-setting” hydraulic cement concrete pavements (FSHCCP) on State Route 14 near Palmdale, California, located approximately 70 miles northeast from downtown Los Angeles and on traditional portland cement concrete (PCC) pavements on State Highway 101 near Ukiah, California, approximately 150 miles north of downtown San Francisco.

The most recent testing took place at the Ukiah test site.
The testing involved retrofitting the existing pavement with dowel bars, the industry term used for this procedure is “dowel bar retrofit” or (DBR). DBR involves removing concrete material at the concrete slab joint, generally in the wheel paths, by sawing.
Then a dowel bar is placed in the slot created and permanently sealed in the pavement.
DBR is performed with the intent to extend the life of the pavement by increasing the joint load transfer.
It should be pointed out that both the Palmdale and Ukiah test sites were located adjacent to in-service pavements.
In fact, the HVS has recently moved back to the Palmdale test site where further investigation of the dowel bar retrofit (DBR) process is underway.

Both of the Caltrans HVS Mk III machines have recently been upgraded.
State-of-the-art electronics and new hydraulic components have been integrated into the existing mechanical framework, in order to improve the efficiency of the machines.
The upgrades have effectively resulted in HVS Mk IV capabilities on the Caltrans machines, except for tire pressure and temperature monitoring.
To date, the HVS in the field has applied more than 6 million actual repetitions.
The CAL/APT program is currently one of the most productive accelerated testing programs in the world and is planned to continue evaluation of pavement performance in California.
