Why is it Happening – Pavement Design ?

Presenter
Presentation Notes
It is important to understand the major difference between Pavement design in South Africa and the Northern Hemisphere. Due to extensive use of natural materials and thins water proofing surfaces, our pavements are very moisture susceptible, and thus needs to be closely monitored and managed.

Presentation Notes
This slides indicates the primary reason for why SANRAL is in the process of incorporating roads that is part of the strategic national road network currently under Provincial government control, under its jurisdiction. Due to no or very little preventative maintenance being performed by provincial governments as a result of severe budget and capacity constraints, the strategic road network has entered a phase of accelerated deterioration. As seen the cost impact of delaying maintenance on a road maintenance delayed by 3 years will result in an additional cost of six (6) times the original amount. And should commencement of maintenance be delayed a further 2 years the funding requirement will increase dramatically – eighteen (18) times the original amount.

Presentation Notes
As seen from this slide the impact of a deteriorating road network is primarily on the road user, with road user costs increasing more than 100 % from good to very poor road. Although this cost increase is not directly felt by government, the economy is severely impacted.

Birth/Rebirth of a Pothole ?

New Road - Deterioration over time due to Traffic Loading &

Environment

NO Preventative Maintenance - Crack Sealing - Cleaning Drainage Structures - Cutting of Grass

Presenter
Presentation Notes
Asset Management “101” We typically structurally design roads for the traffic loading expected over 20 to 30 year period, so a road is not necessarily designed for 20 calendar years, but the traffic expected in 20 calendar years. Let say we have two roads today, call them A & B, as seen they are both in the exact same condition, and have the exact same traffic, but only have funding for one of them, what do you do ? Well if I told you that I had historic condition data, and from this data the following trends can be observed, then one can with more certainness go for option B, why, because the consequences of maintenance delay is the highest, or in other words it deteriorates the fastest. If we now add the further ability to predict future anticipated performance, the decision is even easier.

Presentation Notes
This slide shows typical field data collected for a complete truck in the field. Red indicates contact stresses in excess of 1MPa. Please note that none of the contact areas are a circular uniform distributally load as commonly assumed in pavement design models. Also note the distribution in load carried by wheels on the same axle. This is real life. In South Africa we are currently using the above information to move away completely from the E80 concept within the next 3 years.

• Policy/Procedures – Principles/Rules to Guide Decisions and achieve rational outcomes – what, where, when, how.

• Funding – Financial resources for operation and results implementation. • People - People make decisions, the rest are just to support the process. • Hardware – Road Survey Equipment + IT Infrastructure. • Software – Computer based data Analysis and Storage Tools. • Data – Knowing what you have, its condition and performance Trend.

• For asset management to be successful all the “pieces of the puzzle” need to be in place in a “balanced equilibrium”

• It does not help you have the most advance survey vehicle but no means to effectively store and analyse the data, or

• Have the most sophisticate software, but the quality of your data is suspect !

Presentation Notes
To ensure accurate decision making, accurate data is required. The data collected on SA National Roads include, visual assessment, I.e. cracking, potholes, patching, ravelling etc, roughness in IRI, HRI, rut depth, texture depth in MPD, surface friction using SCRIM and structural strength using FWD. The calibration/validation procedures and detail and frequency of data collection is all contained within our paper. Two other important data items collected is also traffic data, including WIM, and bridge condition data. All data is collected using GPS, we use Omnistar network enabling realtime differential data accuracy of less than 2m at speeds of 100 km/h.

Presentation Notes
Using dynamic segmentation the network data is broken up into uniform sections, which is then analysed using our PMS Decision Support Software. The process consists of modeling the Road deterioration, followed by the effects of maintenance, then calculating the effects on user costs for the various treatments. Finally the economic analysis is performed followed by budget optimisation to produced the recommended works programme.

Presentation Notes
This ability to manage data is becoming more important the further we move in the pyramid from the data creator to the data viewer. It is for that reason when supporting the data viewer the IT infrastructure is of significant importance. In most organisations, a relatively small number of people actually creates data. But for every data creator, there are perhaps ten data users. They need easy access to current, correct data. And there’s perhaps another ten-fold increase in the number of people inside and outside the organisation who simply need to view the data (not manipulate the data). In order to make the reuse of technical data it is important that the information flow all the way up to the viewer. As a user can be a viewer, as well as a doer the next moment, we believe that it is of great importance that all of this can happen through a common user interface in a transparent way. This ability to manage data is becoming extremely important.

Presentation Notes
The slide indicates how the PMS information is distributed through the Agency, as seen the PMS are managed from Head Office, but all information (raw data as well as modeled data from PMS) is available to the various user groups via internet through a web enabled front end. The PMS analysis/modeling function can however only be performed in head office.
