Workshop on road maintenance planning

A workshop was arranges on maintenance planning. The general concept was introduced and it was explained that first longer-term strategic planning is performed to define the desired target level for road condition and budget. A realistic budget is then used for periodic maintenance planning, where medium-term, multi-year network level plan is created. This plan is updated on annual basis. The plan is based on road deterioration models, work effects models, road user cost models, maintenance standards and unit costs of maintenance works. [Read More]

Road inventory training

The roads belonging to roadclasses A, B and C have been surveyed using a 360-degree camera and a lidar. Orthophotos have been prepared on the road surface and immediate surroundings. Two specialised software have been installed on the Ministry’s server: one can be used to have a 360-degree streetview on the roads and the other one can be used to visualise the pavement. The idea is to collect necessary inventory and condition items from the photographs. [Read More]

Traffic variation

Information on traffic volumes is extremely important not only in decisions on capacity increase, but also in prioritisation of bridge and road maintenance works. Collection of traffic information on all the roads and of all the vehicles is not possible and therefore some of the values are estimated. Overall, the variations in traffic volumes can be divided into the following categories: Variations by hours (these may also vary by weekdays) Variations by weekdays Variations by months (weeks) Trends Random variations The initial counting results reveal that almost 10 % of the daily traffic takes place between 07:00 and 08:00 and that Friday has most traffic.

Routine maintenance

Pothole unit was seen in action. Routine maintenance is extremely important and adequate budget should be allocated in annual basis. In the future there will be modernisation in equipment, work methods and prioritisation. A general rule is that routine maintenance is in such a level that potholes do not exist for long. Also, the root of the problem of poor road condition should be addressed. Often the problem is poor drainage, which causes the water to damage the base and decrease bearing capacity causing alligator cracking on the roads. [Read More]

Workshop in institutional development

A workshop was held on institutional development. A draft roadmap was introduced with the following development topics: Road related data and its collection Road Asset Management system Road policy and sustainable funding Long and mid-term planning processes as a management system Budget structure and key performance indicators Corporate Plan Maintenance standards Supervision and Quality control Selection of contractors and quality of contractors’ work Co-operation with WASCO Group works focused on some of the development topics.

Bridge inspections on the way

Bridges are being inspected

The first 12 bridges have been inspected. It is not yet known how many bridges there are in total, but the current estimate is 180. The bridge inspection was slow in the beginning as the future inspectors were trained at the same time. During the first week of inspections the inspection time was reduced from three hours to half an hour.

Traffic counters installed

Installation of portable traffic counters

Ten portable traffic counters have now been installed on the traffic counting locations. The counters will remain for a week on the spot and then they are moved to new locations. Later, the portable counters are complemented with permanent counters and manual traffic counting.

Traffic counter training

Installation of portable traffic counter

Training was given by Metrocount on installation and operation of portable traffic counters. The Ministry has 12 units that will be used for one-week counts on approximately 200 locations. Weekly traffic count data is complemented with manual counts as well as permanent counting in two locations.
