318,720 licensed motor vehicles

The National Statistics office of Malta issued a News Release on the 2nd August 2013, confirming that as at end June 2013:

  • 318,720 licensed motor vehicles are on the island. This is an increase of almost 1% from the previous quarter. The trend is that this increases yearly.
  • 416,055 inhabitants live in Malta, according to the last census of 2011 and this number includes children.
  • 76% of the population has a motor vehicle. This means that there are 3 vehicles for every 4 people.

If we had to line up all the vehicles one after the other we would need 1,912km of parking space (assuming that each vehicle can fit in a standard 6m parallel parking space). Compare this to the total length of our road network.

The Maltese Road Network

The Maltese road network consists of the following categories:

  1. Arterial roads (4%)
  2. Distributor roads (4%)
  3. Rural and Urban Roads with Linking function (92%)

The table below is extracted from NSO publication of 2001 and indicates the length in km of each road category divided between Malta and Gozo.

Cold joints in asphalt pavements FAQ

Cold joints are a necessary evil in road construction. They cannot be avoided but they can be planned. Following the correct procedures to work next to them will ensure that the risk of failure of the cold joint is decreased.

Cold joints in asphalt works cannot be eliminated. However, through proper planning and construction of joints the risk of failure at the joints can be reduced. This will ensure that the roads perform satisfactorily through their design life.

7 Asphalt Compaction Tips for Better Road Surfaces

Steel Drum Compactor

Switch OFF vibration in good time before reversing.

Pre-roll without vibration if there is a low pre-compaction by the paver.

Select vibrator frequency on asphalt mix type and laying thickness in line with recommendations from the roller manufacturer. Compact surface layers with high frequency rates. Thick layers from 8cm onwards shall be vibrated with low frequency rates.

DO NOT use excessive speed as you might create the washboarding effect.

Use static compaction when moving downhill. Use vibration only when moving uphill.

When the asphalt temperatures reach 100 degrees celsius switch off vibration to avoid the risk of crushing the aggregates, and will eventually lead to cracks. For the same reason, compact thin asphalt layers only with low vibration effects and few passes or better still entirely without vibration.

With dense mixtures, too much compaction at high temperatures may lead to bitumen being pushed to the surface layer. Consequently, the skid resistance of the road surface will be lowered.

10 Basic Rules for Better Asphalt Compaction

Asphalt Compaction

1. Start compaction as early as possible.

2. Drive with the driven drum towards the paver to avoid the formation of ripples and cracks. Combination rollers should be used with the rubber tyres towards the paver.

3. To avoid mix material sticking, drums and tyres must be lightly sprayed with water. They should be moist but not wet.

4. DO NOT use vibration when the machine is at a standstill. This will avoid the formation of waves.

5. Drive smoothly and do not change direction in jerky movements. The use of an automatic speed control system can improve the rolling quality.

6. Switch the vibration on only when the machine is moving. Switch the vibration off in good time before reversing.

7. If the road is cambered start compaction from the lower edge and overlap each pass towards the higher edge.

8. Steer and offset the machine only on compacted material to avoid shoving of asphalt.

9. Never stop the roller on hot mix material since the machine will probably cause deformation of the layer.

10. ALWAYS park the machine at an oblique angle to the direction of the work so that any marks can be smoothed out later.
