Σύνοψη

The road user desires a road surface where he can drive safe and comfortable. This requires a pavement structure with enough stiffness, a fast run-off from the rainwater, an even road surface, a good reflection of (artificial) light at the road surface and a limited production of noise in the contact area between the vehicle tire and the road surface. These properties should preferably be present during a long period of time, e.g. during the life of the pavement structure, about 20 years.
Firstly, on the uniformly compacted road-base, hot prime coat is spread using a distributor truck. After 24 hours any excess is removed and the truck transport the hot bitumen for the first layer, base-coarse, at the place of placement at the correct temperatures. Base course consist of more porous materials than the wearing course, which means is cheaper. Using paver bitumen is placed and compacted with a roller and a pneumatic tire roller.
After 24 hours tack coat is spayed on the base course and now it is ready to follow the same procedure for the wearing course. Care must give to joints, because bituminous pavements deteriorate easily.
When compaction finishes core samples are taken of the pavement and sent to the laboratory for tests, so the pavements suitability certificates to print out.
