MAINTENANCE OF ROAD SURFACES

摘要

Improved process for surface treatment of roads by separately applying a liquid asphalt binder and an aggregate. The improvement consists in that the load distribution of the road is determined before the dosage of the binder and that the dosage of the binder is then effected in accordance with the results of said determination. Measurements for determination of the hardness, the temperature profile during a year and the roughness of the road surface are also carried out in order to more exactly determine the optimal amount of the binder. A device for the measurement of the transverse load distribution is also disclosed.
