Editor's Notes
Longitudinal and transversal cracks were frequently observed. Alligator cracks in the wheel paths were also observed . During 1999 the road was rehabilitated by milling away the two upper layers of the existing structure that consisting of porous asphalt and dense asphalt concrete. After the milling operation levelling layers were placed and two new layers, a binder course and a porous asphalt as a wearing course.
Three sections each comprising of a length of 100-meter was chosen as test sections. One test section was reinforced with steel fabrics in both lanes, one test section was reinforced only in the slow traffic lane and one section was constructed without reinforcement as a reference road section.
The asphalt strain gauges used are of type H-shape and manufactured by Dynatest with three gauges per test section.

The Reference section is with the fine solid lines. The one-lane reinforced section is with dotted lines The two-lane reinforced section is with thick solid lines.
