MEASUREMENT OF SKIDDING RESISTANCE ON EN 366 (KM 18,5 AND 21,0) 3RD REPORT

MEDICOES DE RESISTENCIA A DERRAPAGEM NA EN 366 (KM 18,5 E 21,0) 3RD RELATORIO

As part of the observations on en 366 road, four more series of tests were carried out in which kenematic friction coefficients (skid-resistance) and pavement evenness were determined. The longitudinal gradient of the road at test points was measured as well as the depth of the water film on the pavement. The longitudinal evenness of the pavement was measured by means of the "Wisconsin Road Meter", and the transverse evenness was measured by means of the "Transverse Profilograph"; traffic surveys and searches in the accident archives of Direccao Geral De Viacao were also carried out. The results obtained are presented and the observations carried out are interpreted and compared with those of previous test series. It was found that the pavement was still in good condition. /TRRL/
