DRIVING COST AND COMFORT ON SURFACE TREATMENT

AJOKUSTANNUKSET JA AJOMUKAVUUS SIROTEPINTAUKSELLA

The surface treatment method (sip) was introduced in Finland in 1975 for reconstruction of road surfacings. The use is limited to the road district of Turku, mainly on low volume local roads but also on main and secondary roads with a volume of 2000-5000 vehicles a day. Construction cost with grading amounts to about 10 fim/sq M while a wearing course of asphalt concrete costs 15-20 fim/sq M depending on layer thickness. Driving properties on wet surfaces and light-reflecting properties are better than on asphalt concrete. The friction is also better although it is not significant under Finnish conditions. Increased wear of tyres and higher fuel consumption are the major detriments of the method. Windshields also are in danger as stone chips detach from new surfacings. The rolling resistance of the new surface treatment is 19% higher than that of asphalt concrete and fuel consumption increases by 6% and the wear of tyres by 69%. The benefit in manufacturing is lost in increased driving cost during the first two years of the surface treatment. (TRRL)
