ANTI-SKID TREATMENT USING SAND/ABSOL AND CHIPS

HALKBEKAEMPNING MED ABSOLBLANDAT SAND OCH FLIS. FOERSOEK I STOCKHOLM VINTERN 1987-88

From the environmental point of view, use of salt/sand mixture for winter road maintenance is to be avoided. Tests have been made using a) mixture of sand/ABSOL (limestone product), b) chippings. Results in relation to conventional salt/sand mixture have been: 1. From the traffic safety standpoint, sand and chippings mixed with ABSOL produce equivalent road surfaces. Friction is raised both during spreading and in long term. 2. Cost is increased by up to SEK 2700/km/year for only skid prevention. Highest increase is due to sand/ABSOL. If increased snow clearance due to absence of melting effect is added, additional cost is SEK 3500-6200/km/year. 3. No practical handling problems have been encountered. This winter has however been mild with little snow, and tests are therefore not decisive. 4. When sand/ABSOL is used, covered storage areas are required; this necessitates investment. 5. Interviews show that people prefer both test materials to salt/sand mixture. 6. Chippings appear most promising for further tests. 7. Both materials must be quickly removed in the spring. With sand/ABSOL the quantity of latter is the same as when only ABSOL is spread; there are problems due to its being carried into buildings.
